From The Pagosa Springs Sun (Clayton Chaney):
After a recent storm that dropped nearly 2 feet of snow across the southern San Juan Mountains, the San Juan River has seen a rise in its flow rate compared to recent readings. Last month, a record low flow rate was set.
According to the U.S. Geological Survey, the San Juan River was flowing at a rate of 48.4 cfs as of 3 p.m. on Tuesday, Nov. 3.
Based on 84 years of water records, the river is still flowing below the average rate of 117 cfs for this date. The highest recorded rate for this date was in 1987 at 657 cfs. The lowest recorded rate was 22 cfs, recorded in 1956.
From email from Reclamation (Susan Novak Behery):
In response to increasing tributary flows, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 400 cubic feet per second (cfs) to 300 cfs on Monday, November 9th, starting 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.
