The GLMRIS Report presents the results of a multi-year study regarding the range of options and technologies available to prevent aquatic nuisance species (ANS) movement between the Great Lakes and Mississippi River basins through aquatic connections. Through a structured study process, USACE identified thirteen ANS of Concern established in one basin that posed a high or medium risk of adverse impacts by transfer and establishment in the opposite basin. USACE analyzed and evaluated available controls to address these ANS, and formulated alternatives specifically for the Chicago Area Waterway System (CAWS) with the goal of preventing ANS transfer between the two basins.
The report contains eight alternatives, each with concept-level design and cost information, and evaluates the potential of these alternatives to control the transfer of a variety of ANS. The options concentrate on the Chicago Area Waterway System (CAWS) and include a wide spectrum of alternatives ranging from the continuation of current activities to the complete separation of the Great Lakes and Mississippi River basins. The GLMRIS Report also includes an analysis of potential impacts to uses and users of the CAWS, and corresponding mitigation requirements for adverse impacts to functions such as flood-risk management, natural resources, water quality, and navigation.
