Category: Water Quality

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.

Don’t Forget Your Site Disturbance Permit

It’s hard, as individual property owners, to embrace the impact that a single decision – like proceeding with a project before permit approval – has on our surroundings.  The effect isn’t immediate, and it isn’t a direct reaction to our choices.  It takes time for the chain reaction to play out.  Ask the 5, 10, 15, and 20-year residents whether Hayden Lake’s water is as clear, or the bottom as sandy, or the shoreline as raw and unfettered as it used to be.
