Estimating Shasta Lake Cold Water Supply to Help Sacramento River Salmon

Shasta Dam

SWFSC Fisheries Ecology Division researchers Eric Danner and Andrew Pike have developed a water temperature model for the Sacramento River which informs water and fisheries managers of how their operations at Shasta Dam will impact the downstream spawning and rearing habitat for ESA listed winter-run Chinook salmon. They are now coupling their river model with a reservoir model for Shasta Lake. The reservoir model will allow users to estimate the amount of the cold water available in the lake, both currently and under forecasted conditions. Once the river and reservoir models are linked together, they can be used to evaluate how various operating scenarios will impact both the downstream temperatures and the cold water resources in the lake over time.
