Published Aug. 14, 2020

The master plan encompasses the Upper Mississippi River from the Twin Cities to Lock and Dam 10 in Guttenberg, Iowa.

The current plan is reflective of changes in policy related to master plan content, format and land classification.

Additional updates occurred in 1983 and 1988, as well as a 2011 land use allocation plan.

In accordance with the National Environmental Policy Act, a final determination master plan’s draft environmental assessment will be made following a 30-day public review period. A copy of the draft EA can be viewed and downloaded from the St. Paul District website at:
