From email from Reclamation (Susan Behery):

In response to decreasing flows and a continued dry forecast weather pattern in the San Juan River Basin, the Bureau of Reclamation has scheduled an increase in the release from Navajo Dam from 900 cubic feet per second (cfs) to 1,000 cfs on Friday, August 14th, starting at 5:00 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 has recommended flows in the critical habitat reach as close to 500 cfs as possible for the summer of 2020. This is within their normal recommended range of 500 to 1,000 cfs. This target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
