Water Quality Study of Metals in the Beaverhead Watershed Available for Comment

Helena—The Montana Department of Environmental Quality (DEQ) is seeking comments,  and holding a remote public meeting, on a draft plan that determines the total maximum daily load (TMDLs) for metals in nine impaired stream segments within the Beaverhead watershed in Beaverhead and Madison counties.

The draft “Beaverhead Metals TMDLs” plan describes water quality problems related to metals. Nine stream segments in the Beaverhead watershed are not meeting Montana’s water quality standards and the document provides TMDLs to help address these problems. Total maximum daily load is a plan that identifies the maximum amount of pollutant water can receive while still meeting water quality standards. The document also outlines a strategy for reducing pollutant concentrations in order to meet Montana’s water quality standards.

DEQ is hosting a remote public meeting on Aug. 4, 2020 for the public to learn more about the process and findings. The meeting is accessible both online and by telephone and will include a small presentation and provide opportunity for questions.
