Release changes are made based on river conditions and coordination with federal, state, and local agencies.
The shape and timing of the hydrograph have been coordinated with the San Juan River Basin Recovery Implementation Program to balance Recovery Program benefits with flood control and operational safety. During spring operations, releases from the Navajo Unit will be made in an attempt to remain at or below the U.S. Army Corps of Engineers safe channel capacity of 5,000 cfs between Navajo Reservoir and the confluence with the Animas River in Farmington, and 12,000 cfs downstream of Farmington. The release may be changed or reduced if the precipitation forecast shows a risk of exceeding safe channel capacity in the San Juan River.
Areas in the immediate vicinity of the river channel may be unstable and dangerous. River crossing may change and be impassable as flows increase. Please use extra caution near the river channel and protect or remove any valuable property in these areas.

May 22, 2023
SENT VIA E-MAIL
High snowpack in the San Juan River Basin this year has led to an above-average inflow forecast into the Navajo Reservoir. The latest most probable inflow forecast from the Colorado Basin River Forecast Center has increased to 160% of average inflows due to snowmelt runoff from April through July.
The forecast now allows for a spring peak release as recommended by the San Juan River Basin Recovery Implementation Program (SJRIP). The release is currently ramping up and is scheduled to reach 5,000 cfs by this weekend. However please note that as this operation is entirely dependent on weather, inflows, and on-the-ground conditions, this schedule may change. The release is scheduled to remain at peak for 23 days. The previous schedule of 21 days has been amended by additional forecast supply and contractual obligations.
The next changes are shown hourly below. The full daily schedule is posted on our website and is updated as needed. https://www.usbr.gov/uc/wcao/water/rsvrs/notice/nav_rel.html
This operation is subject to changes in river flows and weather conditions and will be coordinated daily with local, state, and federal agencies to ensure objectives are met in a safe manner.

High snowpack in the San Juan River Basin this year has led to an above-average inflow forecast into the reservoir. The latest most probable inflow forecast from the Colorado River Basin Forecast Center is for 150% of average inflows from snowmelt runoff.
While most of the releases will be made to recover reservoir storage, Reclamation is planning to conduct a channel maintenance release from Navajo Dam. The release will ramp up slowly, peaking at 5,000 cfs for at least 11 days before ramping back down. This operation is expected to begin the last week of May and last through the third week of June. The exact schedule dates are to be determined as they will be timed to coincide with the peak on the Animas River. A notice with the final start date will be sent out approximately one week prior to beginning this release. Please stay tuned for updates.

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.
