The mining district in the South Fork Coeur d’Alene River valley was among the Nation’s largest producers of silver, lead, zinc, and other metals from the 1880s to the 1980s. These activities have produced large quantities of waste material that contain environmentally hazardous contaminants such as cadmium, lead, and zinc. Much of this material has been discharged directly to or washed into the South Fork Coeur d’Alene River and its tributaries, and continues to make its way to Coeur d’Alene Lake and beyond.
We conducted two large-scale studies of the lake (1991-92 and 2004-06) to understand the complex interaction of physical, chemical, and biological processes in the lake and the resulting water-quality conditions. We've assessed temporal and spatial differences and identified potential changes and trends in lake water quality over time. The insights gained from these studies can be used by decision-makers to manage Coeur d’Alene Lake water quality and contaminants in the basin.

Coeur d'Alene Lake, Idaho: Insights gained From limnological studies of 1991-92 and 2004-06
More than 100 years of mining and processing of metal-rich ores in northern Idaho’s Coeur d’Alene River basin have resulted in widespread metal contamination of the basin’s soil, sediment, water, and biota, including Coeur d’Alene Lake. Previous studies reported that about 85 percent of the bottom of Coeur d’Alene Lake is substantially enriched in antimony, arsenic, cadmium, copper, lead, mercury,

Free zinc ion and dissolved orthophosphate effects on phytoplankton from Coeur d'Alene Lake, Idaho
Coeur d'Alene Lake in northern Idaho is fed by two major rivers: the Coeur d'Alene River from the east and the St. Joe River from the south, with the Spokane River as its outlet to the north. This phosphorus-limited lake has been subjected to decades of mining (primarily for zinc and silver) and other anthropogenic inputs. A 32 full-factorial experimental design was used to examine the interactiv

Importance of Sediment-Water Interactions in Coeur d'Alene Lake, Idaho, USA: Management Implications
A field study at Coeur d'Alene Lake, Idaho, USA, was conducted between October 1998 and August 2001 to examine the potential importance of sediment-water interactions on contaminant transport and to provide the first direct measurements of the benthic flux of dissolved solutes of environmental concern in this lake. Because of potential ecological effects, dissolved zinc and orthophosphate were the

Nutrient and trace-element enrichment of Coeur d'Alene Lake, Idaho
The limnological characteristics and geochemistry of lakebed sediments in Coeur d'Alene Lake were assessed during 1991-92 because of the possible interaction of nutrient enrichment with the highly enriched trace-element concentrations stored in the lakebed.
