On June 9, the Association hosted an open meeting to update all on the status of the North Arm.

The North Arm of Hayden Lake is undoubtedly very different than the rest of the lake. It extends from Sportsman’s Park on the north end, 1.5 miles south to Henry’s Point. Geoff Harvey, President of the Hayden Lake Watershed Association, is fond of saying that Hayden Lake is really two lakes – one is the North Arm, the other is the Main Body.

To start the meeting, Geoff shared a synopsis of the history of the North Arm. He explained why it exists, and how it differs from the Main Body. Also from the Association’s Executive Board, Gil Rossner updated residents on weed growth and treatment. Invasive and noxious weeds are an ongoing concern for homeowners and recreators; they grow dense and disruptive and are making their way down the North Arm into the Main Body of the lake.  Geoff also reviewed the nutrient status of the area’s shallow waters and how they support weed growth in the spring and blue-green algae growth in the summer. The team wrapped up their presentation with a discussion of management options, i.e., herbicides or no herbicides, dredging, and Alum treatment.
