Another increase tonight at 11:00 pm to adjust for the quickly falling flows. The increase from earlier this week hasn't made it there yet (we should see a rise in the Bluff gage within a few hours), and this new release won't make it down there until after the weekend. Expect low average daily flows (in the 400s) through the Canyon for the next several days, unless the forecast rainstorm materializes.

NAVAJO RESERVOIR RELEASES
SENT VIA FAX AND E-MAIL
July 25, 2014
As a result of decreasing river flows in the San Juan River Basin, the Bureau of Reclamation has scheduled an increase in the release from Navajo Reservoir from 500 to 600 cubic feet per second (cfs) tonight, Friday, July 25th beginning at 11:00 p.m. 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.
This scheduled release change is subject to changes in river flows and weather conditions. If you have any questions, please contact Susan Behery at 970-385-6560 or email at email@example.com
