Two separate ‘fish kills’ affecting species in Lake of the Ozarks
Various factors are currently causing two separate fish kills in Lake of the Ozarks, according to a Missouri Department of Conservation resource scientist.

Rebecca O’Hearn, a water pollution biologist who coordinates the fish kill and water population program for the department, said several species are being affected by a naturally occurring virus or disease as well as turbine causing deaths from swimming through the Truman Dam.

The first fish kill, estimated to be from the 38-mile marker to the 55-mile marker, is affecting channel and blue cat fish, walleye, crappie, and drum. A pathologist with MDC is scheduled to collect samples in the Lake of the Ozarks on Wednesday, June 21, 2017 to determine the specific bacteria, virus, fungus or disease causing high mortality rates.

The MDC is more concerned with a second fish kill affecting large, mature paddlefish near Warsaw. The first report the department received was on May 5, 2017 and began as soon as Truman Dam started releasing a high flow out of their spill gates.

European Frog-Bit: Be on the Lookout for This Aggressive Invasive Plant - European frog-bit is listed on Michigan’s Aquatic Invasive Plant Watch List, which identifies species that present an immediate and significant threat to Michigan’s natural resources. European frog-bit produces dense, floating mats that cover large areas of shoreline. These mats can hinder recreation, reduce waterfowl and fish habitat, and reduce light conditions for beneficial native aquatic plants.
