New study of Lake Coeur d’Alene shows water quality gradually improving

Idaho News
Spokane Public Radio The new study says heavy metals, phosphorus levels are steadily decreasing. Doug Nadvornick/Spokane Public Radio A National Academy of Sciences draft report concludes the quality of the water in Lake Coeur d’Alene has improved over the years. The report was shared this week at a symposium in Coeur d’Alene. Dan McCracken from the Idaho Department of Environmental Quality says the study found that the main sources of pollution — heavy metals and phosphorus — are entering the lake at lower levels than in the past. “Although we are still a long ways away from where we want to be, we’re starting to see some water quality improvements, just in the last five-to-10 years. Metals loading, coming from the upper Coeur d’Alene River, has consistently been improving since…

Idaho Seeking $2M Worth Of Project Ideas To Reduce Phosphorous In Lake Coeur d’Alene

Idaho News
By Samantha Wohlfeil, Inlander Idaho's Department of Environmental Quality will soon be awarding $2 million to projects that will reduce phosphorous on Coeur d'Alene Lake. The funding from the state is part of Gov. Brad Little's "Building Idaho's Future" plan. The projects are intended to prevent the lake from reaching a dangerous tipping point where heavy metal contamination that has mostly remained in sediments could become suspended in the water column due to a shift in the water chemistry. Like much of North Idaho, the lake faces issues with contamination deposited during decades of silver and lead mining in the region. To be eligible, projects must include on-the-ground reductions in phosphorous, be located in Idaho within the watersheds that drain into Coeur d'Alene Lake, and have community support. Projects on…
