Morrison = 136.25 (.164 ) = 22.34 a.f. 272.5 When each entity's storage account and evaporation loss account are full, inflows could not be stored and will be released to the river. Example Operations Study To illustrate the operations study procedures described herein, the Colorado Water Conservation Board staff has taken the estimated storable inflows and releases to the river from a first draft of a Bear Creek Reservoir Operations Study prepared by WWE in 1979 and has conducted an operations study for W.Y. 1954. This study is attached as Appendix A and will serve as a guide as to how the consultant is to conduct the current study. In this example study, the estimated storable inflows and releases to the river are based on incomplete data. The example study should, therefore, be viewed as a sample calculation, not as a valid study. It does, however, point out the need for each entity to carefully evaluate how much water it needs to store to meet its release requirements and evaporation loss obligations. Study Products The consultant shall prepare 25 copies of a draft final report. This report will show the monthly fluctuations in the water surface elevation of Bear Creek Reservoir under Scenarios A, B & C during the sele9ted hydrologic cycles. In addition the study will show whether each entity has allocated sufficient water rights for storage in Bear Creek Reservoir to meet its augmentation requirements and its evaporation losses. After review and comments are made by the parties involved, 25 copies of a final report shall be prepared. -9-
