The specific <br />location to which the returns will occur is dependent upon the level of development of Blocks 1 <br />through 11, During the CROSS study period (1975 through 1991), the locations of the return <br />flows from the NIIP (Blocks 1 - 7) are estimated as follows: <br /> <br />1. Above USGS Gage 09365000 (San Juan at Farmington) 45% <br />2. Above Diversion for San Juan Power Plant 35% <br />3. Above USGS Gage 09379500 (San Juan at Bluff) 20% <br /> <br />After full development of the remaining NIIP Blocks 8 - 11. the pattern of return flows will <br />shift as follows: <br /> <br />1. Above USGS Gage 09365000 (San Juan at Farmington) 40% <br />2. Above Diversion for San Juan Power Plant 30% <br />3. Above USGS Gage 09379500 (San Juan at Bluff) 30% <br /> <br />San Juan Power Plant <br /> <br />The San Juan Power Plant is'operated by Public Service of New Mexico (PNM) and is <br />located on the north side of the San Juan River about 13 miles west of Farmington. The facility <br />includes four coal-fired generation units with a capacity of 1,780 net megawatts. Water for the <br />operation of the plant is obtained pursuant to a 20-year contract (through year 2005) with the <br />USBR for storage water in Navajo Reservoir. The contract is for 16,200 acre-feet per year, which <br />closely matches the current water demand for the operation of the power plant. For purposes of <br />the CROSS WRPM, it is assumed that the annual demand of 16,200 acre-feet is evenly distributed <br />throughout the year (1,350 acre-feet per month). The diversion is 100% consumptive, with no <br />return flows to the San Juan River. These assumptions were confirmed with personnel at PNM. <br /> <br />As a back-up to the Navajo Reservoir storage contract, the San Juan Power Plant also has <br />a contract to lease an additional 8,000 acre-feet from Broken Hill Properties (BHP), the operator <br />of most of the coal mines in the area. This water derives from a permitted New Mexico water <br /> <br />23 <br />
