Hayden Lake is a beautiful and popular lake in our region, but it’s increasingly troubled. Kootenai Environmental Alliance has launched the multi-pronged Hayden lake Project as a concentrated effort to conserve the resource, restore water quality and protect the lake from current and future threats.

In 1998, Hayden Lake was deemed a water body with threatened water quality under Section 303(d) of the Clean Water Act, with phosphorous being identified as the significant pollutant of concern. Phosphorus pollution creates excess nutrient loading which affects cold water aquatic life by reducing the amount of dissolved oxygen available. Phosphorous sources include sediment and runoff generated by:

  • logging
  • new development in and around the watershed
  • shoreline septic systems
  • storm water
  • detergents containing phosphorous
  • ashes from campfires and forest fires
  • pet and livestock waste

Our Hayden Lake Project consists of outreach, education, and on-the-water and on-the-ground restoration projects:

Phase 1 – Expand public awareness about Hayden Lake and improve the public’s watershed IQ

Phase 2 – Permanently preserve sensitive watershed lands

Phase 3 – Deploy new technologies to remove phosphorus pollution from the water

Phase 4 – Reduce phosphorous pollution entering the lake from surrounding watershed lands[/notice]

Here is a gallery of our brand new “floating wetland” in Hayden Lake:

Year 1 = Good News!
