How much lower will Trinity Lake be compared to recent years?
Potential changes to reservoir storage levels resulting from implementation of the Record of Decision (ROD) were modeled using the computer program CALSIM in the original Trinity River Restoration Program EIS/EIR, and updated for the draft SEIS/EIR and the Central Valley Project Operations Criteria and Plan (OCAP). As a result of implementing the ROD, it is projected that average end-of-water-year carryover storage would decrease by about 116,000 acre-feet (-8%). This equates to an average end of year lake elevation of 2286 ft. under current conditions compared to 2296 ft. prior to implementation of the ROD. This will vary depending on water year type and other factors described above. Refer to the attached diagram for more information.
