A subbasin is a unit of the national Watershed Boundary Dataset, and water crosses state lines: this one carries permits in Montana. Each permit is placed by the outfall EPA names as its representative discharge point.

This subbasin contains 5 watersheds, each with its own page of permits. The table below is a sample of the 43 current permits recorded here; the pollutant list above names every limit EPA attaches to a permit in this subbasin.
