2021 Community Meeting – Invasive Aquatic Weeds and More
Join us on April 13 for this year’s annual “weed meeting” and more! We’ve expanded the agenda to include another important concern on the lake: law enforcement. Jump to RSVP.

The Hayden Lake Watershed
More than the lake, the watershed holds all of the land, air, surface and ground water, plants and animals, mountains and lowlands, communities and farms, and people, including their stories and traditions, within its boundaries.
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 watershed is home to more than 4000 residents, many of them seasonal. But the year-round population is growing!
