Focus Area 2 Other Aquatic Pathways

Reports are listed below for each of the potential aquatic pathways between the Great Lakes and Mississippi River basins outside of the Chicago Area Waterway System. Each report evaluates key evidence to estimate the probability of an aquatic pathway forming at the basin divide, and then of specific aquatic nuisance species (ANS) using that pathway to reach the adjacent basin.

Draft versions of these reports were released between September 2012 and March 2013 to the public for comment and inter-agency technical reviews. The updated reports below incorporate feedback received during this time.

Many of these pathway assessments include potential actions or opportunities that might prevent or reduce the probability of ANS transfer occurring between the basins. USACE continues to work with its partners on some locations to assist them in further reducing the probability of ANS transfer occurring.
