(Area) Minor fish kill events have been reported at both Littlefield Lake and the Greenfield City Reservoir.
Weather conditions are largely to blame. Bryan Hayes, DNR Fisheries Biologist, explains water temperatures have been between 82-85 degrees at the surface. This concentrates nutrients. “Just sets us up to grow a lot of algae and turn these lakes greener than normal…With algae or water that’s kind of green, you get wide fluctuations in dissolved oxygen.”
Greenfield City Reservoir had an algae bloom late last week resulting in the loss of around 100 fish. Hayes says there are plenty of fish left that didn’t succumb to these conditions. “Probably what happened was an oxygen sag in a portion of the lake that caught these fish. The same thing happened at Littlefield. Early in the week I got a call from the County Conservation Board Director that they were seeing some fish dying. There I don’t think you could even count 100, you’d have probably got to about 50.”
