<br /> <br />The 175,000 shortage with Weld County is distributed: <br />68,000 above the reservoir site; zero between the sites, and <br />107,000 belo'" the site. With Narrows the 187,000 acre -f<i!et <br />shortage is distributed 69,000 above Weld County, 17,000 between <br />the sites and lOl,OOO acre-feet below Narrows site. <br /> <br />The results of our studies also show the following: <br /> <br />Results of U. S. Bureau of Reclamation <br />Narrows Unit Site Selection Study <br /> <br />1990 '1'ime Level <br /> <br />1. Additional water below Denver metro1>olitan area, <br />160,000 acre-feet. <br /> <br />2. There is sufficient demand below either the Weld <br />County or Narrows site to use all water developed. <br /> <br />3. The Weld County site reduces valley shortages <br />9,000 acre-feet more than Narrows without <br />additional facilities upstream, and 13,000 <br />acre-feet more with additional facilities. <br /> <br />~. The benefits from controlling floods from Bijou <br />Creek are $~4,000 annually. This is not enough <br />to justify the costs of controlling Bijou Creek <br />with either site. <br /> <br />5. The irrigated acreage inundated by Narrows without <br />controlling Bijou Creek are less than those <br />inundated by the Weld County Site. However, the <br />cropped lands inundated by Narrows are about <br />1800 acres greater and the irrigated meadow lands <br />are much less. <br /> <br />6. The Weld County site fully meets the demands of <br />the Riverside and Bijou ditches and all other <br />ditches from the reservoir to, but not including <br />the North Sterling ditch. <br /> <br />7. The Narrows site can exchange 22,000 acre-feet <br />upstream to meet shortages. Seven-thousand' <br />acre-feet of this amount could be exchanged only <br />to the Riverside and Bijou headgates. The <br />remainder can be exchanged this far or on upstream <br />to the Burlington headgate. <br /> <br />6 <br />
