<br />. <br /> <br />. <br /> <br />. <br /> <br />O~1613 <br /> <br />IRRIGATION REPORT <br />TRINIDAD PROJECT, COLORAOO <br />(Corps of Engineers) <br /> <br />Supplement to Appendix A <br />"Water Supply and Utilization" <br /> <br />Appendix A of the Irrigation Report was completed in April 1961. <br />The study presented in Appendix A assumed equal sh~ring of the project <br />water supply. This concept was unacceptable to the board of the <br />Purgatoire River Water Conservancy District. The board took the <br />position that operations should be modified to recognize and give <br />some advantage to those individuals presently holding the most senior <br />water rights and the Model Land and Irrigation Company which was pro- <br />viding the storage right. The district board, therefore, requested <br />that the operations reflected in the study be modified to: <br /> <br />(1) Permit the water rights owners within the district <br />to exercise their individual priorities when the <br />stored water had been depleted. <br /> <br />(2) Permit the Model Land and Irrigation Company to <br />reserve for their exclusive use 6,000 acre-feet <br />of the 20,000 acre-foot irrigation space. <br /> <br />(3) Provide a yield from this 6,000 acre-foot reser- <br />'vation approximating their historic yield by <br />allocating one-third of the nonirrigation season <br />storable flow and all irrigation season reservoir <br />inflows in excess of 300 c.f.s. storable under <br />Model right to the Model Account. <br /> <br />(4) Permit the Model Land and Irrigation Company to <br />share proportionately in the Project Account <br />after the Model Account has been reduced to 1,200 <br />acre-feet. The remaining 1,200 acre-feet is used <br />when the Project Account is empty and the District <br />is back on water right priorities. <br /> <br />The request resulted in the development of detailed operating <br />principles and criteria and revisions of the water supply and water <br />utilization studies presented in Appendix A, April 1961. <br />
