As a result of increasing river flows in the San Juan River Basin, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Reservoir from 600 cubic feet per second (cfs) to 500 cfs tonight, Wednesday, August 24th starting at 11:00 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. 
 

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 sbehery@usbr.gov.

August 23rd 1pm: Navajo Operations August Coordination Meeting

This meeting is held three times annually to discuss the upcoming forecast and operations for the coming water year and beyond.  The meeting agenda will include a review of operations and hydrology since April, current soil and water supply conditions, a discussion of hydrologic forecasts and planned operations for the remainder of this water year as well as planned operations for water year 2017, updates on maintenance activities, and the Recovery Program on the San Juan River.  Additionally there will be short presentations from the US Army Corps of Engineers and Reclamation’s Technical Service Center on the channel hydraulics and capacity downstream of the dam.

August 23rd 6pm: Navajo Reservoir 2016 Spring Peak Release Operations

This is a special meeting geared towards discussion of this year’s Spring Peak Release. The agenda will include a recap of 2016 Spring Peak Operations, a discussion of flood risk management and safe channel capacity, the nature of sedimentation and bank erosion in the San Juan River Basin, and floodplain risk issues.  The meeting will include talks and representation from several agencies, including Reclamation, US Army Corps of Engineers, Fish and Wildlife Service, and San Juan County, New Mexico, Office of Emergency Management.  There will be opportunities for questions, comments, and discussion with the public during the meeting.

2016 SPRING PEAK RELEASE UPDATE

June 30, 2016

SENT VIA FAX AND E-MAIL

Reclamation will begin ramping down the release from Navajo Reservoir beginning tomorrow, Friday, July 1st. Ramp down will be 12-days long, ending at a release of 500 cubic feet per second (cfs) on July 12th. Following ramp down, releases will be made to maintain the recommended target base flow in the critical habitat reach. While flows are still high, areas in the immediate vicinity of the river channel may be unstable and dangerous. Please use extra caution near the river channel and protect and/or remove any valuable property in these areas.

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 Dam and the confluence with the Animas River in Farmington, and 12,000 cfs downstream of Farmington. The release may be changed or reduced if precipitation forecasts show risk of exceeding safe channel capacity in the San Juan River San Juan River.

SENT VIA FAX AND E-MAIL

The Bureau of Reclamation has finalized this year's scheduled spring peak release from Navajo Reservoir. The attached chart shows the end of day release rates throughout the spring peak release period. Reclamation will begin to increase the release on Wednesday, May 18th, 2016 at 1:00 AM, reaching 5,000 cubic feet per second (cfs) on Sunday, May 22nd at approximately 11:00 AM. The release will stay at 5,000 cfs for up to 31 days, or until the spring runoff on the Animas River is complete. If all 31 days at peak are utilized, the release will begin decreasing on Thursday, June 23rd at approximately 9:00 AM, reaching 500 cfs on Monday, July 4th at approximately 4:00 AM, where it will remain until further notice.

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 potential flood control and operational safety. During spring operations, releases from the Navajo Unit will be made in an attempt remain at or below the U.S. Army Corps of Engineers safe channel capacity of 5,000 cfs between Navajo and the confluence with the Animas River in Farmington, and 12,000 cfs downstream of Farmington. The release may be changed or reduced if precipitation forecast show risk of exceeding safe channel capacity in the San Juan River.

BUREAU OF RECLAMATION
NAVAJO UNIT FORECAST FOR SPRING OPERATIONS
May 3, 2016

The May update to the most probable forecast for the April – July modified unregulated inflow volume to Navajo Reservoir is 520,000 acre-feet, an increase of 5,000 acre-feet since the last forecast. This is 71% of the 30 year average. Snowpack above Navajo is currently 76% of average. Navajo reservoir current content is 1,496,000 acre-feet, which is 88% full (80% of active storage). Current reservoir elevation is 6070.1 feet.

As per the 2016 Interim Operations at Navajo Reservoir, releases will be made to target the San Juan River Basin Recovery Implementation Program's (SJRIP) recommended baseflows 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. The reservoir will be operated to target an end of year storage level between 6050 feet and 6063 feet. Water over this target will be made available for a spring peak release.

The most probable forecast results in a spring peak release consisting of a 5-day ramp up to 5,000 cfs, up to 31 days at 5,000 cfs, followed by a 12-day ramp back down to the base release. The ramp-up date is dependent on weather, and will most likely be either May 16th (30% chance) or May 23 (70% chance). The final date will be decided one week before ramp-up begins.

The shape and timing of the hydrograph may change and will be coordinated with the SJRIP to balance recovery program benefits with potential flood control and operational safety. During spring operations, releases from the Navajo Unit will be made in an attempt to match the peak timing of the Animas River to maximize the peak at the San Juan at Four Corners gage while remaining below the US Army Corps of Engineers safe channel capacity of 5,000 cfs between Navajo and the confluence with the Animas in Farmington, and 12,000 cfs downstream of Farmington.

Projected spring operations will be updated with revisions to the forecast and are highly dependent on tributary flows throughout the San Juan River Basin.

NAVAJO UNIT FORECAST FOR SPRING OPERATIONS
April 18, 2016

The mid-April update to the most probable forecast for the April – July modified unregulated inflow volume to Navajo Reservoir is 515,000 acre-feet, a decrease of 15,000 acre-feet since the last forecast. This is 70% of the 30 year average. Snowpack above Navajo is currently 80% of average. Navajo reservoir current content is 1,475,000 acre-feet, which is 87% full (78% of active storage). Current reservoir elevation is 6069.5 feet.

As per the 2016 Interim Operations at Navajo Reservoir, releases will be made to target the San Juan River Basin Recovery Implementation Program's (SJRIP) recommended baseflows 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. The reservoir will be operated to target an end of year storage level between 6050 feet and 6063 feet. Water over this target will be made available for a spring peak release.

The most probable forecast results in spring peak release beginning in mid-May with a short 3-day ramp up to 5,000 cfs, 31 days at 5,000 cfs, followed by a 2-week ramp back down to the base release. The shape and timing of the hydrograph may change and will be coordinated with the SJRIP to balance recovery program benefits with potential flood control and operational safety. During spring operations, releases from the Navajo Unit will be made in an attempt to match the peak timing of the Animas River to maximize the peak at the San Juan at Four Corners gage while remaining below the US Army Corps of Engineers safe channel capacity of 5,000 cfs between Navajo and the confluence with the Animas in Farmington, and 12,000 cfs downstream of Farmington.

Projected spring operations will be updated with revisions to the forecast and are highly dependent on tributary flows throughout the San Juan River Basin.
