Fernan Lake is located just north of beautiful Lake Coeur d’Alene. Acre for acre, Fernan Lake is Idaho’s most popular place for recreational fishing, but high phosphorus (P) levels in this lake are now causing annual blooms of blue-green algae that diminish the use and enjoyment of this picturesque natural resource. The blooms reduce water clarity and produce unsightly thick, green mats along the shoreline and may produce toxins capable of causing illness in humans and animals and possibly death to animals. According to the Centers for Disease Control and Prevention, humans who drink or swim in water that contains high concentrations may experience gastroenteritis, skin irritation, allergic responses or liver damage.
In 2013, Idaho Department of Environmental Quality (IDEQ) crafted the prescription (called a Total Maximum Daily Load or TMDL) which identifies the sources of P that need to be addressed in Fernan Lake to meet water quality standards and return the lake to support its beneficial uses.
Kootenai Environmental Alliance began restoration of Fernan Lake Road’s eroding shoreline in Spring 2016 with support from the IDEQ Nonpoint Management Program.
The Fernan Lake watershed is comprised of all the land that eventually drains to the lake and includes all properties from the ridge tops to the valley. All households in the Fernan Lake watershed have received a short survey and we greatly appreciate your willingness to participate. Your participation is anonymous and aids Kootenai Environmental Alliance in efforts to return Fernan Lake to swimmable, fishable water.
