Description Bioassays and metals analyses were conducted on sediment samples from 14 sites on the Spokane River. The samples were obtained from a USGS study on downstream dispersion of trace elements from Lake Coeur d’Alene. Results from the bioassays were unusable due to errors made by the contract laboratory. Metals results were consistent with historical data in showing elevated to extremely high concentrations of zinc, lead, and cadmium in sediment samples from most parts of the river.
