From email from Reclamation (Susan Novak Behery):

September 1, 2023

The upcoming forecast is warmer and drier than average, and forecast flows in the critical habitat reach are steadily decreasing. For this reason, the Bureau of Reclamation has scheduled an increase in the release from Navajo Dam to 800 cubic feet per second (cfs) for tomorrow, September 2nd, 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.
