Therefore, the water below and vegetation on top of land outside the Project boundaries should not be significantly affected by the operation of the Proj ect. Wells will be completed at depths from 65 to 125 feet in the unconfined (uppermost) aquifer. The yields on these wells are expected to vary from .75 to 2.25 cubic feet per second (cfs) (or 337 to 1010 gallons per minute). A turbine pump will deliver ground water from each well into a buried pipe system. The Project design calls for approximately 100 miles of pipe which will deliver the ground water to the primary conveyance channel. The conveyance channel transports the salvaged water into the Rio Grande mainstern southeast of the town of Alamosa, Colorado (below the diversion dam for the New Ditch). This conveyance channel is approximately 42 miles long, varies from 8 to 22 feet in bottom width, 4.7 to 5.7 feet in depth, and is capable of carrying 20 to 160 cfs. The USBR estimates 66,000 to 104,000 acre-feet of ground water will be pumped annually. The water delivered by the Closed Basin Project is categorized by the uses of the water as described below. Priority One diversions are those made to assist the State of Colorado in meeting its commitments to the States of New Mexico and Texas as required by the Rio Grande Compact. Priority Two diversions are made to enhance wildlife in the Alamosa National Wildlife Refuge and Blanca Wildlife Habitat Area. Priority Three diversions are available at a charge for general use by Rio Grande and Conejos water users after Priority One and Priority Two uses have been satisfied. Priority Three water (as defined in this study) was labeled as Priority Four water in the authorizing legislation for the Closed Basin Project. 37
