Is it safe? Is it healthy? And, will it stay that way?
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) tracks water quality through its lake monitoring programs and supports citizen science to extend their monitoring work. 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.
