Shasta Lake, also popularly known as Lake Shasta, is a reservoir in Shasta County, California, United States. It began to store water in 1944 due to the impounding of the Sacramento River by Shasta Dam, the ninth tallest dam in the United States.
Shasta Lake is a key facility of the Central Valley Project and provides flood control for the Sacramento Valley downstream of the dam. Water outflow generates power through the Shasta Powerplant and is subsequently used for irrigation and municipal purposes.
The reservoir lies within the Whiskeytown–Shasta–Trinity National Recreation Area, operated by the Shasta-Trinity National Forest. The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for fish caught in the lake based on levels of mercury or PCBs found in local species.
The Shasta-Keswick Reservoir system is significantly contaminated with heavy metals, primarily due to contributions from four streams. Three of these streams contain acid mine drainage, with Spring Creek being the most notable contributor. This drainage releases high concentrations of zinc, cadmium, and copper into the water. At the points where these acid streams mix with lake water, localized toxicity occurs, posing an immediate threat to aquatic life. The synergistic effects of these metals further exacerbate the environmental impact, leading to concerns about the safety of consuming fish from this water source.




Geography


With a capacity of 4,552,000 acre⋅ft (5.615 km3) at full pool, the lake has an elevation of 1,067 ft (325 m), and a surface area of 30,000 acres (12,000 ha), making it the state's largest reservoir, and its third-largest body of water after Lake Tahoe and the Salton Sea.
Ten miles (16 km) north of the city of Redding, with the town of Lakehead on its northern shore, Shasta Lake is popular for boating, water skiing, camping, house boating and fishing. Formed by the damming of the Sacramento River, the lake has 365 mi (587 km) of mostly steep mountainous shoreline covered with tall evergreen trees and manzanita. The maximum depth is 517 feet (158 m).
The lake has four major arms, each created by an approaching river: the Sacramento River, the McCloud River, Sulanharas Creek, and the Pit River. The Sacramento River's source is the Klamath Mountains. The McCloud River's source is Mount Shasta. The Pit River flows from Alturas, and the waterfall Potem Falls is located on that arm of the lake.




History


Shasta Dam was constructed between 1935 and 1945 across the Sacramento River, and Shasta Lake was formed in 1948. The Pit River, McCloud River, and several smaller tributaries had their lower courses and confluences with the Sacramento River submerged by the reservoir. Also beneath the lake is the submerged town of Kennett and many village sites of the Wintun people together with their traditional fishing, hunting, and gathering locations. Parts of the defunct tunnels and right of way of the Southern Pacific Transportation Company can be seen when the water level is low.
Shasta Lake hosted the first "Boardstock" event in 1996, which continued there annually through 1999, after which the annual event moved to Clear Lake, California, 170 miles southwest of Shasta Lake. Boardstock drew many professional wakeboard riders from around the world, with an average attendance of 15,000 people. The event lasted for 3 days each year with several wakeboard contests being performed.
