Water Supply Reserve Account - Grant Application Form Fonn Revised May 2007 Meeting Water Management Goals and Obiectives and Identified Water Needs This project will help address many of the SWSI Management objectives such as: 1. Sustain ably meet Municipal and Industrial Demands Reducing the spread of zebra mussels will help minimize impacts to Municipal and Industrial Demands from the spread of zebra mussels from Lake Pueblo. In other states zebra mussels have impacted municipal and industrial water supplies significantly. This project will help defer those impacts further out or if new control or eradication methods such as bio-controls become available in the next few years, then it may help ensure those impacts are never realized. 2. Sustain ably meet Agricultural Demands Again the full impact of zebra mussels to agricultural demands in Colorado are not yet known and will be projected out in the Statewide Rapid Response by the Division of Wildlife. Based on the concems expressed by other westem states, we there is the potential for impact to agricultural water supply, so this project will minimize the possibility of those or at least defer those impacts out on a longer timeline. 3. Optimize Existing and Future Water Supplies This project to minimize the spread of zebra mussels will help ensure that water supplies experience fewer impacts and less risk of reductions in water availability for critical needs. Again in other states, zebra mussel infestations have led to shutdowns and periodic outages of water supplies as facilities have required periodic maintenance to unclog and scrape off or treat zebra mussels. Many facilities have also required outages to retrofit and install new technologies to mitigation the presence of mussels. 4. Enhance Recreational Opportunities This project would allow for continued recreational opportunities at Lake Pueblo but would alter those recreational opportunities to minimize their possibility of spreading zebra mussels. 5. Provide for Environmental Enhancement This project will help protect environmental values that could be degraded by the presence of zebra mussels. Fish populations have been significantly impacted by mussel invasions in other states. Many species of endangered fish in Colorado are at risk from this invasion. Many of the endangered fish structures such as fish ladders and nets that have been constructed in the past ten years could be impacted by mussels, so minimizing the spread of zebra mussels is very important to protecting these values. 6. Promote Cost Effectiveness This project is designed based on the most cost effective best management practices from other states. The Water Activity Addresses Issues of Statewide Value This project addresses several issues of statewide value: 1. This project will help sustain agriculture and meet environmental and recreational needs a. Agriculture The potential impact of zebra mussels on agricultural water supplies is being evaluated by the Division of Wildlife as part of their Statewide Rapid Response, so at this time we don't have a complete picture of the potential impacts to agriculture. However, in Califomia they their responses are based on the assumption that their may be significant impacts to agricultural water supplies. 7
