Flat Creek has been designated as an ‘impaired stream’ by the US Environmental Protection Agency and the Wyoming Department of Environmental Quality since 1996. In response to that listing, which identifies stormwater runoff and habitat alteration as root problems, the Flat Creek Watershed Management Plan was drafted in 2006. This stakeholder- and community-driven effort established a baseline understanding of the issues facing Flat Creek and identified a series of actionable projects to address those challenges. Since 2006, twenty of the twenty-two objectives outlined in the Watershed Plan were completed, making the original plan outdated. With a grant from the Wyoming Department of Environmental Quality, Teton Conservation District led an effort to bring the Flat Creek Watershed Management Plan up to date. The revised plan includes new project ideas, a list of accomplishments, summarizes existing data, and sets discrete goals for water quality and stream health in Flat Creek.
