Sorry I am new to this forum so hope I’m doing this right. We have about a 300 acre lake that interesting has a saline concentration of about 4 ppm in Nebraska. It was dredged approximately 10 years ago and had a large fish kill at the time. Since this dredging it has had a breakout infestation of midges. They have tried to add back fish to control the larvae but have had trouble maintaining a fish population due to the saline content as well as a large population of pelican’s that frequent lake. Does anyone have any suggestions as to how to control this midge population. Thanks.
