Keswick Reservoir

Reservoir Levels Weather Hydrology

Keswick Reservoir is located in northern California and is part of the Shasta-Trinity National Forest. It was constructed in the early 1950s as part of the Keswick Dam project, which aimed to provide hydroelectric power and irrigation water to the surrounding agricultural community. The reservoir is fed by the Sacramento River and several smaller tributaries, and its hydrology is influenced by both snowpack melt and surface flow. The snowpack is primarily provided by the nearby Trinity Alps, while surface flow is dependent on precipitation and runoff in the surrounding area. The reservoir is used for irrigation, but also serves as a popular recreational destination for fishing, boating, and swimming. However, in recent years, the reservoir has been impacted by drought, leading to decreased water levels and restrictions on recreational activities.
