Low oxygen levels cause mass fish kill off | East Fork Lake State Park | Cincinnati, Ohio

Taken at East Fork Lake Beach (State Park), October 2015. Low oxygen levels cause fish kill at East Fork Lake, ODNR says (http://www.wlwt.com/article/low-oxyge...) BETHEL, Ohio — Hundreds of dead fish are washing up on the shores of East Fork Lake in a fish kill so extensive it’s surprising even long-time fishermen. “I didn’t expect to see this,” said Barry Jackson, who came to the lake with his fishing rod, “I’ve been fishing up here since 1992 and I haven’t seen anything quite like this before.” Watch this story Officials with The Ohio Department of Natural Resources said they have been monitoring the problem since last week. “We are seeing a fish kill due to a phenomenon known as turnover,” said ODNR Fish Management Supervisor Debbie Walters. Walters said “turnover” is a naturally occurring phenomenon and can become an issue in the spring and fall. It happens when the temperature of the warmer water on the top of a lake begins to match the colder deeper waters and the two mix. The deep water has little to no oxygen. When low-oxygen water mixes with the oxygen-rich water where the fish live, those upper-level oxygen levels drop causing some fish stress and die.
