The California Data Exchange Center site from the California Department of Water Resources provides the current water level at Shasta Lake. The ShastaLake.com website also posts the current water level and other lake information.
The Shasta Lake site lists the full lake level, at the crest of Shasta Dam, as 1067 feet. Both sites also post the lake water storage level, outflow, inflow and historical water level information. The postings are updated hourly. Shasta Lake is a reservoir and a site for fishing, boating and other outdoor activities. Its water level is controlled by Shasta Dam, and Keswick Dam is downstream.
