The Chesapeake Bay ( / ˈ tʃ ɛ s ə p iː k / CHESS -ə-peek ) is the largest estuary in the United States. The bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula , including parts of the Eastern Shore of Maryland , the Eastern Shore of Virginia , and the state of Delaware . The mouth of the bay at its southern point is located between Cape Henry and Cape Charles . With its northern portion in Maryland and the southern part in Virginia , the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the bay's 64,299-square-mile (166,534 km ) drainage basin , which covers parts of six states ( New York , Pennsylvania , Delaware , Maryland, Virginia, and West Virginia ) and all of Washington, D.C.

3813-438: The CBBT site) this can be seen as a lowest intertidal range. Two interesting points that arise from comparing these two sites at opposite ends of the bay are their tidal characteristics - semi-diurnal tide for CBBT and mixed tide for Baltimore (due to resonance in the bay) - and the differences in amplitude (due to dissipation in the bay). The bay is well-known for its seafood, especially blue crabs , clams , and oysters . In

At the point where the Susquehanna River flows into the bay, the average depth is 30 feet (9 m), although this soon diminishes to an average of 10 feet (3 m) southeast of the city of Havre de Grace, Maryland , to about 35 feet (11 m) just north of Annapolis. On average,

8610-437: The development of the skipjack (such as the Helen Virginia ), the state boat of Maryland, which is the only remaining working boat type in the United States still under sail power. Other characteristic bay-area workboats include sail-powered boats such as the log canoe , the pungy , the bugeye , and the motorized Chesapeake Bay deadrise , the state boat of Virginia. In addition to harvesting wild oysters, oyster farming

8733-770: The ecosystem. The nature-based recreation of wildlife, boating, and ecotourism are dependent on enforcement of the Clean Water Act (CWA), which regulates pollutant discharges and supports related pollution control programs. In 2006, "roughly eight million wildlife watchers spent $ 636 million, $ 960 million, and $ 1.4 billion in Maryland, Virginia, and Pennsylvania" according to the Chesapeake Bay Foundation . In colonial times, simple cooking techniques were used to create one pot meals like ham and potato casserole , clam chowder, or stews with common ingredients like oysters, chicken or venison. When John Smith landed in Chesapeake in 1608, he wrote: "The fish were so thick, we attempted to catch them with frying pans". Common regional ingredients in

8856-567: The entirety of the bay in about 3.3 days; by 1988 this time had increased to 325 days. The harvest's gross value decreased 88% from 1982 to 2007. One report suggested the bay had fewer oysters in 2008 than 25 years earlier. The primary problem is overharvesting . Lax government regulations allow anyone with a license to remove oysters from state-owned beds, and although limits are set, they are not strongly enforced. The overharvesting of oysters has made it difficult for them to reproduce, which requires close proximity to one another. A second cause for

8979-678: The first rivet into the keel of the SS ; Gunston Hall . In 1930, Alexandria annexed the town adjacent to Potomac Yard incorporated in 1908 named Potomac . In 1938 the Mt. Vernon Drive-In cinema opened. In 1939, the segregated public library experienced a sit-in organized by Samuel Wilbert Tucker . In 1940, both the Robert Robinson Library, which is now the Alexandria Black History Museum , and

9102-590: The first woman to be elected mayor. Until 2014, local legislation mandated that all new north–south streets in the city be named for Confederate military leaders . Efforts have increased in recent years to expedite the renaming of these streets with Mayor Justin Wilson and the City Council setting a goal of renaming three of these streets annually. In 2019, the name of U.S. 1 was changed from Jefferson Davis Highway to Richmond Highway. In November 2020,

9225-553: The geometry of the bay permits for a resonant period of 1.46 days. A good example of how the different Chesapeake Bay sites experience different tides can be seen in the tidal predictions published by the National Oceanographic and Atmospheric Administration (NOAA) (see figure at right). At the Chesapeake Bay Bridge–Tunnel (CBBT) site, which lies at the southernmost point of the bay where it meets

9348-446: The habitat for much of the bay's animal life. Beds of eelgrass , the dominant variety in the southern Chesapeake Bay, have shrunk by more than half there since the early 1970s. Overharvesting, pollution, sedimentation and disease have turned much of the bay's bottom into a muddy wasteland. The principal sources of nutrient pollution in the bay are surface runoff from farms, as well as runoff from urban and suburban areas. About half of

9471-458: The help of aquarium owners, who often dump the contents of their aquariums into nearby lakes and streams. It is highly invasive and has the potential to flourish in the low-salinity tidal waters of the Chesapeake Bay. Dense stands of Brazilian waterweed can restrict water movement, trap sediment and affect water quality. Various local K-12 schools in the Maryland and Virginia region often have programs that cultivate native bay grasses and plant them in

9594-569: The history of military psychology". William J. Strickland, HumRRO's President from 2008 to 2018, has also worked with the APA Division of Military Psychology and was recently elected to the fellow status of APA's Division 14: Society for Industrial and Organizational Psychology (SIOP). Alexandria, Virginia Alexandria is an independent city in the northern region of the Commonwealth of Virginia , United States. It lies on

9717-564: The hotel's proprietor. One of Ellsworth's soldiers immediately killed Jackson. Ellsworth was publicized as a Union martyr, and the incident generated great excitement in the North, with many children being named for him. Jackson's death defending his home caused a similar sensation in the South. Alexandria remained under military occupation until the end of the Civil War. Fort Ward , one of

9840-489: The idea and strongly favored a site at the head of Hunting Creek (also known as Great Hunting Creek). It has been said that in order to avoid a predicament the petitioners offered to name the new town Alexandria , in honor of Philip's family. As a result, Philip and his cousin Captain John Alexander (1711–1763) gave land to assist in the development of Alexandria and are thus listed as the founders. This John

9963-690: The lands in the Potomac River drainage area since at least the early 14th century . In the summer of 1608, English settler John Smith explored the Potomac River and came into contact with the Patawomeck (loosely affiliated with the Powhatan ) and Doeg tribes who lived on the Virginia side, as well as on Theodore Roosevelt Island , and the Piscataway (also known as the Conoy), who resided on

10086-477: The largest slave trading companies in the country. By the 1830s, they were sending more than 1,000 slaves annually from Alexandria to their Natchez, Mississippi , New Orleans , and later Texas markets to help meet the demand for slaves in Mississippi and nearby states. Later owned by Price, Birch & Co., the slave pen became a jail under Union occupation. A portion of the City of Alexandria—most of

10209-583: The late 16th century to found a colony, later settled at Roanoke Island (off the present-day coast of North Carolina ) for the Virginia Company , marked the first time that the English approached the gates to the Chesapeake Bay between the capes of Cape Charles and Cape Henry . Three decades later, in 1607, Europeans again entered the bay. Captain John Smith of England explored and mapped

10332-587: The late 19th and early 20th centuries. Until the mid-20th century, oyster harvesting rivaled the crab industry among Chesapeake watermen, a dwindling breed whose skipjacks and other workboats were supplanted by recreational craft in the latter part of the century. In the 1960s, the Calvert Cliffs Nuclear Power Plant on the historic Calvert Cliffs in Calvert County on the Western Shore of Maryland began using water from

10455-488: The leadership of a central chief. In 1524, Italian explorer Giovanni da Verrazzano , (1485–1528), in service of the French crown , (famous for sailing through and thereafter naming the entrance to New York Bay as the " Verrazzano Narrows ", including now in the 20th century, a suspension bridge also named for him ) sailed past the Chesapeake, but did not enter the bay. Spanish explorer Lucas Vásquez de Ayllón sent an expedition out from Hispaniola in 1525 that reached

10578-415: The legislature and fell out of favor in the mid-1750s. The town of Alexandria did not become incorporated until 1779. In 1755, General Edward Braddock organized his fatal expedition against Fort Duquesne at Carlyle House in Alexandria. In April 1755, the governors of Virginia, and the provinces of Maryland , Pennsylvania , Massachusetts , and New York met to determine upon concerted action against

10701-450: The local cuisine of Chesapeake included terrapins , smoked hams, blue crab, shellfish, local fish, game meats and various species of waterfowl. Blue crab continues to be an especially popular regional specialty. In the 1970s, the Chesapeake Bay was found to contain one of the planet's first identified marine dead zones , where waters were so depleted of oxygen that they were unable to support life, resulting in massive fish kills . In 2010

10824-544: The marine ecosystem. The word Chesepiooc is an Algonquian word referring to a village 'at a big river'. It is the seventh-oldest surviving English placename in the United States, first applied as Chesepiook by explorers heading north from the Roanoke Colony into a Chesapeake tributary in 1585 or 1586. The name may also refer to the Chesapeake people or the Chesepian, a Native American tribe who inhabited

10947-472: The middle of the 20th century, the bay supported 9,000 full-time watermen, according to one account. Today, the body of water is less productive than it used to be because of runoff from urban areas (mostly on the Western Shore) and farms (especially on the Eastern Shore and in the Susquehanna River watershed), over-harvesting, and invasion of foreign species . The plentiful oyster harvests led to

11070-522: The mouths of the Chesapeake and Delaware Bays . It may have been the first European expedition to explore parts of the Chesapeake Bay, which the Spaniards called "Bahía de Santa María" ("Bay of St. Mary") or "Bahía de Madre de Dios."("Bay of the Mother of God") De Ayllón established a short-lived Spanish mission settlement, San Miguel de Gualdape , in 1526 along the Atlantic coast . Many scholars doubt

11193-411: The nation . Like the rest of Northern Virginia and Central Maryland , present-day Alexandria has been influenced by its proximity to the U.S. capital. It is largely populated by professionals working in the federal civil service , in the U.S. military , or for one of the many private companies which contract to provide services to the U.S. federal government . The city's largest employers include

11316-414: The native oyster population. The health of the Chesapeake Bay improved in 2015, marking three years of gains over a four-year period. Slight improvements in water quality were observed in 2021, compared to indicators measured in 2020. The bay is experiencing other environmental concerns, including climate change which is causing sea level rise that erodes coastal areas and infrastructure and changes to

11439-591: The nature of the topography (both horizontal and vertical shape), wind-driven circulation, and how the bay interacts with oceanic tides. Research into the peculiar behavior of tides both at the northern and southern extents of the bay began in the late 1970s. One study noted sea level fluctuations at periods of 5 days, driven by sea level changes at the bay's mouth on the Atlantic coast and local lateral winds, and 2.5 days, caused by resonant oscillations driven by local longitudinal winds, while another study later found that

11562-407: The northern portion of the bay, experiences a noticeable modulation to form its mixed tidal nature during spring vs. neap tides. Spring tides, when the sun-earth-moon system forms a line, cause the largest tidal amplitudes during lunar monthly tidal variations. In contrast, neap tides, when the sun-earth-moon system forms a right angle, are muted, and in a semi-diurnal tidal system (such as that seen at

11685-409: The northernmost point on the bay. North of Baltimore , the western shore borders the hilly Piedmont region of Maryland; south of the city the bay lies within the state's low-lying coastal plain , with sedimentary cliffs to the west, and flat islands, winding creeks and marshes to the east. The large rivers entering the bay from the west have broad mouths and are extensions of the main ria for miles up

11808-536: The nutrient pollutant loads in the bay are generated by manure and poultry litter. Extensive use of lawn fertilizers and air pollution from motor vehicles and power plants are also significant nutrient sources. One particularly harmful source of toxicity is Pfiesteria piscicida , which can affect both fish and humans. Pfiesteria caused a small regional panic in the late 1990s when a series of large blooms started killing large numbers of fish while giving swimmers mysterious rashes; nutrient runoff from chicken farms

11931-411: The nutrients phosphorus and nitrogen . The algae prevents sunlight from reaching the bottom of the bay while alive and deoxygenates the bay's water when it dies and rots. Soil erosion and runoff of sediment into the bay, exacerbated by devegetation, construction and the prevalence of pavement in urban and suburban areas, also block vital sunlight. The resulting loss of aquatic vegetation has depleted

12054-676: The oligohaline zone is north Baltimore and the south end is the Chesapeake Bay Bridge. The mesohaline zone has a medium amount of salt and runs from the Bay Bridge to the mouth of the Rappahannock River . Salinity there ranges from 1.07% to 1.8%. The polyhaline zone is the saltiest zone, and some of the water can be as salty as sea water. It runs from the mouth of the Rappahannock River to the mouth of

12177-403: The oyster depletion is that the drastic increase in human population caused a sharp increase in pollution flowing into the bay. The bay's oyster industry has also suffered from two diseases: MSX and Dermo . The depletion of oysters has had a particularly harmful effect on the quality of the bay. Oysters serve as natural water filters, and their decline has further reduced the water quality of

12300-404: The population was: In 2000, there were 61,889 households, of which 18.6% had children under the age of 18 living with them, 32.2% were married couples living together, 9.2% had a female householder with no husband present, and 55.2% were non-families. 43.4% of all households were made up of individuals, and 6.8% had someone living alone who was 65 years of age or older. The average household size

12423-475: The port of Georgetown and the Chesapeake and Ohio Canal fostered development on the north side of the Potomac River, Alexandria's economy stagnated; at the same time, residents had lost any representation in Congress and the right to vote and were disappointed with the negligible economic benefit (on the Alexandria side) of being part of the national capital. Alexandria still had an important port and market in

12546-517: The ports of Wilmington and Philadelphia on the Delaware River . During the later half of the 19th century and the first half of the 20th century, the bay was plied by passenger steamships and packet boat lines connecting the various cities on it, notably the Baltimore Steam Packet Company ("Old Bay Line"). In the later 20th century, a series of road crossings were built. One, the Chesapeake Bay Bridge (also known as

12669-531: The route of Smith's historic 17th-century voyage. Because of economic hardships and civil strife in the "Mother Land", there was a mass migration of southern English Cavaliers and their servants to the Chesapeake Bay region between 1640 and 1675, to both of the new colonies of the Province of Virginia and the Province of Maryland . The Chesapeake Bay was the site of the Battle of the Chesapeake (also known as

12792-562: The runoff of residential, farm and industrial waste throughout the watershed. A 2010 report criticized Amish farmers in Pennsylvania for raising cows with inadequate controls on the manure that they generate. Farms in Lancaster County, Pennsylvania generate large quantities of manure that washes into tributaries of the bay. The pollution entering the bay has multiple components that contribute to algal blooms, principally

12915-408: The school board unanimously voted to rename T. C. Williams High School and Matthew Maury Elementary School. The high school was renamed Alexandria City High School and Maury Elementary was renamed Naomi L. Brooks Elementary School, effective July 1, 2021. In December 2023, Virginia Governor Glenn Youngkin and Monumental Sports & Entertainment founder Ted Leonsis announced plans to develop

13038-623: The siege of Battle of Yorktown in Yorktown, Virginia . Their marching route from Newport, Rhode Island through Connecticut, New York State, Pennsylvania, New Jersey and Delaware to the "Head of Elk" by the Susquehanna River along the shores and also partially sailing down the bay to Virginia . It is also the subject of a designated National Historic Trail as the Washington–Rochambeau Revolutionary Route . The bay would again see conflict during War of 1812 . During

13161-408: The south by Fairfax County . The western portions of the city were annexed from those two entities beginning in the 1930s. The addressing system in Alexandria is not uniform and reflects the consolidation of several originally separate communities into a single city. In Old Town Alexandria , building numbers are assigned north and south from King Street and west (only) from the Potomac River. In

13284-470: The surface of the bay to freeze in winter, something that happened most recently in the winter of 1976–77. The Chesapeake Bay is the end point of over 150 rivers and streams. The largest rivers flowing directly into the bay, in order of discharge, are: For more information on Chesapeake Bay rivers, see the List of Chesapeake Bay rivers . The Chesapeake Bay is home to numerous fauna that either migrate to

13407-540: The town's destruction, twenty-two merchant ships and large quantities of flour , tobacco , cotton , wine , and sugar were handed over by Alexandria's municipal authorities to the British. In 1823 William Holland Wilmer , Francis Scott Key , and others founded the Virginia Theological Seminary . From 1828 to 1836, Alexandria was home to the Franklin & Armfield Slave Market, one of

13530-616: The turn of the 20th century the most common production in the city was glass, fertilizer, beer, and leather. The glass often went into beer bottles. Much of the Virginia Glass Company effort went to supply the demands of the Robert Portner Brewing Company, until fire destroyed the St. Asaph Street plant on February 18, 1905. The Old Dominion Glass Company also had a glass works fall to fire, then built

13653-594: The vice president did not yet have an official residence . Following the resignation of Richard Nixon , Ford spent his first 10 days as President in the house before moving to the White House . In March 1959, Lieutenant Colonel William Henry Whalen , the "highest-ranking American ever recruited as a mole by the Russian Intelligence Service ", provided Colonel Sergei A. Edemski three classified Army manuals in exchange for $ 3,500 at

13776-468: The western bank of the Potomac River approximately 7 miles (11 km) south of downtown Washington, D.C. Alexandria is the third-largest principal city of the Washington metropolitan area , which is part of the larger Washington–Baltimore combined statistical area . As of 2022, the city's population of 159,467 made it the sixth-most populous city in Virginia and the 173rd-most populous city in

13899-785: The western boundary of the Northern Neck Proprietary , when the Privy Council in London found in favor of Lord Fairfax's expanded claim, some of the Fairfax County gentry formed the Ohio Company of Virginia. They intended to conduct trade into the interior of America, and they required a trading center near the head of navigation on the Potomac. The best location was Hunting Creek tobacco warehouse, since

14022-448: The year of 1813, from their base on Tangier Island , British naval forces under the command of Admiral George Cockburn raided several towns on the shores of the Chesapeake, treating the bay as if it were a "British Lake". The Chesapeake Bay Flotilla , a fleet of shallow-draft armed barges under the command of U.S. Navy Commodore Joshua Barney , was assembled to stall British shore raids and attacks. After months of harassment by Barney,

14145-516: Was $ 103,284 and median family income was $ 130,395. Additionally, 8.6% of the population of the population were below the poverty line. 14.2% of those under the age of 18 and 3.1% of those 65 and older were living below the poverty line. According to 2022 American Community Survey 1-Year Estimates, 69.9% of Alexandria residents aged 25 and older have attained a bachelor's degree or higher, compared with 42.2% statewide. Companies headquartered in Alexandria include Crooked Beat Records , Five Guys ,

14268-415: Was 2.04 and the average family size was 2.87. The age distribution was 16.8% under the age of 18, 9.2% from 18 to 24, 43.5% from 25 to 44, 21.5% from 45 to 64, and 9.0% who were 65 years of age or older. The median age was 34 years. For every 100 females, there were 93.5 males. For every 100 females aged 18 and over, there were 91.7 males. According to 2019 Census Bureau data, the median household income

14391-409: Was blamed for the growth. While the bay's salinity is ideal for oysters and the oyster fishery was at one time the bay's most commercially viable, the population has in the last fifty years been devastated. Maryland once had roughly 200,000 acres (810 km ) of oyster reefs. In 2008 there were about 36,000 acres (150 km ). It has been estimated that in pre-colonial times, oysters could filter

14514-470: Was conducted on July 13–14, 1749. Almost immediately upon establishment, the town founders called the new town "Belhaven", believed to be in honor of a Scottish patriot, John Hamilton, 2nd Lord Belhaven and Stenton , the Northern Neck tobacco trade being then dominated by Scots. The name Belhaven was used in official lotteries to raise money for a Church and Market House, but it was never approved by

14637-463: Was divided with men hunting while the women supervised the village's farming. All village members took part in the harvesting of fish and shellfish from the local bodies of water. As time went on, communities around the Chesapeake Bay formed confederations such as the Powhatan , the Piscataway , and the Nanticoke . Each of these confederations consisted of a collection of smaller tribes falling under

14760-492: Was introduced by Lawrence Washington , the representative for Fairfax County, the son-in-law of William Fairfax , and a founding member of the Ohio Company. To support the company's push for a town on the river, Lawrence's younger brother George Washington , an aspiring surveyor, made a sketch of the shoreline touting the advantages of the tobacco warehouse site. Since the river site was amidst his estate, Philip opposed

14883-470: Was re-chartered in 1852 and became independent of Alexandria County in 1870. The remaining portion of Alexandria County changed its name to Arlington County in 1920. The first fatalities of the North and South in the American Civil War occurred in Alexandria. Within a month of the Battle of Fort Sumter , the Civil War's first battle, Union Army troops occupied Alexandria, landing troops at

15006-551: Was terminated at the end of 1975. There are close historical connections between HumRRO and the American Psychological Association (APA). Meredith Crawford, the founder of HumRRO also served as the President of the APA's Division 19: Society for Military Psychology. Peter Ramsberger of the APA said that Crawford was "the founder and effective leader of one of the most important research organizations in

15129-681: Was the son of Robert Alexander II (1688–1735). On May 2, 1749, the House of Burgesses approved the river location and ordered "Mr. Washington do go up with a Message to the Council and acquaint them that this House have agreed to the Amendments titled An Act for erecting a Town at Hunting Creek Warehouse, in the County of Fairfax." A "Public Vendue" (auction) was advertised for July, and the county surveyor laid out street lanes and town lots. The auction
