<br />National Park will be above the minimum release objective during the summer months. To protect <br />both the blue ribbon trout fishery in the Black Canyon and recreational interests, releases during <br />2003 will be planned to minimize large fluctuations in the daily and monthly flows in the Gunnison <br />River below the Gunnison Tunnel diversion. <br /> <br />Under the minimum probable and most probable inflow scenarios, Blue Mesa Reservoir is not <br />expected to fill in the summer of2003. With the most probable inflow, Blue Mesa Reservoir will fill <br />to within about 12 feet of full pool in July 2003. <br /> <br />Navajo Reservoir <br /> <br />Exceptional drought conditions prevailed in the San Juan River basin in 2002 with extremely low <br />runoff in the basin. The April through July unregulated inflow into Navajo Reservoir in water year <br />2002 was 0.038 maf (46.9 mcm), or 4 percent of average. Water year 2002 unregulated inflow was <br />0.116 maf(143 mcm) or 10 percent of average. This inflow was significantly below the previously <br />recorded low, which occurred in 1977. The San Juan River basin is in an extended dry cycle. April <br />through July unregulated inflow to Navajo Reservoir in water years 1999, 2000, and 200 I was 81, <br />44, and 107 percent of average, respectively. Reservoir storage in Navajo Reservoir has been <br />significantly reduced due to these protracted drought conditions. Reservoir storage on September <br />30, 2002 was 51 percent of capacity. The water surface elevation at Navajo Reservoir on September <br />30,2002 was 6,015.6 feet (1,833.6 meters), 69.4 feet from full. <br /> <br />The final report titled Flow Recommendations for the San Juan River, (Flow Recommendations) <br />which outlines flow recommendations for the San Juan River below Navajo Dam, was completed by <br />the Biology Committee ofthe San Juan River Basin Recovery Implementation Program (SJRIP) in <br />May 1999. The report synthesizes research conducted on endangered fish in the San Juan River <br />over a 7 -year period. The purpose of the report is to provide flow recommendations for the San Juan <br />River that promote the recovery of the endangered Colorado pikeminnow and razorback sucker, <br />maintain important habitat for these two species, as well as the other native species, and provide <br />information for the evaluation of continued water development potential in the basin. It is <br />anticipated that implementation of the Flow Recommendations, or reasonable alternative to it, will <br />allow for a non-jeopardy biological opinion to be issued by the Service for the operations of Navajo <br />Dam. <br /> <br />Due to the severity of the drought and the hydrologic conditions in the San Juan River Basin during <br />the spring runoff period, the Flow Recommendations directed that no spring peak release was <br />necessary from Navajo Reservoir. Although there was no peak release, higher than normal base <br />flows were released from Navajo Reservoir during the spring and summer months during water year <br />2002. Releases from Navajo Reservoir reached 1,000 cfs (28 cms) during this period. These <br />increases were necessary due to decreasing flows in the San Juan River endangered fish critical <br />habitat area (Farmington to Lake Powell). The Flow Recommendations call for an average weekly <br />flow of between 500 cfs (14 cms) and 1,000 cfs (28 cms) in this reach of the river. <br /> <br />Reclamation has begun a National Environmental Policy Act (NEP A) process on the implementation <br />of an operation at Navajo Dam that meets these Flow Recommendations or a reasonable alternative <br />to them. A Notice of Intent to prepare an Environmental Impact Statement (EIS) was filed on <br /> <br />December 13,2002 <br /> <br />13 <br />
