Some info from the game and fish biologist about the fish kill this past weekend.
Recent Gelatt Lake fish kill event: On Friday July 9th anglers at Gelatt Lake were catching fish. But by the morning of July 10th, hundreds of trout were lost due to low oxygen conditions. In addition, thousands of dead Fathead Minnows were observed. Oxygen most likely fell to lethal levels during the night due to plant respiration. While a good proportion of fish died from a lack of oxygen, it was not a total fish kill. There have been reports of fish still being caught since the event. Aerators were in operation and might have provided a zone of better oxygenated water for some fish to survive.
