Wheeler and Associates report3. The four <br />scenarios are funher discussed and defined below, <br /> <br />Scenario A is based on current deliveries and comparing the potential for storage <br />to the current storage capabilities of Lake Meredith and Lake Henry of 50, I 04 <br />AF, The combined reservoirs have a water surface area of approximately 6,949 <br />acres, The estimated annually net evaporation rate used for all alternatives is <br />approximately 52 inches, Lake Meredith annual average releases are based on the <br />last 10 years of historical average annual out flows of 41 cfs, which is <br />approximately one half of the inflows to Lake Meredith, <br /> <br />Scenario B is based on the difference between current deliveries and the <br />Colorado Canal capacity (760 cfs) and comparing the potential for storage to the <br />current storage capabilities. The existing Lake Henry and Lake Meredith <br />combined water surface is approximately 6,949 acres, Lake Meredith annual <br />average releases are based on the last 5 years of historical annual out flows of 66 <br />cfs, <br /> <br />Scenario C is based on the total Colorado Canal delivery capability of 760 cfs <br />and comparing the potential for storage to the potential storage identified in the <br />W,W, Wheeler & Associates report] The study's results indicated a proposed <br />high dam alternative with a high water surface elevation of 4260-ft, msl. with a <br />useable storage capacity of 80,823 AF. Lake Meredith annual average releases <br />are assumed to be approximately half of the Colorado Canal delivery capacity <br />including conveyance losses, <br /> <br />URS Greiner <br /> <br />- 2- <br />
