USACE Releases Eagle Marsh ANS Controls Report

Nov 16: The Army Corps of Engineers (USACE) released the Eagle Marsh Aquatic Nuisance Species (ANS) Controls Report for public review and comment. Eagle Marsh, which is located in Fort Wayne, Indiana, has been identified as a potential pathway where ANS may spread between the Mississippi River and Great Lakes basins. This potential pathway was identified in the report titled Great Lakes and Mississippi River Interbasin Study Other Pathways Preliminary Risk Characterization released in 2010. A 60-day public comment period begins on November 16, 2012 and ends January 14, 2013.

    The purpose of the Eagle Marsh ANS Controls Report is to identify a permanent means to prevent the spread of Asian carp and other aquatic nuisance species across Eagle Marsh as efficiently and effectively as possible. In the report, nine structural alternatives are compared and at least three were determined to have a "high" likelihood of preventing interbasin spread of ANS across Eagle Marsh. A range of non-structural alternatives are also described that could complement any structural solution.

    USACE actively coordinated with the Indiana DNR, U.S. Geological Survey, Natural Resources Conservation Service, U.S. Fish and Wildlife Service, U.S. EPA, Council on Environmental Quality, Little River Wetlands Project, Maumee River Basin Commission, Allen County Soil and Water Conservation District and Allen County Surveyor's Office throughout development of the report. Their contributions significantly improved the quality of the report and reflect significant interest and capabilities that may be applied toward long-term prevention of the spread of ANS across Eagle Marsh.
