Summary

IMPORTANT NOTE: Data and supporting information from samples collected during 2015-16 can be can be accessed from this link. The U.S. Geological Survey is studying Lake Koocanusa, a border reservoir between British Columbia in Canada and Montana, in collaboration with the Montana Department of Environmental Quality and the U.S. Environmental Protection Agency (Region 8). This work is part of a multi-agency project to apply an ecosystem-scale selenium modeling methodology (Presser and Luoma, 2010) to the lake to support development of site-specific selenium guidelines for the protection of aquatic life. A conceptual model framework was published in 2017 (Jenni, Naftz, and Presser, 2017) to serve as a coherent and consistent structure [...]

Purpose

This dataset was collected to help understand the variability in dissolved and suspended particulate material selenium concentrations 1) within the hydrodynamics and limnology of the lake; and 2) as components of modeling the ecosystems of Lake Koocanusa. The dataset also contributes to the overall understanding of such factors as the upstream loading of selenium from coal mining in the Elk River Valley in southeastern British Columbia and the ecosystem effects of the management of Libby Dam in northwestern Montana.
