Managing for clean water, and a healthy, productive lake is something that all stakeholders can agree upon.
Linked below you will find aquatic vegetation and water quality surveys of Loon Lake from previous seasons.
Current chemical application practices on Loon Lake have raised some concerns about what has been introduced to the lake’s water and sediment, and the documented adverse environmental impacts they may pose. Of particular concern is the consistent application of Copper-based algaecide in Loon Lake. Copper Sulfate/Chelated Copper has been documented as being highly toxic to aquatic invertebrates and fish eggs. It does not biodegrade, meaning that the product remains in a lake’s sediment indefinitely, and can be found in core samples.
