<br />I <br /> <br />I <br /> <br />I <br /> <br />annual precipitation is 10.8 inches. The frost-free period is about <br />135 days per year on the average. <br /> <br />I <br /> <br />The temperature records maintained at the Crawford station, <br /> <br /> <br />located immediately to the north of the project area, show the extreme <br /> <br /> <br />temperatures of 930F and -250F. The average annual temperature is <br /> <br />45.60F. <br /> <br />I <br /> <br />I <br /> <br />B. Problems and Needs <br /> <br />I <br /> <br />The major problem, which is to be addressed in this study. is <br /> <br /> <br />inadequacy of irrigation supplies in the project area. The estimated <br /> <br /> <br />water shortages on the presently irrigated areas average about 33 <br /> <br /> <br />percent [2]. This estimate is also supported by the local farmers. <br /> <br /> <br />The available irrigation supplies are undependable. These factors <br /> <br /> <br />have caused the farmers and the ranchers to reduce cultivated areas by <br /> <br /> <br />concentrating water on fewer fields to meet the irrigation demands of <br /> <br /> <br />those areas fully. <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />The irrigation water shortage is further aggravated by the fact <br /> <br /> <br />that most of the water supply problems occur late in the irrigation <br /> <br /> <br />season when the crops are maturing and steady water applications are <br /> <br /> <br />required. The result is smaller crop yields and financial loss to the <br /> <br /> <br />farmers. <br /> <br />I <br /> <br />I <br /> <br />The need is, therefore, to make the best use of the available <br /> <br /> <br />sources of water--by diversion, by increasing storage capacity in the <br /> <br /> <br />system, and by improving the overall management of the land and water <br /> <br />I <br /> <br />I <br /> <br />resources. <br /> <br />I <br /> <br />According to the W.P.R.S. [2], the National Park Service and the <br /> <br /> <br />Bureau of Land Management have indicated their water need on the order <br /> <br /> <br />of 15 acre feet annually for public use at recreation facilities and <br /> <br /> <br />for livestock use on the lower Fruitland Mesa. <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I <br /> <br />I-7 <br />
