<br />and the resulting 57,100 acre-feet average annual depletion limitation to the San Juan River, <br />the first phase has been separated into two distinct stages (A and B), as shown in Tables 1 and <br />2. <br /> <br />Phase I - Water Supply, Facilities, and Operation (proposed Plan) <br /> <br />Detailed descriptions of the facilities are included after the general description of the proposed <br />Project. <br /> <br />Phase I, Stage A <br /> <br />Phase I, Stage A - Water Supply <br /> <br />Reclamation would develop an initial average annual water supply for Project uses of <br />80, 100 acre-feet, consistent with the requirements of the existing Biological Opinion. <br /> <br />. <br /> <br />Phase I, Stage A - Facilities <br /> <br />Facilities constructed for Phase I, Stage A would include: Durango Pumping Plant, Ridges <br />Basin Inlet Conduit, Ridges Basin Dam and Reservoir, a small Ridges Basin Pumping Plant, <br />and Durango, Shenandoah, and La Plata Rural M&I Pipelines (table 1). Recreation and fish <br />and wildlife facilities would also be developed, <br /> <br />In Phase I, Stage A, Durango Pumping Plant and its appurtenant structures would be designed <br />and constructed with capacity to accommodate future water deliveries (phase I, Stage B and <br />Phase II). The capacity of the plant in Phase I, Stage A would be 70 cfs at full reservoir <br />(maximum static head). <br /> <br />Durango M&I Pipeline would be constructed to deliver Project water from Durango Pumping <br />Plant to the city of Durango's existing storage reservoir, Durango Terminal Reservoir. The <br />pipeline would be approximately 3.2 miles long and would have a capacity of 11 cfs. <br /> <br /> <br />Ridges Basin Dam would be constructed in two stages: (1) foundation preparation and (2) <br />embankment placement. During the first phase, the footprint of the dam would be excavated, <br />and the necessary grouting of the abutments and foundation would occur. <br /> <br />,:.;, <br /> <br />1.. <br /> <br />Based on the Service's post research study Biological Opinion, the size of the dam and <br />reservoir would be determined, and the dam and pumping plants could be sized accordingly. 11 <br /> <br />In lieu of Long Hollow Tunnel and Dry Side Canal, which would not be constructed if future <br />ESA consultations do not allow additional depletions, the La Plata Rural M&I Pipeline would <br />be constructed to deliver municipal water from Ridges Basin Reservoir to the La Plata rural <br />area. <br /> <br />II Final sizing of the festures would be determined following consideration of the post research study Biological Opinion, <br /> <br />20 <br />
