From email from Reclamation (Susan Novak Behery):

September 19, 2023

Due to the forecast for the coming week indicating sufficient flows in the critical habitat reach of the San Juan River, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 900 cubic feet per second (cfs) to 850 cfs for Wednesday September 20th, at 4:00 AM.

Reclamation continues to release project water to fulfill a project water release request by the Jicarilla Apache Nation’s subcontractors, The Nature Conservancy and the New Mexico Interstate Stream Commission, in addition to the normally scheduled release required to maintain the minimum downstream target baseflow.

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.
