Current Restoration Flow Release Schedule

You may subscribe to our Automated Flow Release Notifications. Actual releases may not always follow the flow schedule – see our Flow FAQ page for details.


Water Year 2017 is an “Extremely Wet” year for Trinity River flows as determined by the April first reservoir inflow forecast of 2,265,000 acre feet, which allocates 815,000 acre feet of water for release to the river under the Record of Decision. The graphic below represents the restoration flow release as recommended by the Trinity Management Council. Read more on the 2017 flow release here.

Based on early water year forecasts in February and March, technical representatives of the Trinity River Restoration Program and program partners develop flow release recommendations to meet various restoration objectives and management targets listed in Chapter 8 of the Trinity River Flow Evaluation Final Report [PDF – 10mb]. Deliberations start with the typical flow release schedule recommended in the Record of Decision that may be adapted to meet specific restoration needs for the current year.

The flow recommendations are then presented to the Trinity Adaptive Management Working Group (TAMWG) and the Trinity Management Council (TMC) in March or early April for consideration. A ‘summary of water conditions’ as of April 1st of the year, is published by the California Department of Water Resources on or about April 10; this includes a forecast of reservoir inflow for the water year, known as the ‘b120 forecast’, which establishes the water year type and volume for restoration of the Trinity River. The flow release recommendation approved by the TMC is then forwarded to the U.S. Bureau of Reclamation and U.S. Fish and Wildlife Service as CVPIA co-lead agencies for the U.S. Department of Interior, which has the final authority over dam releases.
