Thus, all salvaged water would <br />be collected in the main channel about a mile north of U. S. Highway <br />No. 160. <br /> <br />About 129 wells and pumps and 92 miles of lateral canals would be <br />constructed to carry the salvaged water to Saguache Creek, the main <br />conveyance channel, and the San Luis Lake Channel. The laterals <br />would vary in capacity from 0.6 second-foot to 20 second-feet. There <br />would be no wel Is along the main channel below San Luis Lake to the <br />Rio Grande. <br /> <br />Temperature of pumped ground water has been measured at 520 F. Cold <br />nights throughout the year would prevent appreciable warming of the <br />salvaged water and it is estimated that maximum temperatures in the <br />main channel would be about 620 F. Ponded or impounded water in San <br />Luis Lake probably would reach a maximum of 720 F. on a few days each <br />year. Low readings of minus 300 F. are recorded in most years. It <br />is anticipated that the surface of the channels would be frozen most <br />of the winter. <br /> <br />Historically the water surface of San Luis Lake has varied consid- <br />erably due to drought. With an equalizing channel constructed be- <br />tween the lake and the main channel, the water surface of San Luis <br />Lake would be controlled by the water surface elevation in the main <br />channel. Under normal discharge conditions San Luis Lake would <br />have a surface area of about 860 acres. For brief periods of time <br />when the main channel would be flowing at maximum design capacity <br />the water surface elevation would increase about 1.8 feet and the <br />area of San Luis Lake would increase to 900 acres. <br /> <br />The period of analysis for fish and wildlife coincides with the <br />projected life of the project, 100 years. <br /> <br />FISH <br /> <br />Without the Project <br /> <br />The area of influence of the project on fish includes San Luis Lake, <br />32 miles of the Rio Grande in Colorado, and 76 miles of the Rio <br />Grande in New Mexico. <br /> <br />Due to its fluctuating water level, San Luis .Lake provides mediocre <br />quality fishing and would support about 1,000 man-days annually. <br />
