The Trinity Management Council has recommended that flow releases from Lewiston Dam to the Trinity River begin on Sunday, April 14, following the wet water year designation for 2019. 

Under the recommendation, the peak will reach approximately 11,000 cfs on April 29, with smaller peaks of 10,000 cfs on April 17 and 7,200 cfs on May 18. The final schedule is expected to be approved by April 12.

People residing near the river or recreating on the river can expect river levels to rise and should take appropriate safety precautions. Landowners are advised to move personal items away from the river prior to the flow releases.

Flows will begin ramping down by June 24 until the summer baseflow of 450 cfs is reached on Aug. 5. Releases for a “wet” water year will result in an annual total volume of 701,000 acre-feet.

The December 2000 Trinity River Mainstem Fishery Restoration Record of Decision created a plan for the restoration of the Trinity River and its fish and wildlife populations. More information on the Trinity River ROD can be found at

The water year designation is determined by California Department of Water Resources, and generally announced around mid-April.

Once approved, a daily flow release schedule will be available at and the public may subscribe to automated notifications (via phone or email) of Trinity River release changes. The flow release schedule will also be posted at the Trinity River Restoration Program office, located at 1313 South Main St., Weaverville.

This Thursday, April 11, the Trinity River Restoration Program will host a public information meeting on the recommended releases and gravel augmentation plans for the Trinity River. The meeting will be held from 6 to 7:30 p.m. at the TRRP office at the above address.
