DEQ seeks comment on proposed plans to lower E. coli bacteria in Brownlee Flats tributaries
Accepting Comments from October 14, 2020 to November 13, 2020
BOISE — The Idaho Department of Environmental Quality (DEQ) seeks public comment on proposed plans to address elevated Escherichia coli (E. coli) bacteria in several tributaries that drain into the Brownlee Reservoir below the Weiser Flats area.
These tributaries Jenkins Creek, Scott Creek, Warm Springs Creek, Hog Creek, Rock Creek, Little Rock and Henley Creeks.
Recent analyses reveal that E. coli levels exceed state water quality standards in these streams, which can pose health risks to people recreating in water.
Under the Clean Water Act, states are required to develop total maximum daily loads (TMDLs) when state water quality standards are not achieved. To comply with these requirements, DEQ prepared the draft Brownlee Reservoir Subbasin - Weiser Flats Total Maximum Daily Load - Bacteria, which defines maximum E. coli inputs from all sources that can occur while still meeting state water quality standards.
