Media Contact: Pete Lucero, 916 978-5100

For Release: April 19, 2011

The Bureau of Reclamation today announced the schedule for high-flow releases from Lewiston Dam into the Trinity River as part of the Trinity River Restoration Program. The official water year designation for the Trinity River is "wet." The water allocation for restoration-related flow releases associated with a wet water year is 701,000 acre-feet.

The flow releases will begin increasing on April 22, 2011, reaching a peak release of 11,000 cubic feet per second (cfs) on May 4. These peak flows will be held for a period of three days and then decreased to 4,500 cfs by May 9. After that date, releases will be gradually decreased to a 450 cfs summer base-flow on August 1. Near the end of August, there will be a moderate increase in releases for about a week for Native American ceremonial purposes.

The public should take appropriate safety precautions whenever river flows are high. Landowners are advised to clear personal items and debris from the floodplain prior to the releases.

A daily schedule of flow releases is available at: At this website, the public may subscribe to automated notifications (via phone or email) of Trinity River release changes.
