The manager supervises the administrative affairs of the city and carries out the policies established by the City Council. As the Chief Administrative Officer, the City Manager is responsible for the organization of the administrative branch and has

414-552: A lynching of an African-American man took place. On May 27, 1889, in the early morning, a mob of white men stormed the county jail to capture 23-year-old Albert Martin. A mixed-race man, he was accused of attacking a woman. They hanged him from the 7th Street Bridge. A memorial was installed in 2018 at the site, recounting Martin's history. The city collaborated with the Equal Justice Initiative on this memorialization. On November 11, 2017, veterans from around

552-475: A 2013 underwater discovery along the ridge. On the eve of European contact, the extent of development among Eastern Woodlands Native American societies is indicated by the archaeological evidence of a town on or near Lake Huron that contained more than one hundred large structures housing a total population of between 4,000 and 6,000. The French, the first European visitors to the region, often referred to Lake Huron as La Mer Douce, "the fresh-water sea". In 1656,

The surface area of the five primary lakes combined is roughly equal to the size of the United Kingdom, while the surface area of the entire basin (the lakes and the land they drain) is about the size of the UK and France combined. Lake Michigan

1380-529: A map by French cartographer Nicolas Sanson refers to the lake by the name Karegnondi , a Wyandot word that has been translated variously, as "Freshwater Sea", "Lake of the Hurons", or simply "lake". Generally, the lake was labeled "Lac des Hurons" (Lake of the Huron) on most early European maps. By the 1860s, many European settlements on the shores of Lake Huron were becoming incorporated , including Sarnia,

The for-profit company purchased the former St. Joseph Mercy Port Huron hospital in September 2015 from Trinity Healthcare . Upon completion of

1794-456: A nuisance to industries by clogging pipes. The U.S. Fish and Wildlife Service estimated in 2007 that the economic impact of the zebra mussel could be about $ 5 billion over the next decade. The alewife first entered the system west of Lake Ontario via 19th-century canals. By the 1960s, the small silver fish had become a familiar nuisance to beach goers across Lakes Michigan, Huron, and Erie. Periodic mass die-offs result in vast numbers of

1932-681: A possible reason for a decrease in population of various whitefish , important because of their culinary desirability and, hence, economic consequence. Moreover, between 1879 and 1899, reported whitefish harvests declined from some 24.3 million pounds (11 million kg) to just over 9 million pounds (4 million kg). By 1900, commercial fishermen on Lake Michigan were hauling in an average of 41 million pounds of fish annually. By 1938, Wisconsin's commercial fishing operations were motorized and mechanized, generating jobs for more than 2,000 workers, and hauling 14 million pounds per year. The population of giant freshwater mussels

2070-435: A profound food web change that took place in 2003. Lake trout have also been stocked for decades in an attempt to rehabilitate the species and today are largely self sustaining, especially in the northern half of the lake. Lake Huron has suffered recently by the introduction of a variety of new invasive species, including zebra and quagga mussels , the spiny water flea , and round gobies . The demersal fish community of

2208-560: A relatively small area of southeast Lake Michigan where savanna or prairie occasionally intruded). Logging, urbanization, and agriculture uses have changed that relationship. In the early 21st century, Lake Superior's shores are 91% forested, Lake Huron 68%, Lake Ontario 49%, Lake Michigan 41%, and Lake Erie, where logging and urbanization has been most extensive, 21%. Some of these forests are second or third growth (i.e. they have been logged before, changing their composition). At least 13 wildlife species are documented as becoming extinct since

2346-504: A result of the almost complete disappearance of the invasive Alewife in the lake). These native species include Lake Trout and Walleye . The Walleye population in Saginaw Bay area of Lake Huron reached recovery targets in 2009. Michigan Ontario Great Lakes The Great Lakes ( French : Grands Lacs ), also called the Great Lakes of North America , are a series of large interconnected freshwater lakes spanning

By surface area, Lake Huron is the second-largest of the Great Lakes, with a surface area of 23,007 square miles (59,590 km)—of which 9,103 square miles (23,580 km) lies in Michigan and 13,904 square miles (36,010 km) lies in Ontario—making it the third-largest fresh water lake on Earth (or the fourth-largest lake, if the Caspian Sea is counted as

2622-548: A row in 2020. Historic low water Lake levels tend to be the lowest in winter. The normal low-water mark is 1.00 foot (30 cm) below datum ( 577.5 ft or 176.0 m ). In the winter of 1964, Lakes Michigan and Huron reached their lowest level at 1.38 feet (42 cm) below datum. As with the high-water records, monthly low-water records were set each month from February 1964 through January 1965. During this twelve-month period, water levels ranged from 1.38 to 0.71 feet (42–22 cm) below Chart Datum. The all-time low-water mark

2760-489: A season, and can survive poor water quality conditions. The influx of parasitic lamprey populations after the development of the Erie Canal and the much later Welland Canal led to the two federal governments of the United States and Canada working on joint proposals to control it. By the mid-1950s, the lake trout populations of Lakes Michigan and Huron were reduced, with the lamprey deemed largely to blame. This led to

2898-746: A second fault line, the Saint Lawrence rift , formed approximately 570 million years ago, the basis for Lakes Ontario and Erie was created, along with what would become the Saint Lawrence River. The Great Lakes are estimated to have been formed at the end of the Last Glacial Period (the Wisconsin glaciation ended 10,000 to 12,000 years ago), when the Laurentide Ice Sheet receded. The retreat of

3036-581: A small percid fish from Eurasia, became the most abundant fish species in Lake Superior's Saint Louis River within five years of its detection in 1986. Its range, which has expanded to Lake Huron, poses a significant threat to the lower lake fishery. Five years after first being observed in the St. Clair River, the round goby can now be found in all of the Great Lakes. The goby is considered undesirable for several reasons: it preys upon bottom-feeding fish, overruns optimal habitat, spawns multiple times

3174-470: A temporary trading post and fort at this site in the 17th century. In 1814, following the War of 1812 , the United States established Fort Gratiot at the base of Lake Huron.

Reports about this issue on the U.S. side highlight five large municipal systems (those of Detroit, Cleveland, Buffalo, Milwaukee and Gary ) as being the largest current periodic sources of untreated discharges into the Great Lakes. The fish of the Great Lakes have anti-depressant drugs meant for humans in their brains, which has caused concerns. The number of American adults who take anti-depressant drugs rose from 7.7% of all American adults in 1999–2002 to 12.7% in 2011–2014. As

3864-415: Is former city clerk Pauline Repp. The city levies an income tax of 1 percent on residents and 0.5 percent on nonresidents. Federally, Port Huron is part of Michigan's 9th Congressional District , represented by Republican Lisa McClain , elected in 2022. Some of Port Huron's earliest industries were related to the agriculture industry. A large grain elevator was located on the St. Clair River just north of

4002-557: Is heavy. Pleasure boats can enter or exit the Great Lakes by way of the Erie Canal and Hudson River in New York. The Erie Canal connects to the Great Lakes at the east end of Lake Erie (at Buffalo, New York ) and at the south side of Lake Ontario (at Oswego, New York ). The lakes were originally fed by both precipitation and meltwater from glaciers which are no longer present. In modern times, only about 1% of volume per year

4140-692: Is now Port Huron, in exchange for their cession of lands under treaty for European-American settlement. But in 1836, under Indian Removal , the US forced the Ojibwa to move west of the Mississippi River and resettle in what are now the states of Wisconsin and Minnesota. In 1857, Port Huron became incorporated. Its population grew rapidly after the 1850s due a high rate of immigration: workers leaving poverty, famine, and revolutions in Europe were attracted to

4278-401: Is the largest lake, by surface area, that is entirely within one country, the United States. The Great Lakes began to form at the end of the Last Glacial Period around 14,000 years ago, as retreating ice sheets exposed the basins they had carved into the land, which then filled with meltwater. The lakes have been a major source for transportation, migration, trade, and fishing, serving as

Some of these peninsulas even contain smaller peninsulas, such as the Bruce , Keweenaw , Leelanau , Niagara , and Thumb peninsulas. Population centers on the peninsulas include Grand Rapids , Flint , and Detroit in Michigan along with London , Hamilton , Brantford , and Toronto in Ontario. Although the Saint Lawrence Seaway and Great Lakes Waterway make

5382-529: The Environmental Protection Agency have shown that when the mercury comes in contact with many of the bacteria and compounds in the fresh water, it forms the compound methyl mercury , which has a much greater impact on human health than elemental mercury due to a higher propensity for absorption. This form of mercury is not detrimental to a majority of fish types, but is very detrimental to people and other wildlife animals who consume

5520-690: The Finger Lakes region of New York, as well as in Prince Edward County, Ontario , on Lake Ontario's northeast shore. The Great Lakes have been observed to help intensify storms, such as Hurricane Hazel in 1954, and the 2011 Goderich, Ontario tornado , which moved onshore as a tornadic waterspout . In 1996, a rare tropical or subtropical storm was observed forming in Lake Huron, dubbed the 1996 Lake Huron cyclone . Rather large severe thunderstorms covering wide areas are well known in

5796-521: The Niagara Escarpment precludes all natural navigation, the four upper lakes are commonly called the "upper great lakes". This designation is not universal. Those living on the shore of Lake Superior often refer to all the other lakes as "the lower lakes", because they are farther south. Sailors of bulk freighters transferring cargoes from Lake Superior and northern Lake Michigan and Lake Huron to ports on Lake Erie or Ontario commonly refer to

5934-545: The Port Huron Statement , a New Left manifesto, was adopted at a convention of the Students for a Democratic Society . The convention did not take place within the actual city limits of Port Huron, but instead was held at a United Auto Workers retreat north of the city (now part of Lakeport State Park ). A historical marker will be erected on the site in 2025. Port Huron is the only site in Michigan where

6072-510: The biosphere . Since the 19th century, an estimated 160 new species have found their way into the Great Lakes ecosystem; many have become invasive; the overseas ship ballast and ship hull parasitism are causing severe economic and ecological impacts. According to the Inland Seas Education Association, on average a new species enters the Great Lakes every eight months. Introductions into the Great Lakes include

6210-414: The zebra mussel , which was first discovered in 1988, and quagga mussel in 1989. Since 2000, the invasive quagga mussel has smothered the bottom of Lake Michigan almost from shore to shore, and their numbers are estimated at 900 trillion. The mollusks are efficient filter feeders, competing with native mussels and reducing available food and spawning grounds for fish. In addition, the mussels may be

6348-584: The " snowbelts " receive regular snow fall from this localized weather pattern, especially along the eastern shores of the lakes. Snowbelts are found in Wisconsin, Michigan, Ohio, Pennsylvania, New York, and Ontario. Related to the lake effect is the regular occurrence of fog, particularly along the shorelines of the lakes. This is most noticeable along Lake Superior's shores. The lakes tend to moderate seasonal temperatures to some degree but not with as large an influence as do large oceans; they absorb heat and cool

Since 2008, archaeologists have discovered at least 60 stone constructions along the submerged ridge that are thought to have been used as hunting blinds by Paleo-Indians . That a trade network brought obsidian from Oregon almost ten thousand years ago to be used for toolmaking was confirmed by

6762-536: The Black River near 12th Avenue. A second chicory plant operated at 3rd and Court Streets in Port Huron, which would later be purchased by McMorran's son. The roadside weed which grew in areas of the Thumb and Saginaw Valleys was brought to Port Huron for processing and then shipped worldwide. Chicory was commonly used as a coffee substitute especially in wartime. Wartime also brought another industry to Port Huron:

6900-554: The Black River. It was originally built in 1888 by the E. B. Eddy Company . The Domtar mill also specializes in specialty papers for the medical and food service industries. Adjacent to the Domtar Mill is the site of the former Acheson Colloids Company. Dr. Edward Acheson in 1908 founded the company, which made a variety of chemical and carbon-based products. The factory was purchased by Henkel and closed in 2010. However, Henkel continues to manufacture ink and carbon products under

Until 1970, mercury was not listed as a harmful chemical, according to the United States Federal Water Quality Administration. In the 21st century, mercury has become more apparent in water tests. Mercury compounds have been used in paper mills to prevent slime from forming during their production, and chemical companies have used mercury to separate chlorine from brine solutions. Studies conducted by

9798-437: The first European vessel to sail the Great Lakes, Le Griffon also became the first ship lost on the Great Lakes. It was built in 1679 on the eastern shore of Lake Erie near Buffalo , New York . Robert Cavalier, Sieur de la Salle navigated across Lake Erie, up the Detroit River , Lake St. Clair and the St. Clair River out into Lake Huron. Passing the Straits of Mackinac, La Salle made landfall on Washington Island , off

9936-461: The fish that were studied by researchers from the Rochman Lab. About 50 million pounds (23 kt) of fish is harvested each year from Great Lakes which has raised concerns on how this might affect human health. Microscopic pieces of plastic have also been found in drinking water coming from Great Lakes. It is estimated that nearly 40 million people in the region rely on drinking water from

10074-443: The fish washing up on shore; estimates by various governments have placed the percentage of Lake Michigan's biomass which was made up of alewives in the early 1960s as high as 90%. In the late 1960s, the various state and federal governments began stocking several species of salmonids, including the native lake trout as well as non-native chinook and coho salmon; by the 1980s, alewife populations had dropped drastically. The ruffe ,

10212-443: The fish. Mercury has been known for health related problems such as birth defects in humans and animals, and the near extinction of eagles in the Great Lakes region. The amount of raw sewage dumped into the waters was the primary focus of both the first Great Lakes Water Quality Agreement and federal laws passed in both countries during the 1970s. Implementation of secondary treatment of municipal sewage by major cities greatly reduced

10350-499: The five lakes lie in separate basins, they form a single, naturally interconnected body of fresh water, within the Great Lakes Basin . As a chain of lakes and rivers, they connect the east-central interior of North America to the Atlantic Ocean. From the interior to the outlet at the Saint Lawrence River, water flows from Superior to Huron and Michigan, southward to Erie, and finally northward to Lake Ontario. The lakes drain

10488-417: The glaciers "rebounded" as it was uncovered. Since the glaciers covered some areas longer than others, this glacial rebound occurred at different rates. The Great Lakes have a humid continental climate, Köppen climate classification Dfa (in southern areas) and Dfb (in northern parts) with varying influences from air masses from other regions including dry, cold Arctic systems, mild Pacific air masses from

10626-410: The historical average level. Although "true tides—changes in water level caused by the gravitational forces of the sun and moon—do occur in a semi-diurnal (twice daily) pattern", such changes are quite small and generally obscured by other forces. The lake levels are affected primarily by changes in regional meteorology and climatology. The outflows from Lakes Superior and Ontario are regulated, while

10764-516: The hull. To keep from being pushed aground, they kept their bow into the wind with the engines running half to full in turns, yet the ship still drifted 800 feet (240 m) before its movement was arrested. Waves breaking over the ship damaged several windows, and the crew reported seeing portions of the concrete break wall peeling off as the waves struck it. Meanwhile, fifty miles farther up the lake, Matoa and Captain Hugh McLeod had to ride out

10902-491: The ice sheet left behind a large amount of meltwater ( Lake Algonquin , Lake Chicago , Glacial Lake Iroquois , and Champlain Sea ) that filled up the basins that the glaciers had carved, thus creating the Great Lakes as they are today. Because of the uneven nature of glacier erosion , some higher hills became Great Lakes islands. The Niagara Escarpment follows the contour of the Great Lakes between New York and Wisconsin. Land below

11040-554: The key indicators even in the current era of sophisticated analyses and measuring instruments. According to the bi-national (U.S. and Canadian) resource book, The Great Lakes: An Environmental Atlas and Resource Book : "The largest Great Lakes fish harvests were recorded in 1889 and 1899 at some 67,000 tonnes (66,000 long tons; 74,000 short tons) [147 million pounds]." By 1801, the New York Legislature found it necessary to pass regulations curtailing obstructions to

11178-612: The lake and causing blooms," said Michael McKay, executive director of the Great Lakes Institute for Environmental Research (GLIER) at the University of Windsor . The largest Lake Erie bloom to date occurred in 2015, exceeding the severity index at 10.5 and in 2011 at a 10. In early August 2019, satellite images depicted a bloom stretching up to 1,300 square kilometres on Lake Erie, with the heaviest concentration near Toledo, Ohio . A large bloom does not necessarily mean

11316-433: The lake bed was criss-crossed by a large network of tributaries to these ancient waterways, with many of the old channels still evident on bathymetric maps. The Alpena-Amberley Ridge is an ancient ridge beneath the surface of Lake Huron, running from Alpena, Michigan , southwest to Point Clark , Ontario. About 9,000 years ago, when water levels in Lake Huron were approximately 100 m (330 ft) below today's levels,

11454-437: The lake by the 1930s. The major native top predator, lake trout, was virtually extirpated from the lake by 1950 through a combination of overfishing and the effects of sea lamprey. Several species of ciscos were also extirpated from the lake by the 1960s; the only remaining native ciscoes are bloater and Cisco (lake herring). Non-native Pacific salmon have been stocked in the lake since the 1960s, but are less abundant since

11592-470: The lake include the North Channel and Georgian Bay . Saginaw Bay is located in the southwest corner of the lake. The main inlet is the St. Marys River from Lake Superior , and the main outlet is through the St. Clair River toward Lake Erie . Lake Huron has a fairly large drainage basin covering parts of Michigan and Ontario. Water flows through Lake Huron faster than the other Great Lakes with

11730-485: The lake is Manitoulin Island , which separates the North Channel and Georgian Bay from Lake Huron's main body of water. It is the world's largest lake island . A smaller bay that protrudes southwest from Lake Huron into Michigan is called Saginaw Bay . Cities with over 10,000 people on Lake Huron include Sarnia , the largest city on Lake Huron, and Saugeen Shores in Canada and Bay City , Port Huron , and Alpena in

11868-650: The lake shore as far north as the Grand Traverse Bay . Near Collingwood, Ontario , commercial fruit orchards, including a few wineries, exist near the shoreline of southern Nottawasaga Bay . The eastern shore of Lake Michigan and the southern shore of Lake Erie have many successful wineries because of the lakes' moderating effects, as do the large commercial fruit and wine growing areas of the Niagara Peninsula located between Lake Erie and Lake Ontario. A similar phenomenon allows wineries to flourish in

12006-430: The lake was in a state of collapse by 2006, and a number of drastic changes have been observed in the zooplankton community of the lake. Chinook salmon catches have also been greatly reduced in recent years, and lake whitefish have become less abundant and are in poor condition. These recent changes may be attributable to the new exotic species. Some native species, however were beneficiaries of these chances (principally

12144-538: The lakes has been observed since records began in 1918. The water level of Lake Michigan–Huron had remained fairly constant over the 20th century. Recent lake levels include record low levels in 2013 in Lakes Superior, Erie, and Michigan-Huron, followed by record high levels in 2020 in the same lakes. The water level in Lake Ontario has remained relatively constant in the same time period, hovering around

12282-470: The lakes' levels: diversion (the transfer of water to other watersheds) and consumption (substantially done today by the use of lake water to power and cool electric generation plants, resulting in evaporation). Outflows through the Chicago Sanitary and Ship Canal is more than balanced by artificial inflows via the Ogoki River and Long Lake/ Kenogami River diversions. Fluctuation of the water levels in

12420-458: The lakes. Only barges can access the Illinois Waterway system providing access to the Gulf of Mexico via the Mississippi River. Despite their vast size, large sections of the Great Lakes freeze over in winter, interrupting most shipping from January to March. Some icebreakers ply the lakes, keeping the shipping lanes open through other periods of ice on the lakes. The Great Lakes are connected by

12558-415: The lakes. The province of Ontario does not border Lake Michigan, and the state of Michigan does not border Lake Ontario. New York and Wisconsin's jurisdictions extend into two lakes, and each of the remaining states into one of the lakes. As the surfaces of Lakes Superior, Huron, Michigan, and Erie are all approximately the same elevation above sea level, while Lake Ontario is significantly lower, and because

12696-617: The largest city on Lake Huron. On October 26, 2010, the Karegnondi Water Authority was formed to build and manage a pipeline from the lake to Flint, Michigan . More than a thousand wrecks have been recorded in Lake Huron. Of these, 185 are located in Saginaw Bay, and 116 are found in the 448-square-mile (1,160 km) Thunder Bay National Marine Sanctuary and Underwater Preserve , which was established in 2000. Georgian Bay contains 212 sunken vessels. Purportedly

12834-401: The largest municipal marina system in the state and has five separate locations for boat mooring. The city has 14 public parks, 4 smaller-sized “tot” parks, 19 playgrounds (City owned), 9 playgrounds (School owned), 33 tennis courts, including 16 at schools and 6 indoors, 3 public beaches, 4 public swimming pools, 1 community center, and 1 public parkway. The city government is organized under

12972-468: The latter as the lower lakes and Lakes Michigan, Huron, and Superior as the upper lakes. This corresponds to thinking of lakes Erie and Ontario as "down south" and the others as "up north". Vessels sailing north on Lake Michigan are considered "upbound" even though they are sailing toward its effluent current. Lakes Huron and Michigan are sometimes considered a single lake, called Lake Michigan–Huron, because they are one hydrological body of water connected by

13110-494: The launch of the bi-national Great Lakes Fishery Commission . Several species of exotic water fleas have accidentally been introduced into the Great Lakes, such as the spiny waterflea, Bythotrephes longimanus , and the fishhook waterflea, Cercopagis pengoi , potentially having an effect on the zooplankton population. Several species of crayfish have also been introduced that may contend with native crayfish populations. More recently an electric fence has been set up across

13248-477: The mid 1970s. Emrick would go on to broadcast Olympic hockey games and Stanley Cup playoffs for NBC Sports , and is a frequent guest contributor to sister station WPHM . Port Huron was also represented in the Colonial Hockey League (also operating under the names United Hockey League and International Hockey League), with franchises from 1996 until the league folded in 2010. Originally called

13386-534: The morning, Senator pushed upstream. Less than an hour later, Manola —a propeller freighter of 2,325 gross register tons also built in Cleveland in 1890—passed through. Captain Frederick W. Light of Manola reported that both the Canadian and the American weather stations had storm flag signals flying from their weather towers. Following behind at 7:00 a.m. that Sunday, Regina steamed out of Sarnia into

13524-476: The natural migrations of Atlantic salmon from Lake Erie into their spawning channels. In the early 19th century, the government of Upper Canada found it necessary to introduce similar legislation prohibiting the use of weirs and nets at the mouths of Lake Ontario's tributaries. Other protective legislation was passed, but enforcement remained difficult. On both sides of the Canada–United States border,

13662-472: The northwest gale. The warnings had been up for four hours. Manola passed Regina off Port Sanilac, 22 statute miles (19 nmi; 35 km) up the lake. Captain Light determined that if it continued to deteriorate, he would seek shelter at Harbor Beach , Michigan, another 30 statute miles (26 nmi; 48 km) up the lake. There, he could seek shelter behind the breakwater. Before he reached Harbor Beach,

13800-467: The order amphipoda ), two types of copepods , and the deepwater sculpin (a spiny, large-headed fish). The Great Lakes are an important source of fishing . Early European settlers were astounded by both the variety and quantity of fish; there were 150 different species in the Great Lakes. Throughout history, fish populations were the early indicator of the condition of the Lakes and have remained one of

13938-516: The outflows of Michigan-Huron and Erie are not regulated at all. Ontario is the most tightly regulated, with its outflow controlled by the Moses-Saunders Power Dam , which explains its consistent historical levels. The Great Lakes contain 21% of the world's surface fresh water: 5,472 cubic miles (22,810 km ), or 6.0×10 U.S. gallons, that is 6 quadrillion U.S. gallons, (2.3×10 liters). The lakes contain about 84% of

14076-443: The population. There were 12,177 households, of which 32.5% had children under the age of 18 living with them, 34.5% were married couples living together, 19.9% had a female householder with no husband present, 5.6% had a male householder with no wife present, and 40.0% were non-families. 33.0% of all households were made up of individuals, and 11.8% had someone living alone who was 65 years of age or older. The average household size

14214-426: The power to appoint and remove administrative officers who are responsible for the operation of departments which carry out specific functions. The City Council consists of seven elected officials—a mayor and six council members. Beginning with the 2011 election, citizens voted separately for Mayor and Council. Council members will serve staggered four-year terms and the mayor will serve a two-year term. The current mayor

14352-516: The proliferation of dams and impoundments have multiplied, necessitating more regulatory efforts. Concerns by the mid-19th century included obstructions in the rivers which prevented salmon and lake sturgeon from reaching their spawning grounds. The Wisconsin Fisheries Commission noted a reduction of roughly 25% in general fish harvests by 1875. The states have removed dams from rivers where necessary. Overfishing has been cited as

14490-463: The region. Hydrologically , Lake Huron comprises the eastern portion of Lake Michigan–Huron , having the same surface elevation as Lake Michigan , to which it is connected by the 5-mile-wide (8.0 km), 20-fathom-deep (120 ft; 37 m) Straits of Mackinac . Combined, Lake Michigan–Huron is the largest freshwater lake by area in the world. The Huronian glaciation was named from evidence collected from Lake Huron region. The northern parts of

14628-626: The river from Sarnia, Ontario . The two cities are connected by the Blue Water Bridge at the eastern terminus of Interstate 94 . Port Huron has the easternmost point of land in the state of Michigan and is also one of the northernmost areas included in the Detroit–Warren–Dearborn Metropolitan Statistical Area ( Metro Detroit ). This area was long occupied by the Ojibwa people. French colonists had

14766-428: The routine discharge of untreated sewage during the 1970s and 1980s. The International Joint Commission in 2009 summarized the change: "Since the early 1970s, the level of treatment to reduce pollution from waste water discharges to the Great Lakes has improved considerably. This is a result of significant expenditures to date on both infrastructure and technology, and robust regulatory systems that have proven to be, on

14904-713: The sale, the formerly non-profit Catholic institution converted to a for-profit entity. CF Bancorp, a bank holding company for Citizens Federal Bank, was based in Port Huron. It was closed by regulators in April 2010 after it suffered from bank failure in the aftermath of the 2007–2008 financial crisis . There are currently four banks with a total of seven branches in the city containing $ 563 million in deposits, which are, in order of local deposit market share : JPMorgan Chase (2 branches), Huntington Bancshares (3 branches), Eastern Michigan Bank (1 branch), and Northstar Bank (1 branch). The first station to sign on in Port Huron

15042-420: The same lake'). Aggregated, Lake Huron-Michigan, at 45,300 square miles (117,000 km), "is technically the world's largest freshwater lake". Lake Superior, at 21 feet higher elevation, drains into the St. Marys River which then flows into Lake Huron. The water then flows south to the St. Clair River, at Port Huron, Michigan and Sarnia, Ontario . The Great Lakes Waterway continues thence to Lake St. Clair ;

15180-436: The shoreline of all the lakes would cover a distance roughly equivalent to travelling half-way around the world at the equator. A notable modern phenomenon is the formation of ice volcanoes over the lakes during wintertime. Storm-generated waves carve the lakes' ice sheet and create conical mounds through the eruption of water and slush. The process is only well-documented in the Great Lakes, and has been credited with sparing

15318-495: The site of the Municipal Office Center and the wastewater treatment plant. The Black River divides the city in half, snaking through Port Huron and emptying into the St. Clair River near Downtown. Port Huron has a humid continental climate ( Köppen climate classification Dfa ) with hot summers, cold winters and rain or snow in all months of the year. Port Huron is the largest city in the Thumb area, and

15456-602: The southern shorelines from worse rocky erosion. It has been estimated that the foundational geology that created the conditions shaping the present day upper Great Lakes was laid from 1.1 to 1.2 billion years ago, when two previously fused tectonic plates split apart and created the Midcontinent Rift , which crossed the Great Lakes Tectonic Zone . A valley was formed providing a basin that eventually became modern day Lake Superior. When

15594-549: The storm without a safe harbor. Matoa was found stranded on the Port Austin reef when the winds subsided. It was noon on Monday before the winds let up and not until 11:00 p.m. that night before Captain Light determined it to be safe to continue his journey. Although Manola survived the storm, she was renamed Mapledawn in 1920, and on November 24, 1924, she became stranded on Christian Island in Georgian Bay. It

15732-794: The storm. The people of Manitoulin Island say that the wreck in Mississagi Strait at the western tip of the island is that of Le Griffon . Meanwhile, others near Tobermory , say that the wreck on Russell Island , 150 miles (240 km) farther east in Georgian Bay, is that of Le Griffon . On November 9, 1913, the Great Lakes Storm of 1913 in Lake Huron sank 10 ships, and more than 20 were driven ashore. The storm, which raged for 16 hours, killed 235 seamen. Matoa—a propeller freighter measuring 2,311 gross register tons —had passed between Port Huron, Michigan, and Sarnia, Ontario, just after midnight. On November 9, just after six in

15870-542: The successful shipbuilding and lumber industries in Michigan. These industries supported development around the Great Lakes and in the Midwest. In 1859 the city had a total of 4,031 residents; some 1,855, or 46%, were foreign-born or their children (first-generation Americans). By 1870, Port Huron's population exceeded that of surrounding villages. In 1871, the State Supreme Court designated Port Huron as

16008-414: The surface freshwater of North America; if the water were evenly distributed over the entire continent's land area, it would reach a depth of 5 feet (1.5 meters). This is enough water to cover the 48 contiguous U.S. states to a uniform depth of 9.5 feet (2.9 m). Although the lakes contain a large percentage of the world's fresh water, the Great Lakes supply only a small portion of U.S. drinking water on

16146-407: The tip of the Door Peninsula on the Wisconsin side of Lake Michigan. La Salle filled Le Griffon with pelts and in late November 1679 sent Le Griffon back to the site of modern-day Buffalo, never to be seen again. Two wrecks have been identified as Le Griffon , although neither has gained final verification as the actual wreck. Blown by a fierce storm after leaving, Le Griffon ran aground before

16284-401: The total photosynthesis. By taking CO 2 out of the water to photosynthesize, diatoms help to stabilize the pH of the water, as CO 2 would react with water to produce carbonic acid . Port Huron, Michigan Port Huron is located along the source of the St. Clair River at the southern end of Lake Huron . The city is along the Canada–United States border and directly across

16422-562: The treatment plant, are temporarily overwhelmed by heavy rainstorms. Local sewage treatment authorities then must release untreated effluent, a mix of rainwater and sewage, into local water bodies. While enormous public investments such as the Deep Tunnel projects in Chicago and Milwaukee have greatly reduced the frequency and volume of these events, they have not been eliminated. The number of such overflow events in Ontario, for example,

16560-532: The tributary rivers into the Great Lakes also dislocated sediments. In 1884, the New York Fish Commission determined that the dumping of sawmill waste (chips and sawdust) had impacted fish populations. The first U.S. Clean Water Act , passed by a Congressional override after being vetoed by U.S. President Richard Nixon in 1972, was a key piece of legislation, along with the bi-national Great Lakes Water Quality Agreement signed by Canada and

16698-551: The vicinity of the former Fort Gratiot, was annexed by the city of Port Huron. The following historic sites have been recognized by the State of Michigan through its historic marker program. The city was hit by a violent F4 tornado on May 21, 1953 , damaging or destroying over 400 structures, killing two, and injuring 68. The city received the All-America City Award in 1955 and 2005. In June 1962,

16836-416: The warmer and shallower portions of the system such as Lake Erie, Saginaw Bay , Green Bay , and the southernmost portion of Lake Michigan. By the mid-1980s, most jurisdictions bordering the Great Lakes had controlled phosphate detergents . Blue-green algae, or cyanobacteria blooms, have been problematic on Lake Erie since 2011. "Not enough is being done to stop fertilizer and phosphorus from getting into

16974-430: The west pick up the air and moisture from the lake surface, which is slightly warmer in relation to the cold surface winds above. As the slightly warmer, moist air passes over the colder land surface, the moisture often produces concentrated, heavy snowfall that sets up in bands or "streamers". This is similar to the effect of warmer air dropping snow as it passes over mountain ranges. During freezing weather with high winds,

17112-427: The west, and warm, wet tropical systems from the south and the Gulf of Mexico. The lakes have a moderating effect on the climate; they can also increase precipitation totals and produce lake effect snowfall . The Great Lakes can have an effect on regional weather called lake-effect snow , which is sometimes very localized. Even late in winter, the lakes often have no icepack in the middle. The prevailing winds from

17250-480: The whole, quite effective." The commission reported that all urban sewage treatment systems on the U.S. side of the lakes had implemented secondary treatment, as had all on the Canadian side except for five small systems. Though contrary to federal laws in both countries, those treatment system upgrades have not yet eliminated combined sewer overflow events. This describes when older sewerage systems, which combine storm water with sewage into single sewers heading to

17388-443: The winds turned to the northeast and the lake began to rise. It was noon when he reached Harbor Beach and ran for shelter. The waves were so violent that Manola touched bottom entering the harbor. With help from a tugboat , Manola tied up to the break wall with eight lines. It was about 3:00 p.m. when Manola was secured and the crew prepared to drop anchor. As they worked, the cables began to snap from wind pressure against

17526-413: The world's surface fresh water). Because of their sea-like characteristics, such as rolling waves, sustained winds, strong currents, great depths, and distant horizons, the five Great Lakes have long been called inland seas . Depending on how it is measured, by surface area, either Lake Superior or Lake Michigan–Huron is the second-largest lake in the world and the largest freshwater lake. Lake Michigan

17664-567: The world. The second-largest island is Isle Royale in Lake Superior. Both of these islands are large enough to contain multiple lakes themselves—for instance, Manitoulin Island's Lake Manitou is the world's largest lake on a freshwater island. Some of these lakes even have their own islands, like Treasure Island in Lake Mindemoya in Manitoulin Island. The Great Lakes also have several peninsulas between them, including

17802-523: The zooplankton community of the lake. Scientists understand that the micro-aquatic life of the lakes is abundant but know very little about some of the most plentiful microbes and their environmental effects in the Great Lakes. Although a drop of lake water may contain 1 million bacteria cells and 10 million viruses , only since 2012 has there been a long-term study of the lakes' micro-organisms. Between 2012 and 2019 more than 160 new species have been discovered. Native habitats and ecoregions in

17940-509: Was 2.42 and the average family size was 3.03. The median age in the city was 35.8 years. 25.6% of residents were under the age of 18; 9.9% were between the ages of 18 and 24; 26.3% were from 25 to 44; 25.2% were from 45 to 64; and 13.1% were 65 years of age or older. The gender makeup of the city was 47.8% male and 52.2% female. A reference to the Port Huron Statement was made in the Coen Brothers film The Big Lebowski . In 2009,

18078-558: Was Ontario's Collingwood Harbour in 1994; Ontario's Severn Sound followed in 2003. Presque Isle Bay in Pennsylvania is formally listed as in recovery, as is Ontario's Spanish Harbour. Dozens of other Areas of Concern have received partial cleanups such as the Rouge River (Michigan) and Waukegan Harbor (Illinois). Phosphate detergents were historically a major source of nutrient to the Great Lakes algae blooms in particular in

18216-462: Was WAFD, which stood for We Are Ford Dealers . The station was owned by the Albert B. Parfet Company, a local Ford car dealership. WAFD signed on March 4, 1925 and signed off in 1926, with plans to relocate the station to Detroit. WHLS , coinciding with the opening of the Blue Water Bridge, signed on in 1938. It was founded by Harold Leroy Stevens and Fred Knorr . John Wismer became part owner of

18354-924: Was changed to the Keystone Ice Miners . Port Huron is also home to the Port Huron Prowlers of the Federal Prospects Hockey League . The Port Huron Pirates indoor football team dominated the Great Lakes Indoor Football League up until their departure to Flint, MI . McMorran Arena once again hosted indoor football with the Port Huron Predators of the Continental Indoor Football League in 2011. The Predators failed to finish

18492-539: Was declared a total loss. Salvagers were able to recover approximately 75,000 bushels of barley. Lake Huron has a lake retention time of 22 years. Like all of the Great Lakes, the ecology of Lake Huron has undergone drastic changes in the last century. The lake originally supported a native deepwater fish community dominated by lake trout , which fed on several species of ciscos as well as sculpins and other native fishes. Several invasive species , including sea lamprey , alewife and rainbow smelt , became abundant in

18630-477: Was eclipsed in January 2013. Lake Huron has the largest shore line length of any of the Great Lakes, counting its 30,000 islands. It is separated from Lake Michigan, which lies at the same level, by the 5-mile-wide (8.0 km), 20-fathom-deep (120 ft; 37 m) Straits of Mackinac, making them hydrologically the same body of water (sometimes called Lake Michigan-Huron and sometimes described as two 'lobes of

18768-517: Was eliminated as the mussels were harvested for use as buttons by early Great Lakes entrepreneurs. The Great Lakes: An Environmental Atlas and Resource Book (1972) notes: "Only pockets remain of the once large commercial fishery." Water quality improvements realized during the 1970s and 1980s, combined with successful salmonid stocking programs, have enabled the growth of a large recreational fishery. The last commercial fisherman left Milwaukee in 2011 because of overfishing and anthropogenic changes to

18906-429: Was found on the north bank of the Black River between Erie Street and Quay Street which is now a parking area for Bowl O Drome and Port Huron Kayak Launch. Ships built by Jenks includes: Port Huron is served by two acute care facilities, McLaren Port Huron (formerly known as Port Huron Hospital), and Lake Huron Medical Center (formerly known as St. Joseph Mercy Hospital Port Huron). McLaren Health Care Corporation ,

19044-617: Was one of only six similar bridges remaining in the US. According to the United States Census Bureau , the city has a total area of 12.26 square miles (31.75 km ), of which 8.08 square miles (20.93 km ) is land and 4.18 square miles (10.83 km ) is water. The city is considered to be part of the Thumb area of East-Central Michigan , also called the Blue Water Area . The easternmost point (on land) of Michigan can be found in Port Huron, near
