From email from Reclamation (Susan Novak Behery):

In response to wet weather and increasing flows in the critical habitat reach, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 650 cubic feet per second (cfs) to 500 cfs for today at 12:00 PM.

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.
