The smoke floated out through a corresponding hole in center of the roof. Earth was also piled on the outside of the Hu for additional insulation. K’um was a partially subterranean dwelling where ceremonial practice and dances took place. These structures were more prominent in larger villages. The K’um also provided lodging for visitors. The floor of

380-556: A different variation of the Nisenan language , researchers have inconsistent linguistic data on the language. Early documentation about the social organization of the tribe failed to account for the female Nisenan perspective, their voices and inclusion. Researchers concluded that the Nisenan were a patriarchal society , that they adhered to a patrilocal residence system, and followed a system of patrilineal leader succession. Because of

456-419: A fire and collected. Shell beads were used as a display of wealth and a form of currency. The beads were not shaved down by the Nisenan but were imported from coastal communities. Once worn down the shell beads were punctured, so they could be strung on strings. This currency was not always used with outside tribes. The Valley Nisenan and Hill Nisenan frequently traded with each other. The Nisenan who lived in

532-524: A large dam on the American River by the late 19th century. During the 20th century, the American River was extensively developed for flood control, hydroelectricity production and irrigation. Folsom Dam is the primary flood-control facility for Sacramento. The numerous hydroelectric dams upstream on the Middle and South Forks are not constrained by flood control requirements; rather, the needs of electricity and water supply govern their operation. Folsom Dam

608-415: A mourning period of six months to three years; men were allowed to remarry sooner than the women. Many women most often opted to return to their own people than to remarry. Marriage to a husband's brother was also an option. Before any decisions to remarry, permission from deceased spouse's relatives was necessary as a form of respect. Funeral burning rituals are one of the most prominent death ceremonies in

684-610: A sharp curve northward to descend into Tahoe Valley. The South Fork has multi-use recreational areas, including the Rubicon Trail for motorized adventuring and whitewater rafting venues. The South Fork also features the historic town of Coloma , where the California Gold Rush began in 1848. Trout fishing and recreational gold panning are popular activities on the South Fork. The Silver Fork American River

760-626: A strain on resources and the environment. When a drought took place, crops failed and people died of starvation. The Nisenan population dropped precipitously from approximately 9,000 to 2,500 people by 1895. A fraction of the surviving Nisenan remained in the Sierra Nevada foothills and acquired low-wage jobs. Documented history about customs can be contradictory and not always reliable, as early anthropologists were often researching several regions at once, often well after disruptions and trauma to tribes had already occurred due to European contact. According to some sources, if twins were born, they and

The Sacramento County Regional Parks owns most of the land that is operated by the American River Parkway. This area serves the citizens of Sacramento and visitors from away with access to the river and parks, picnic areas, biking and jogging paths, trails for hiking, and habitat for fish and wildlife. Chinook Salmon are

1824-746: The ablative plural pronoun nisena·n ,. The Nisenan have been called the Southern Maidu and Valley Maidu. While the term Maidu is still used widely, Maidu is an over-simplification of a very complex division of smaller groups or bands of Native Americans. The Nisenan live in Northern California, between the Sacramento River to the west and the Sierra Mountains to the east. The southern reach went to about Cosumnes River but north of Elk Grove and

1900-546: The confluence with the Middle Fork American River at Auburn . Below the confluence, the North Fork continues several miles until reaching Folsom Lake. Both the North Fork and Middle Fork feature archaeological and historic sites of ancient Native American culture and 1850s Gold Rush habitation. The Middle Fork is 62 miles (100 km) long. It originates a mere 1.7-mile (2.7 km) from

1976-546: The American River include: Native plants include: Historically, the American River, like many other rivers in California, were modified by the dams of beavers, until European trappers removed many of the beavers from their native habitat for their fur. Since the California Gold Rush was centered in an area that included the American River basin, it was one of the earlier California rivers to be populated, beginning at Leidesdorff Ranch, owned by William Leidesdorff . Water

2052-580: The American River, near the present-day location of central Sacramento. In 1848, following the Mexican–American War , California was ceded to the United States in the Treaty of Guadalupe Hidalgo . Just weeks later, James W. Marshall , an employee of Sutter, discovered gold on the South Fork, starting the California Gold Rush . Although miners looking to extract gold worked all three forks of

2128-444: The American River, the South Fork held the richest deposits. As the easily accessible placer gold was played out, large companies used hydraulic mining to access gold buried deeper in the soil. This large and extensive mining practice washed away entire mountainsides and heavily polluted all the waterways, including the American River, creating an environmental disaster for inhabitants, fish, birds, and other flora and fauna. During

2204-543: The Cosumnes River and Yuba River, as well as in the Sacramento Valley between the American River and Feather River. There were as many as 13 specific Nisenan dialects. Eight are documented. They were previously documented as four dialects, classified as: The Spanish invaded and occupied Alta California in the late 18th century. Franciscan missions were built in California to settle the area, spread

2280-625: The Jones Fork Powerhouse. From Union Valley, water flows through the Union Valley Powerhouse to Junction Reservoir, then through Jaybird Powerhouse to Camino Reservoir, both on Silver Creek. The water then enters a penstock that feeds the Camino Powerhouse above Slab Creek Reservoir on the South Fork American River. From there, water is sent through a final tunnel to White Rock Powerhouse, located on

2356-533: The K’um was partially dug in below ground level. The door was oriented to the east. The K’um had two to four major posts depending on its size for support. An abundant source of food came from acorns . In the fall, villagers helped to forage for acorns. Long poles were used to acquire the acorns. Acorns were harvested in a granary. Acorns were then ground and made into mush, gruels, or cakes. Pine nuts, berries, and other sorts of vegetations were harvested as well. Tule root

Neighboring tribes included the Valley and North Sierra Miwok to the south, the Washoe to the east, the Konkow and Maidu to the north, and the Patwin to the west. The Nisenan were initially unaffected by European influence. In

2508-613: The Middle Fork has Class IV rapids, and the North Fork has Class IV spring run-off rapids. All three rivers also feature Class II sections. The areas with rapids still feature scenic views and wildlife, which is what makes it the most popular whitewater rafting location in California The California Office of Environmental Health Hazard Assessment has issued safe eating advice based on levels of mercury and polychlorinated biphenyl for fish caught from

2584-463: The Nisenan are a separate Tribe with their own Cultural lifeways, their own leaders and holy people, a distinct geographic territory and their own ancient and unique language." The Nisenan have been delineated by their geographical location, and so in many texts they are further subcategorized as the Valley Nisenan, Hill Nisenan, and Mountain Nisenan. Because of these geographical barriers,

2660-454: The Nisenan community. It included cremation of the body, and also of all of the deceased person's possessions. Cremation was the most feasible practice for tribes, primarily for those of a nomadic lifestyle, due to easier transportation and to limit grave robberies. The dead were reported to mingle in the surrounding space, before going to a land of the dead, an area that did not discriminate between good or bad. The deceased were thought to have

All three forks are known for their verdant canyons, forested ridges, massive rock formations, trails, back-country winter adventuring among snowy peaks, fishing and white water rafting . There are various fish species that live within the American River such as Chinook Salmon and Steelhead Trout. The American River headwaters lie along about 50 miles (80 km) along

2812-627: The Rancheria System in California. Although 27 out of 38 Rancherias as well as additional tribes have been restored throughout the past 25 years, the Nisenan were the first to be denied restoration of their Rancheria in 2015. This withheld them from federal health and housing services, education programs, and job assistance programs. Today, 87 percent of the tribe live along or below California's poverty line. Extremely high rates of under-education, under-employment, drug and alcohol addiction, domestic violence, suicide, and poor health persist within

2888-533: The Roman Catholic religion, extract resources from the land, and enslave indigenous people for their labor. The Nisenan people had less interaction with Spanish settlers from the coast compared to neighboring tribes. They were relatively undisturbed by Spanish missionaries and religious missions, though Spanish and Mexican troops occasionally set foot on Nisenan land to capture enslaved indigenous people who had fled (many of whom in one particular example were of

During this time, Alta California was part of New Spain ; however in 1822, Mexico gained its independence from Spain and took control of California. In the 1830s, fur trappers of the Hudson's Bay Company (HBC) visited the area to trap beaver and otter. During one of these expeditions, smallpox or malaria were accidentally introduced to

3268-492: The Truckee River. During most years, a significant snow-pack builds up in the Sierra Nevada which provides water during the hot, dry summers. In warmer winters much of the precipitation may fall as rain instead, causing flooding, but resulting in lower summer flows due to the lack of snow. Due to California's highly variable weather patterns, runoff volumes in the American River can rise and fall drastically from one year to

They believed there was a distinguishable boundary between the living and dead. The mention of a deceased person's name was greatly discouraged. The Nisenan language encompasses 13 dialects that are as extensive as the language itself. The language is spoken in the Sierra Nevada, between

3420-485: The city of Sacramento undertook a massive project to raise its streets and buildings as much as 9.5 feet (2.9 m). Many of original sidewalks and the first floors of buildings remain as subterranean spaces underneath today's streets. The lower American River has been one of seven California rivers to achieve the designation "Recreational River" under both the California Wild and Scenic Rivers Act (1972) and

3496-407: The community. The main goal of the Nisenan people is to restore their identity and re-establish representation of their tribe. Nisenan Heritage Day is held annually to showcase ceremonial dances and allow attendees insight as well as participation in traditional practices such as basket weaving. Additional efforts are put towards educating people on their language as they view it as their "connection to

3572-496: The couple themselves, but the parents chose the arrangements in older customs. Once both of their parents reached an agreement on the pairing, the couple was officially engaged. Shells and beads were gifted between the two families, and an event was arranged to celebrate their communion. Before the union was consummated, the couple was educated on their specific marital responsibilities. The man proved his ability to care for his wife by providing gifts to his in-laws. Couples moved from

The American River Conservancy protects the American River watershed to preserve the cultural and historic values of the river systems and the landscapes surround them. They are also invested in keeping the American River for recreational activities as well as its natural scenic views. The American River

3724-511: The early nineteenth century, their initial encounters with Spanish and U.S. expeditions were peaceful. In 1833, a severe malaria epidemic spread, which killed many of the Nisenan as well as other neighboring tribes. The 1849 Gold Rush attracted hundreds of thousands of Europeans to the area, resulting in appropriation of their lands, decimation of their resources, more disease, violence, and mass murder. The influx of numerous migrants resulted in overuse of land, competition for game and water, and

3800-538: The exception of Folsom Lake, Union Valley is the largest in the American River watershed, storing 277,000 acre-feet (0.342 km ) of water. The Upper American River Project produces 1.8 billion kilowatt hours in an average year, enough for about 20 percent of Sacramento's electricity needs. The SMUD plants are run on a peaking basis, although recreational boating and environmental flow requirements constrain their operation slightly. A number of run-of-the-river hydroelectric plants are located further downstream on

3876-432: The first power generation from UARP came online at Jaybird Powerhouse on May 1, 1961. Most of the project facilities were completed by 1967. The Loon Lake Powerhouse was completed in 1971, and Jones Fork Powerhouse was finished in 1985. Environmental impacts include the prevention of fish passage by the project's dams, which segment parts of the upper South Fork American River, the Rubicon River and their tributaries. Water

Fourteen environmental watershed groups are shown to be active in the Upper American River Watershed by the Adopt A Watershed Program of the U.S. EPA . The Upper American River Foundation is a prominent one. There are over 40 species of native and non-native fish in the American River, including: Wildlife in the American River basin includes: Invasive plants on

4104-628: The larger group of Native Americans known as the Maidu , though some dispute the accuracy of this relationship, including the Nisesan themselves. According to the Nisenan website, the United States' claim that they are Maidu is a misclassification and is inaccurate. As the Nisenan put it, "Like many other Tribes throughout the United States, the Nisenan have been misidentified and mislabeled. The Nisenan have been lumped together under inaccurate labels such as " Maidu ", "digger" and " southern Maidu ". However,

4180-525: The local Native peoples, who had no immunity to European diseases. Some accounts suggest as much as 70 percent of the indigenous population was wiped out. The surviving natives became hostile to exploitative European settlers and traders for quite some time, and prevented the HBC from establishing a permanent outpost here. In 1839, Swiss immigrant John Sutter established the New Helvetia settlement on

4256-604: The most biologically diverse habitats in North America. The North Fork features scenic multi-use trails along forested ridge-tops and riparian corridors. It flows freely as a designated National Wild and Scenic Rivers System river until reaching the North Fork Dam, which was built to contain mining debris. This dam creates the small Lake Clementine just north of the Foresthill Bridge and upstream of

4332-580: The mother were often killed. But Richard B. Johnson, current Tribal Chairman for the Nevada City Nisenan, said, "Our elders have said that twins were not killed, but were considered fortunate if both survived during infancy. Our tribe has ancestors who are twins." Due to a high frequency of stillborn births, the people did not make cradleboards until after the successful birth of a child. An expectant mother close to giving birth avoided cold air, salt, meat, and cold water. The umbilical cord

Containing fishing and family-oriented rafting, and paved bicycling and multi-use trails, it runs 30.6 miles (49.2 km) from Folsom Lake to the river's confluence with the Sacramento River. The American River Parkway incorporates historic Leidesdorff Ranch,

4560-480: The organization of descent, property customs also followed a patriarchal means. Women were also leaders through kinship, though not as commonplace as male leaders. Nisenan tribal families hold knowledge and memory of a shared society that was equally matriarchal|matrilineal in form and function. The Nisenan made two distinct living structure known as Hu , and K’um . Hu was the common structure in which villagers lived. These dome-shaped homes were typically built of

4636-644: The people of each region have distinct and unique customs and cultural practices. Although they have existed in these regions prior to European encounter, the people are not recognized as a tribe by the US government. The Nisenan previously had federal recognition via the Nevada City Rancheria . Some Nisenan people today are enrolled in the Shingle Springs Band of Miwok Indians , a federally recognized tribe . The name Nisenan derives from

They in turn traded black acorns, pine nuts, berries, animal skins, and wood needed to make bows As of 2020, about 147 Nisenan were residing in Nevada City, California. The tribe is not recognized by the government which prevents them from receiving federal protection and financial aid. Congress enacted the Rancheria Act of 1958 in an effort to disband

5396-453: The vast majority of wetlands have been converted to agriculture or urban areas. Most of the remaining wetland, riparian and aquatic ecosystems are restricted to the narrow corridor along the American River. There is an abundance of flora and fauna found at the American River that creates an immensely bio diverse ecosystem. Native plants along the American River Parkway are adapted to a Mediterranean climate, are drought tolerant, and help support
