The reservoir is a Corps of Engineers' <br />flood control facility located on Bear Creek near Lakewood and <br />Morrison. The then Executive Director of the Department gave <br />tentative approval to these requests. which totaled 305 a.f.. <br />on the condition that the State would not grant final approval <br />until a complete operating plan was submitted by each entity <br />for review by the Department and until approval was secured <br />from the Corps of Engineers. <br /> <br />Recently, additional storage space has been requested by <br />Evergreen and the Town of Morrison. The Mt. Carbon <br />Metropolitan District and the City of Lakewood have also <br />requested storage space in Bear Creek Reservoir for the storage <br />of municipal and augmentation water supplies. These requests <br />for storage space now total 2225 a.f. <br /> <br />To address concerns with respect to the impact of <br />fluctuating reservoir levels on present and future recreational <br />facilities and uses within the reservoir area. the involved <br />parties have agreed to conduct an operations study to determine <br />how reservoir levels will fluctuate under various hydrologic <br />conditions and water development/use scenarios. This scope of <br />study sets forth the analyses which will be required of the <br />engineering consulting firm retained to perform the operations <br />study. Each major element of the study is set forth below. <br /> <br />Hydroloqic System <br /> <br />The following three hydrologic cycles shall be modeled: <br /> <br />Dry cycle = <br /> <br />Average cycle = <br /> <br />Wet cycle = <br /> <br />[What are the recommendations of the engineers for the <br />various entities on which years should be modeled? At minimum <br />each cycle should include at least 3 years. with the critical <br />year(s) to be in the middle of the cycle.] <br /> <br />2504E <br /> <br />I <br />
