TRINITY & LEWISTON DAM OPERATIONS CHANGE ORDER - Dec. 31, 2024

TRINITY & LEWISTON DAM OPERATIONS CHANGE ORDER

Dec. 31, 2024

The Bureau of Reclamation's Central Valley Operations Office has released a change order notification for flows from Trinity and Lewiston Dams today, December 31. Due to a combination of low water diversions in 2024 and significant recent precipitation, current storage in Trinity Reservoir sits at 124% of average (74% of total capacity) and requires the release of additional flow to the Trinity River to absorb future winter storms.

We are advised that given the time of year and since inflows to Trinity Reservoir have reached storage management thresholds, it is reasonable to assume that flows to the Trinity River will remain elevated above 300 cubic feet per second for the foreseeable future, and that further hydrological events could warrant additional action from Central Valley Operations.

The change order was released as the following:

REVISION to TRRP Synchronization Flow Releases

Please make the following release changes at Trinity Dam:

             date                         time                       from (cfs)                  to (cfs)

12/31/2024	1600	1700	1600
1/1/2025	0001	1600	1500

Note:  remainder of Synchronization flow ramp down is canceled to manage Trinity Storage levels.
