PATENT PENDING <br />SYSTEM AND METHOD FOR SELECTIVELY DIVERTING WATER AND <br />PROVIDING PEAK HYDROELECTRIC POWER <br />x <br />CCP’s newly developed Colorado River Compact entitlements can conserve and <br />optimize use of damaging spring flood flows for Upper Gunnison Basin - of - origin needs. <br />These local needs inclu de flood control, and optimized river flows for droughts, growth, <br />irrigation, and recreation; <br />x <br />CCP will provide managed optimal flows for Black Canyon of the Gunnison National <br />Park and the Colorado River Endangered Fish Recovery Program. Lake Union Park <br />ca n also become a world destination Lake Trout fishery; <br />x <br />Water productivity multipliers from CCP can reverse regional water shortages from <br />urban growth, which are escalating loss of irrigated Western farms and green valleys; <br />x <br />CCP’s integrated regional capabi lities obviate current local proposals to develop non - <br />integrated Colorado conditional use and reuse water rights, that would excessively <br />deplete West and East Slope rivers to less than 50% of historic native flows; <br />x <br />During long wet cycles, CCP’s pumped - sto rage infrastructure can be used to recharge <br />declining Western ground water reserves, including the vital Ogallala, Denver, and San <br />Luis aquifers; <br />x <br />CCP’s high - altitude pumped - storage concept can reduce regional evaporation losses. <br />For example, projected ann ual evaporation from the largely frozen 7.8 square mile <br />surface of Lake Union Park is about 1½ feet vs. up to 7 feet from hot desert storage <br />sites. The West is losing a large portion of its finite renewable water supplies to <br />evaporation from low - altitude r eservoirs; <br />x <br />CCP’s high storage and responsive water regulation capabilities can be used by <br />Colorado and down river states to assure equitable development and maximum <br />productivity from their respective interstate compact entitlements. Snowmelt and rain <br />from Colorado’s high mountain te rrain generates a large potion of all renewable waters <br />that flow in the Southwestern Region’s five major river systems. All down - river states <br />can gain from CCP’s flexible headwater storage in Colorado; <br />x <br />Water conservation, produ ctivity, and regulating advancements from CCP can offset <br />potential adverse impacts from global warming, while reducing long - term renewable <br />energy and water costs for Western consumers. <br />FLOOD AND PUBLIC SAFETY BENEFITS <br />Recent Department of Interior and B ureau of Reclamation dam safety studies [3, 4, 5] <br />predict Taylor Park, Blue Mesa, and Pueblo Dams could suddenly fail with floods above <br />55% of the projected Probable Maximum Flood (PMF). In addition to the high hydrologic or <br />flood failure risk (inadequate spillway capacity and possible overtopping of the structure), <br />Taylor Park Dam may also fail during a moderate seismic event that could liquefy materials <br />in the embankment or foundation. Considering the hazards at all three dam locations, a n <br />estimated 16,00 0 lives are currently at risk.
