Barren River Dam is located in Allen County in south central Kentucky. The reservoir has the largest drainage area in the Louisville District (940 square miles) and relatively low maximum seasonal release rates compared to other projects within the district (crop season - 3,200 cfs and non-crop season – 4,000 cfs). When the project was initially impounded the normal maximum release rate was 6,000 cfs. Over time, this maximum release rate has been reduced to 4,000 cfs, a 33% loss in release capacity. A maximum release of 4,000 cfs has been use for many years with uncertainty about the impacts of releasing above 4,000 cfs and up to 6,000 cfs. Additionally, the schedule of regulation gives authorization to release up to 6,000 cfs and states “when conditions dictate the need for depletion of reservoir storage at a faster rate, it may be possible to discharge up to the maximum design rate of 6,000 cfs. This decision would involve consideration of time of year, current and forecasted weather conditions, and percentage of flood control storage utilized. The decision would be dependent on the notification of downstream interests.” Project personnel have identified potentially impacted areas during higher releases, and the CWMS model could help address the benefits and downstream impacts of going to a higher maximum release rate.
