<br />DOLORES TUNNEL <br /> <br />The Dolores Tunnel carries water through the Dolores-San Juan Divide about 2 <br />miles west of the town of Dolores. It replaces the old MVIC Tunnel which has <br />been abandoned and plugged. The maxirut~ capacity of the new tunnel is 520 <br />cubic feet per second. <br /> <br />DOLORES CANAL <br /> <br />~ <br /> <br />The Dolores Canal begins at the outlet of the Dolores Tunnel and extends 0.6 <br />miles to the south and east, supplying irrigation water to an existing canal <br />system and M&I water to the City of Cortez and Montezuma Water Company. The <br />canal will also carry water to the Towaoc Canal Powerplant. The initial <br />capacity is 520 cubic feet per second, and the terminal capacity is 475 cubic <br />feet per second. <br /> <br />,.: <br /> <br />TOWAOC CANAL POWERPLANT <br /> <br />i; <br />r- <br /> <br />The Towaoc Canal Powerplant will have a capacity of 11.5 megawatts and will <br />produce an average-of 30,318,000 kilowatt-hours annually. A 78-inch diameter <br />buried pipe penstock will head at a structure on the Dolores Canal and extend <br />2.2 miles southwest to the powerplant. The powerplant will discharge water <br />into the beginning of the Towaoc Canal. <br /> <br />TOWAOC CANAL <br /> <br />The Towaoc Canal will begin at the Towaoc Canal Powerplant and extend south <br />and west 39.5 miles to the full-service lands in the Towaoc area. For the <br />first two-thirds of its length the canal will approximately follow the routes <br />of two existing MVIC canals, the Lower Hermana Lateral and the Highline Ditch, <br />which the Towaoc Canal will replace. The initial capacity will be 420 cubic <br />feet per second and the terminal capacity will be 135 cubic feet per second. <br />The canal will have approximately 160 turnouts to Montezuma Valley farmlands, <br />four turnouts to the Rocky Ford Laterals, and three turnouts to the Towaoc <br />Laterals. <br /> <br />ROCKY FORD LATERALS <br /> <br />Four pipe lateral systems will be constructed to deliver irrigation water <br />under gravity pressure from the Towaoc Canal to farmland currently served by <br />MVIC's Rocky Ford Ditch. The Rocky Ford Ditch has been identified as a major <br />source of salinity in the Montezuma Valley area and will be largely abandoned <br />and obliterated when the Rocky Ford Laterals are completed. <br /> <br />MVIC CANAL LINING <br /> <br />Portions of the Lone Pine and Upper Hermana Canals which have been identified <br />as significant sources of salinity problems will be reconstructed to minimize <br />seepage and to correct structural deficiencies. Approximately 7.5 miles of <br />canal will be reconstructed and lined with compacted clay. <br /> <br />3 <br />
