Areas that Discharge into Designated Trout Steams

Areas that Discharge into Designated Trout Steams

Section 23 of the Minnesota Pollution Control Agency (MPCA) Construction Stormwater General Permit requires additional Best Management Practices (BMPs) for discharges from the project site within one mile (aerial radius) of a special or impaired waters that then drains to those waters.  The University of Minnesota Duluth discharges storm water to several designated trout streams, as listed in MN Rules 6264.0050 Subpart 4 (2020).

These areas include:

• The north side of Campus discharges to Tischer Creek (NN (#83)) 
• The southwest side of Glensheen discharges to Tischer Creek (NN (#83)) 
• All of the Natural Resources Research Institute (NRRI) discharges to Miller Creek (NN (#59))
• The east side of Limnology discharges to Lester River (NN (#52)) 
• Research and Field Studies Center discharges to the East Branch of Amity Creek (NN (#3))
  • The RFSC is located outside the urban area of Duluth and therefore is not specifically included in the UMD Stormwater Program, however any project requiring an MPCA Construction Stormwater permit, regardless of its location, still must comply with all aspects of the permit.

Watershed maps are only available in PDF format. For additional information or potential accommodations, contact Erik Larson at 218726-6915 or [email protected].

When an MPCA Construction permit is required for any project within these watersheds the Stormwater Pollution Prevention Plan must meet or exceed the requirements of Section 23.6 of the MPCA permit # MNR100001 (Construction Stormwater General Permit).  

New or fully reconstructed projects of less than one acre that require a grading permit should include appropriate BMPs so that the project does not negatively impact the trout stream.
