摘要

In 1986 the Bellgreen Bassmasters Club of Russellville, Alabama, requested TVA to consider changing operating guide curves for Cedar Creek and Little Bear Creek Reservoirs in northern Alabama. In response an operating alternative was selected with potential for increasing the multi-purpose recreational benefits of the reservoirs, while retaining adequate storage for flood control purposes. Beginning in 1988 and continuing through 1991, summer recreational pool levels on both Cedar Creek and Little Bear Creek Reservoirs were extended for about six weeks from October 1 to November 15. Extension of summer pool elevations is commonly perceived as enhancing recreational value of reservoirs in the Tennessee River system (TVA 1991). Additionally, winter minimum pool elevations were raised to 608 (formerly 603) and 566 (formerly 560) at Little Bear Creek and Cedar Creek Reservoirs, respectively. This report discusses the environment and economic impacts these changes have influenced.
