Sufficient water would be released downstream <br />to maintain a fishery in the Animas River below the diversion. The <br />environmental impact of irrigation will be minor as most lands in the <br />project are either presently irrigated or dryfarmed. There may be some <br />increases of salinity in the Colorado River from irrigation and M&I use <br />of water by the project. Secondary effects of providing water for <br />private developments, such as a thermal powerplant in the area, will <br />need to be determined and remedial measures identified to reduce <br />pollution. <br /> <br />Current Status <br /> <br />Advance planning studies were initiated in F.Y. 1971 with funds <br />contributed by the state of Colorado and local water user organizations. <br />Federal funds in the amount of $225,000 were appropriated in F.Y. 1971 <br />and placed in budgetary reserve. These funds were released for use in <br />F.Y. 1972. <br /> <br />Feasibility and advance planning costs to June 30, 1974 amount to <br />$1,880,934. <br /> <br />Present advance planning activities include a comprehensive <br />reevaluation-of-the plan as formulated in the authorizing report~, A <br />reassessment of 'the area!s ,needs is also being made. Attempts are <br />being made to reassess water requirements for the communities of Durango. <br />Aztec and Farmington. Water deliveries planned for Indian resource <br />developments are being revised. The definite plan report is scheduled <br />for completion by July. 1976. <br /> <br />-3- <br /> <br />I <br />
