[' , , Exhibit A Grant for Proposed Feasibility Study of Long Hollow Reservoir and Red Mesa Reservoir Enlargement . . r r'~ ! Study Objective The objective of this study is to investigate the technical, financial and institutional aspects of a limited number of alternative darn and reservoir configurations to increase the Reservoir's capacity to approximately 4,000 AF. The need for enlargement of this facility was established in previous studies (Western La Plata County Water Management and Conservation Plan, Red Mesa Reservoir Enlargement: Feasibility Study). Enlargement of the Reservoir will improve the currently inadequate water supplies in the basin, particularly if the enlargement is constructed as part of a plan that also includes Long Hollow Darn and Reservoir. Before the Long Hollow Reservoir is constructed, enlargement of the Red Mesa Reservoir could help to improve La Plata River Compact administration. L. i..::.. p.','.
