CASE STUDY - LAKE SHASTA, CA

LAKE SHASTA, CALIFORNIA

Shasta Dam is located about 9 miles NW of Redding, California, on the Sacramento River. Built between 1938 and 1945, the dam is a 602-foot-high concrete gravity dam, which provides flood control, power, and water supply benefits. The reservoir is also used extensively for recreation.

Shasta Dam and Shasta Reservoir are key facilities in the Central Valley Project. Shasta Reservoir is fed by the Sacramento, Pit, and McCloud rivers, with additional water coming from Squaw Creek. This drainage area receives an average of 62 inches of annual precipitation, which in pre-dam years was a major contributor to frequent floods in the valley below. Water released to the river is sent through the Shasta Powerplant, which produces hydroelectric power for the 15-state western power grid.

Lake Shasta has populations of invasive New Zealand Mud Snails. The Shasta-Trinity National Forest has quagga/zebra mussel alerts for Shasta Lakes because of the proximity of these species in other California lakes.

Local governments have the authority to regulate and determine their own municipal affairs. Cities and counties exercise a broad affair of powers unless specifically prohibited or preempted by the State legislature.
