The Minnesota Barrier Assessment Study

Relative Risk of Invasive Carp Upstream Movement Map (PDF)

In September 2012, the DNR began a GIS-based invasive carp risk assessment project to carry out the following objectives:

The project applied GIS analysis to information gathered from several barrier databases and data from field level professionals.

A preliminary risked-based spatial map was released in November 2013 depicting where in Minnesota invasive carp may spread by their own swimming capabilities.

In addition, the project produced the following outcomes:

Future work will be done verifying and refining data, prioritizing locations for potential stream barrier enhancement, and prioritizing watershed breaches for projects to prevent passage by invasive fish species.
