本报告的目的是确定根据现有蓄水权引水的可行性 Chatfield水库中因洪水控制到保护的蓄水重新分配而产生的空间 目的。这项工作是美国陆军工程兵团（Corps）调查的一部分，以确定 将查特菲尔德水库防洪库容重新分配用于供水目的的可行性。查特菲尔德 水库位于科罗拉多州利特尔顿附近的南普拉特河上，是为洪水而修建的 控制和娱乐目的。 此次调查的主要任务包括: 开发水库容量的目标量，以便根据洪水进行重新分配 控制空间，增加保护存储空间； 确定重新分配的查特菲尔德水库蓄水的潜在用户； 确定潜在用户可在重新分配的区域储存的特定水权 空间 确定潜在用户将如何实际使用重新分配的查特菲尔德水库 储存并为其潜在用途制定具体的目标释放时间表； 获取可用的建模数据； 为重新分配的水库的目标数量开发具有代表性的存储使用模式 存储和 确定根据现有供水权改道供水的可行性 储存在查特菲尔德水库。 调查的潜在重新分配存储池包括2900英亩英尺（5434英尺）和4500英亩- 英尺（5435英尺海拔高度）、7700英亩英尺（5437英尺海拔高度）和20600英亩英尺（5444英尺海拔高度）。这些价值观 我们在- 由美国陆军工程兵团根据之前的水库路由研究选择。在这个过程中 经过调查，在确定是否需要更大的重新分配存储池方面花费了大量精力 应该进行调查。在进行额外计算后，与研究咨询小组和 与奥马哈区、美国陆军工程兵团和科罗拉多州水资源保护局的会议 委员会决定使用美国陆军工程兵团为本次调查指定的四个储水池。 4500英亩储水池的模拟分析结果，出于实际目的， 本文报告的结果与2900、7700和20600英亩英尺水池的结果没有区别。 包括桌子。

The purpose of this report is to determine the feasibility of diverting water under existing rights to storage space in Chatfield Reservoir resulting from the reallocation of storage from flood control to conservation purposes. This work is part of a U.S. Army Corps of Engineers (Corps) investigation to determine the feasibility of reallocating flood control storage in Chatfield Reservoir to water supply purposes. Chatfield Reservoir is located on the South Platte River near Littleton, Colorado and was constructed for flood control and recreational purposes. Major tasks for this investigation included: developing target amounts of reservoir capacity to be analyzed for reallocation from flood control space to additional conservation storage space; identifying potential users of the reallocated Chatfield Reservoir storage; identifying specific water rights available to the potential users for storage in the reallocated space; determining how the potential users would actually use the reallocated Chatfield Reservoir storage and develop specific target release schedules for their potential uses; acquiring available modeling data; developing representative storage use patterns for the target amounts of reallocated reservoir storage; and, determining feasibility of diverting water under existing rights to reallocated water supply storage in Chatfield Reservoir. The potential reallocated storage pools investigated included 2,900 acre-feet (5,434 ft. MSL), 4,500 acre- feet (5,435 ft. MSL), 7,700 acre-feet (5,437 ft. MSL), and 20,600 (5,444 ft. MSL) acre-feet. These values were pre-selected by the Corps based on previous reservoir routing studies. In the course of this investigation, considerable effort was expended in determining whether a larger reallocated storage pool should be investigated. After additional calculations, meetings with the Study Advisory Group and meetings with the Omaha District, U.S. Army Corps of Engineers, and the Colorado Water Conservation Board, it was determined to use the four storage pools specified by the Corps for this investigation. The results from simulation analysis of the 4,500 acre storage pool were, for practical purposes, indistinguishable from the results obtained for the 2,900, 7,700 and 20,600 acre-feet pools are reported in this paper.
