From email from Reclamation (Susan Novak Behery):
August 21, 2023
The precipitation that was forecast did not materialize this weekend, and the coming forecast precipitation has been reduced. For that reason, the Bureau of Reclamation has scheduled an increase in the release from Navajo Dam back to 700 cubic feet per second (cfs) from 600 cfs for tomorrow, August 22nd, at 4:00 AM.
Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell). The San Juan River Basin Recovery Implementation Program recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area. The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
