I I I I I I I I I I I I I I I I I I I A description of each of these alternatives follows: Alternative G - The Gurlev and Cone Collection and Regulatorv Storage Svstems with ImDrovements - This alternative would benefit the existing Farmers Water Development Company and the Lone Cone Ditch and Reservoir Company with a total service area of about 12,500 acres. Increased water supply would be provided by increasing the efficiency of diverting peak snowmelt runoff. Construction would include diversion structure modifications along the Gurley (Intake) Ditch and increased capacity of East Cone Intake Ditch. A principal feature is the enlargement of Cone Reservoir from the present 1,800 acre-feet to a capacity of 5,800 acre-feet. Management of the regulatory storage of both Gurley and Cone Reservoirs would be improved with a connection from Gurley Ditch to Cone Reservoir. This alternative would provide supplemental water and extend the irrigation water delivery season in the Norwood-Redvale service area. The project configuration for Alternative G is shown on Figure V-2. Alternative L - The Lilvlands Distribution and Regulatorv Storage Svstem Augmented bv Additional Collection and Storage Facilities - This alternative would provide supplemental water and extend the irrigation delivery season for the service areas of 360 acres in East Lilylands and 1,180 acres in Dry Creek Basin. A principal feature is the enlargement of Lilylands Reservoir from 700 acre, feet to a capacity of 6,500 acre, feet. The reservoir intake canal would be reconstructed at a higher elevation to accommodate the higher reservoir level. A new diversion structure would be erected on West Naturita Creek. Construction of an intake canal extension would be completed along an old ditch alignment from West Naturita Creek to Brewster Creek to obtain additional supply. The main channel of the distribution canal would be rehabilitated to the bifurcation to the north and south laterals. The project configuration for Alternative L is shown on Figure V-3. Alternative H - The Combined and Interconnected Gurlev. Cone and Lilvlands Svstem - This alternative would supply supplemental water to the Norwood- Redvale, the East Lilylands and the Dry Creek Basin service areas. It would provide the operational flexibility of permitting the transfer of excess Gurley-Cone water to the Lilylands area. All of the features of both Alternatives G and L, described above, are included in Alternative H. In addition, the Lilylands Intake Canal would be further extended from Brewster Creek to connect with the enlarged Cone Reservoir. The West Branch of the Cone Intake Ditch would be abandoned and the flows would be intercepted by the extended Lilylands Intake Canal. The project configuration for Alternative H is shown on Figure V-4. v-s
