Shasta Lake,also popularly known asLake Shasta,[1]is areservoirinShasta County, California,United States. It began to store water in 1944[2]due to the impounding of theSacramento RiverbyShasta Dam,the ninth tallest dam in the United States.[3]

Shasta Lake is a key facility of theCentral Valley Projectand provides flood control for theSacramento Valleydownstream of the dam. Water outflow generates power through the Shasta Powerplant[4]and is subsequently used forirrigationand municipal purposes.[5]
The reservoir lies within theWhiskeytown–Shasta–Trinity National Recreation Area,operated by theShasta-Trinity National Forest.TheCalifornia Office of Environmental Health Hazard Assessment(OEHHA) has developed a safe eating advisory for fish caught in the lake based on levels of mercury orPCBsfound in local species.[6]
The Shasta-Keswick Reservoir system is significantly contaminated with heavy metals, primarily due to contributions from four streams.[7]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.[7]
Geography
editWith a capacity of 4,552,000 acre⋅ft (5.615 km3) at full pool, the lake has anelevationof 1,067 ft (325 m), and asurface areaof 30,000 acres (12,000 ha), making it the state's largestreservoir,and its third-largest body of water afterLake Tahoeand theSalton Sea.
Ten miles (16 km) north of the city ofRedding,with the town ofLakeheadon its northern shore, Shasta Lake is popular forboating,water skiing,camping, house boating and fishing. Formed by the damming of theSacramento River,the lake has 365 mi (587 km) of mostly steep mountainous shoreline covered with tall evergreen trees andmanzanita.The maximum depth is 517 feet (158 m).
The lake has four major arms, each created by an approaching river: theSacramento River,theMcCloud River,Sulanharas Creek,and thePit River.The Sacramento River's source is theKlamath Mountains.The McCloud River's source isMount Shasta.The Pit River flows fromAlturas,and the waterfall Potem Falls is located on that arm of the lake.
History
editShasta Damwas constructed between 1935 and 1945 across theSacramento River,and Shasta Lake was formed in 1948. ThePit River,McCloud River,and several smallertributarieshad their lower courses andconfluenceswith the Sacramento River submerged by the reservoir. Also beneath the lake is the submerged town ofKennettand many village sites of theWintun peopletogether with their traditional fishing, hunting, and gathering locations. Parts of the defunct tunnels and right of way of theSouthern Pacific Transportation Companycan 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 toClear 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.
