Areas that Discharge into Designated Trout Steams

Areas that Discharge into Designated Trout Steams

Section 23 of the MPCA Construction Stormwater General Permit requires additional 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 properties include:

  • Campus (North Side) – Tischer Creek (NN (#83)) 
  • Campus (South West Corner) – Chester Creek (NN (#18)) 
  • Glensheen (South West Quarter) – Tischer Creek (NN (#83)) 
  • NRRI – Miller Creek (NN (#59))
  • Limnology (East Side) – Lester River (NN (#52)) 
  • Research and Field Studies Center – 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.

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.
