Water Supply Reserve Account - Grant Application Form Form Revised May 2007 SB-179 assistance. Erosion, river channel braiding, bankfailures, and deteriorating irrigation structures are problems shared by several projects on the Conejos River irhich are being cured by WSRA support, including a project by the Romero Irrigation Company and Guadalupe Main Ditch Company. A similar project is currently being submitted for funding by the Manassa Land and Irrigation Company. The District committed 81 5, 000 to the Guadalupe-Romero project and is pledging 810, 000 to the current proposal from the Manassa Land and Irrigation Company. For these and other projects, CWCD continues to assist local communities in the implementation of channel irork on the Conejos and the San Antonio Rivers. Another CWCB-related project is the pending San Luis Falley Resource Conseri ation & Development project on the Alamosa River. Upcoming projects to CWCB iri11 inchide proposals from Alamosa Riverkeepers and Terrace Irrigation Company to upgrade Terrace Resenwir, and a riparian stabilisation project by the Colorado Rio Grande Restoration Foundation. t. The water activity helps support the State's economic vitality and competitiveness in national and international markets. Agriculture is a main driver of the economy of the San Luis valley, representing SI43,63 7, 000, or 37.9 percent of the Valley's base industry income. Tourism accounts for S43,508, 000, or 11.5 percent of base industry income. This project, by protecting the integrity ofPlatoro Reservoir, helps to support the Valley's economic vitality and competitiveness by providing for irrigation demands and by maintaining a healthy river system from high in the San Juan Mountains to the state line and beyond. 4. Please provide an overview of the water project or activity to be funded including type of activity, statement of what the activity is intended to accomplish, the need for the activity, the problems and opportunities to be addressed, expectations of the participants, why the activity is important, the service area or geographic location, and any relevant issues etc. Please include anv relevant TABOR issues that may affect the Contracting Entity. Please refer to Part 2 of Criteria and Guidance document for additional detail on information to include. Type of activity: This three-phase project repairs, replaces, and upgrades existing structures at Platoro Reservoir kvhich have nearly reached the end of their 50-year useful life. Phase I, funded by the USBR installs a bypass piping system to divert water and to maintain federally mandated minimum flows while repairs are undenvav. Phase II, paid for by the District, re-coats and paints 440 feet of penstock just above the butterfly valves in each discharge tube while at the same tone maintaining a mandatory discharge of 7cfs. Phase III, for which this proposal seeks SB-179 funding, replaces the worn out valves and operators on the dam with new ones and establishes backup systems for the future. Included Nvith this proposal are (1) photographs, engineering drawings, and a narrative for each segment of this restoration project; (2) detailed explanations of the river bypass system and piping specifications for the instrearn supply piping; and (3) a work plan to paint the penstock piping, including the CWCD personnel and employee training and safety policies for working in confined spaces, and (4) details for both of the valves' refurbishing/repair/replacement. This Project satisfies multiple uses identified by the State-,vide Water Supply Initiative (SWSI) and consumptive and non-consumptive needs of the Rio Grande Basin, as described above. Goals and Objectives: The overall goal of this structural project is to keep the Platoro Reservoir facility on the Conejos 19
