Statement of Work <br />WATER ACTIVITY NAME - Animas River Needs Assessment <br />GRANT RECIPIENT - San Juan Resource Conservation and Development in partnership <br />with the Animas Watershed Partnership <br />FUNDING SOURCE - SW Roundtable <br />INTRODUCTION AND BACKGROUND <br />This project completes a watershed-wide study of the Animas River, identifying <br />sources of pollution in the Colorado portion of the watershed and impacted <br />riparian and thus assimilative capacity of the river and identifying methods to <br />mitigate or remediate the sources of pollution and improve the assimilative <br />capacity for the benefit of both consumptive and non-consumptive uses and to <br />protect beneficial and designated uses. A similar study has been completed in <br />the New Mexico portion of the watershed. <br />OBJfCTIVES <br />• Analysis of the chemical and biologicat communities of the Animas River <br />• Analysis of the geomorphic characteristics and degraded assimilative capacity <br />of the Animas River <br />• Identification of poltution sources on the Animas River <br />• Identification of opportunities to remediate and mitigate pollution sources on <br />the Animas River <br />TASKS <br />Task 1 - Water Quality <br />The existing water quality conditions of the tower basin of the Animas River in Colorado <br />and its inflows will be identified in this task. This will be accomplished through sampling <br />and anatyzing the water and biological communities in the Animas River immediately <br />upstream of each inflow as well as sampling and analyzing the water and biota from each <br />inflow. Sample sites will be identified by a reconnaissance where each inflow to the <br />Animas River (including pipes, field drains, natural drainages, and irrigation ditch return <br />flows) will be identified, photographed and mapped. The water quality of the Animas <br />upstream of each inflow represents the influence each surface flow has on the river. <br />1 <br />
