Final Roseau River Watershed Total Maximum Daily Load Study

The Clean Water Act, Section 303(d) requires that total maximum daily loads (TMDLs) be established for
surface waters that do not meet water quality standards (Minn. R. 7050.022) to support their
designated uses. A TMDL determines the amount of a pollutant a receiving waterbody can allow, while
meeting water quality standards. Through the TMDL, pollutant loads are allocated to nonpoint and point
sources within the upstream watershed discharging to impaired waterbodies. This TMDL assessment
addresses one total suspended solids (TSS) and one bacteria (as Escherichia coli [E. coli]) impairment in
the Roseau River Watershed (RRW). Both impairments occur on Hay Creek, a tributary to the Roseau
