The Hayden Lake Watershed
More than just the lake, the Hayden Lake watershed includes the land, water, wildlife, and people who depend on it. The Hayden Lake Watershed Improvement District works with the community to protect water quality and care for this important North Idaho resource.
Drinking Water Grant Project
Safe, clean drinking water is at the heart of life around Hayden Lake. Our Drinking Water Grant Program helps local residents and property owners protect water quality, maintain healthy wells, and support the long-term care of the watershed we all share.
Water Quality
The quality of Hayden Lake’s water remains high through decades of the conscious efforts of citizens and government agencies. The Hayden Lake Watershed Improvement District (HLWID) monitors the nutrients in the North Arm. They also track the phosphorus entering the lake via runoff on the south shore. Their aim is first to contribute objective data to planning processes for lake protection. Second, they work to understand the complex mechanisms that govern the changes to the lake over time. Additionally, the HLWID observes what’s happening around the lake to ensure that visitors and residents adhere to best practices. These help the water that we all enjoy remain clean and clear now and in the future.
Recreation
The quantity and quality of opportunities for recreation on Hayden Lake are one of its greatest draws. Generations of lake visitors and residents have enjoyed the clear, cool waters and rocky shoreline. Fishing, swimming, boating, sightseeing, and picnicking number among the activities for all to enjoy.
Living on Hayden Lake
The Hayden Lake watershed is home to more than 4,000 residents, many seasonal, with the year-round population steadily growing. Need help with your property?
