Grizzly Valley Dam is an earth-and-rock dam 800 feet (240 m) long and 115 feet (35 m) high, with 10 feet (3.0 m) of freeboard. The California Department of Water Resources manages the dam. [2]
Located in Plumas National Forest, Lake Davis is the centerpiece of the Lake Davis Recreation Area, which supports boating, campground camping, cross-country skiing, fishing, hunting, mountain biking, picnicking, snowmobiling, swimming, and wildlife viewing. [3]
During 1996-97 Lake Davis was in the national spotlight due to controversy over northern pike and the possibility of poisoning the lake. Following an explosion of the pike population, and the California Department of Fish and Game (DFG) decided to treat the reservoir with rotenone, a naturally occurring poison deadly to gilled creatures. [4]
After the first attempt failed to eradicate the pike and the population rebounded, the DFG again utilized rotenone in September 2007, after lowering the water level. [5] DFG's justification for the action was their concern that pike might escape the lake and enter the Sacramento River system, potentially harming native anadromous fish species such as steelhead and salmon. The effort was controversial because pike are popular gamefish and considerable effort had already been spent on unsuccessful attempts to rid the lake of pike using explosives, nets, shocking, and poison.
Since the 2007 treatment, there have been no confirmed cases of northern pike in the lake.
The Feather River is the principal tributary of the Sacramento River, in the Sacramento Valley of Northern California. The river's main stem is about 73 miles (117 km) long. Its length to its most distant headwater tributary is just over 210 miles (340 km). The main stem Feather River begins in Lake Oroville, where its four long tributary forks join—the South Fork, Middle Fork, North Fork, and West Branch Feather Rivers. These and other tributaries drain part of the northern Sierra Nevada, and the extreme southern Cascades, as well as a small portion of the Sacramento Valley. The total drainage basin is about 6,200 square miles (16,000 km2), with approximately 3,604 square miles (9,330 km2) above Lake Oroville.
Oroville Dam is an earthfill embankment dam on the Feather River east of the city of Oroville, California, in the Sierra Nevada foothills east of the Sacramento Valley. At 770 feet (235 m) high, it is the tallest dam in the U.S. and serves mainly for water supply, hydroelectricity generation, and flood control. The dam impounds Lake Oroville, the second-largest man-made lake in California, capable of storing more than 3.5×10 6 acre⋅ft.
Lake Oroville is a reservoir formed by the Oroville Dam impounding the Feather River, located in Butte County, northern California. The lake is situated 5 miles (8.0 km) northeast of the city of Oroville, within the Lake Oroville State Recreation Area, in the western foothills of the Sierra Nevada. Known as the second-largest reservoir in California, Lake Oroville is treated as a keystone facility within the California State Water Project by storing water, providing flood control, recreation, freshwater releases assist in controlling the salinity intrusion into the Sacramento-San Joaquin Delta and protecting fish and wildlife.
Don Pedro Reservoir, also known as Lake Don Pedro, is a reservoir formed by the construction of the New Don Pedro Dam across the Tuolumne River in Tuolumne County, California, United States.
Trinity Dam is an earthfill dam on the Trinity River located about 7 miles (11 km) northeast of Weaverville, California in the United States. The dam was completed in the early 1960s as part of the federal Central Valley Project to provide irrigation water to the arid San Joaquin Valley.
The San Luis Reservoir is an artificial lake on San Luis Creek in the eastern slopes of the Diablo Range of Merced County, California, approximately 12 mi (19 km) west of Los Banos on State Route 152, which crosses Pacheco Pass and runs along its north shore. It is the fifth largest reservoir in California. The reservoir stores water taken from the San Joaquin-Sacramento River Delta. Water is pumped uphill into the reservoir from the O'Neill Forebay which is fed by the California Aqueduct and is released back into the forebay to continue downstream along the aqueduct as needed for farm irrigation and other uses. Depending on water levels, the reservoir is approximately nine miles long from north to south at its longest point, and five miles (8 km) wide. At the eastern end of the reservoir is the San Luis Dam, or the B.F. Sisk Dam, the fourth largest embankment dam in the United States, which allows for a total capacity of 2,041,000 acre-feet (2,518,000 dam3). Pacheco State Park lies along its western shores.
The California State Water Project, commonly known as the SWP, is a state water management project in the U.S. state of California under the supervision of the California Department of Water Resources. The SWP is one of the largest public water and power utilities in the world, providing drinking water for more than 23 million people and generating an average of 6,500 GWh of hydroelectricity annually. However, as it is the largest single consumer of power in the state itself, it has a net usage of 5,100 GWh.
Lake Almanor is a large reservoir in northwestern Plumas County, northeastern California, United States. The reservoir has a capacity of 1,308,000 acre-feet (1.613×109 m3) and a maximum depth of about 90 feet (27 meters). It is formed by Canyon Dam on the North Fork of the Feather River, as well as Benner and Last Chance Creeks, Hamilton Branch, and various natural springs.
Frenchman Lake(a.k.a. Frenchmen's Reservoir and several derivations thereof) is located in Southeastern Plumas County, California and was created by the damming of Little Last Chance Creek. It was named after Frenchman Creek and Claude Francois Seltier, a French immigrant who settled in the area in 1858.
Lake Pillsbury is a lake in the Mendocino National Forest of Lake County, California, created from the Eel River and Hull Mountain watershed by Scott Dam. Elevation is 1,818 ft (554 m) with 65 mi (105 km) of shoreline and covering 2,003 acres (811 ha). Activities in the Lake Pillsbury Recreation Area include powerboating, fishing, swimming, sailing, picnicking, hiking and hang gliding. There are two main access roads to the lake. At the north end of the lake is a small gravel airstrip. Over 400 homes including National Forest Recreational Residences ring the lake.
McGregor Lake is an elongated reservoir in Southern Alberta. McGregor Lake was created in 1920 by the completion of two dams bracketing water flowing through in Snake Valley. It is situated 100 km (62 mi) southeast of Calgary in the Vulcan County.
The Middle Fork Feather River is a major river in Plumas and Butte Counties in the U.S. state of California. Nearly 100 miles (160 km) long, it drains about 1,062 square miles (2,750 km2) of the rugged northern Sierra Nevada range.

Nacimiento Dam is a dam on the Nacimiento River about 10 miles (16 km) northwest of Paso Robles, California in the United States. The primary purpose of the dam is to provide groundwater recharge for agriculture in Monterey County and northern San Luis Obispo County supported by the Salinas Valley aquifer, as well as flood control, domestic water supply, and hydropower. It forms Lake Nacimiento, popular for boating, fishing and camping, and known locally as the "Dragon Lake" due to its shape.
