<br />(0 <br />"',~ <br />(.;\J <br />...-l <br />,.7) <br />(~ <br /> <br />discussed followed by a description of the various center pivot and <br /> <br />corner budgets. This, in turn, is followed by a comparison and evaluation <br /> <br />of the various budgets. Finally, aonetary and non-monetary evaluations <br /> <br />of the various corner management alternatives are made. <br /> <br />The appendix 1 consists of a summary table of problems and net <br /> <br />returns. Appendix 2 consists of a set of 26-1977 center pivot and corner <br /> <br />budgets and six budgets representing 1974. The system of analysis used <br /> <br /> <br />for evaluating center pivot corners for wildlife habitat in the Colorado <br /> <br />Rio Grande Type IV River Basin Study is presented in appendix 3. Due to <br /> <br />the timeliness of the study, the year 1974 was established as a data <br /> <br />base year. The economics of center pivot irrigation and es,pecially <br /> <br />corner irrigation shifted between 1974 and 1977, mainly due to higher <br /> <br />costs and lower prices, but the analysis is presented in the appendix <br /> <br />in order to describe the procedures used. <br /> <br />Description of the Study Area <br /> <br />The study area consists of entire or parts of nine cotmties in <br /> <br />south central Colorado .botmded by the Rocky Motmtains and the Continental <br /> <br />Divide on the west, Sangre de Cristo Mountain Range on the east and the <br /> <br />state of New Mexico on the south. Elevations range from 7,500 feet on <br /> <br />the valley floor to over 14,000 feet on the mountain peaks. The valley <br /> <br />floor is relatively flat and is characterized by a low rise which divides <br /> <br />the Rio Grande drainage area from the Closed Basin. Winters are extremely <br /> <br />cold and the growing season is short. <br /> <br />The state and private non-urban portion of the study area comprises <br /> <br />about 2.4 million acres. Irrigated land comprises about 610,000 acres, <br /> <br />- 5 - <br />
