Good afternoon,

 

Below are planned releases from HHWP facilities through April 23^rd.

 

For permitting and access information contact the Groveland Ranger District.

 

We strive to keep the user community updated on projected flows on the Tuolumne River. Flows will continue to vary significantly over the coming weeks as weather changes and spring runoff season begins.

 

Stated flow rates are best estimates and are subject to change as conditions and operational constraints evolve.

• Additional releases may be possible pending inflows and operational conditions; notifications to be provided as needed.

Cherry Reservoir
