Dam Safety and Climate Resilience Local Assistance

Approximately 10 percent of the 1,236 State jurisdictional dams regulated by DWR’s Division of Safety of Dams (DSOD) have been assigned a condition assessment classification of less than “Satisfactory” (e.g., they have noted deficiencies that need remediation). In many cases, these dams pose a significant threat to communities downstream. As an interim risk reduction measure, more than 40 of these dams have had reservoir restrictions imposed. The loss of water storage from these reservoir restrictions is about 350,000 acre-feet.
