Mining and Watersheds (2019)

During late October 2019, the University of Montana’s Flathead Lake Biological Station hosted a workshop titled, Advancing scientific knowledge of mining impacts on salmonid-bearing watersheds.

Thirty-nine science and policy experts from academic institutions, state/provincial and federal agencies, indigenous governments, and non-governmental organizations gathered to participate in the collaborative workshop. Those in attendance included representatives from Alaska, Idaho, Montana, Washington, British Columbia, and Ontario.
