The drought of 2012 was so severe that many of the coves in the lake had no water and boats in the marinas were touching the bottom of the lake.  The lack of water only exacerbated the impact of the seepage occurring in the Dam Spillway, which had been increasing over the 40 years since the inception of the dams. For the first time in 40 years, the Staff and Board commissioned major repair work on the Dam Spillway to repair the seepage. Major improvements were made to the spillway by means of a grout curtain across the entire spillway. The water seepage was reduced from 4000 GPM (gallons per minute) in 2013, down to just 750 GPM during April 2017.  Additional repairs were done in 2017 to bring it down to less than 100 GPM.
