在整个美国，水库被管理用于多种用途，包括水力发电，河流流量调节，洪水控制和娱乐。水电站、河流流量调节和洪水控制的水位下降常常降低水库对水上娱乐的适宜性。作为跨部门政策分析的一部分，测量了北卡罗来纳州西部四个水库在三种替代水位管理方案下户外娱乐的总经济使用价值的收益。使用价值是使用或有估价调查和专家小组数据估算的。本研究所解决的基本问题是，娱乐用户在夏季和秋季保持更长时间的更高水位上的价值是否明显大于使用这些水库的价值，因为它们在本研究时被管理。人们发现，在夏季和秋季较长时间保持高水位，在估计的娱乐效益方面会有相当大的收益。虽然不是本研究的主要目标，但这些估计为我们提供了一个机会，可以将增加的娱乐效益与田纳西河流域管理局估计的减少发电量的价值进行比较，如果湖泊设法将水库水位保持在更高的水平，更长的时间。
Throughout the United States, reservoirs are managed for multiple uses, including hydropower, stream flow regulation, flood control, and recreation. Water level drawdowns for hydropower, stream flow regulation, and flood control often reduce the suitability of reservoirs for water-based recreation. The gain in aggregate economic use value of outdoor recreation under three alternative water level management scenarios was measured for four reservoirs in western North Carolina as part of an interagency policy analysis. Use values were estimated using a contingent valuation survey and expert panel data. The basic question addressed by this study was whether the value recreational users place on higher water levels held longer into the summer and fall is significantly greater than the value of using these reservoirs as they were managed at the time of this study. Maintaining high water levels for longer periods during the summer and fall was found to result in considerable gains in estimated recreational benefits. While not a primary objective of this study, having these estimates provided us an opportunity to compare increased recreational benefits with the value the Tennessee Valley Authority estimated for the reduced production of electricity that would result if the lakes were managed to hold reservoir levels higher, longer into the year.
