Inventory of Available Controls for Aquatic Nuisance Species of Concern: Chicago Area Waterway System

摘要

The U.S. Army Corps of Engineers (USACE), in conducting the Great Lakes and Mississippi River Interbasin Study (GLMRIS), will explore options and technologies that could be applied to prevent aquatic nuisance species (ANS) transfer through aquatic pathways within the United States between the Great Lakes (GL) and Mississippi River (MR) basins. The USACE authorization, Section 3061(d) of the Water Resource and Development Act of 2007, for GLMRIS states as follows: . . . (USACE) in consultation with appropriate Federal, State, local, and nongovernmental entities, shall conduct, at Federal expense, a feasibility study of the range of options and technologies available to prevent the spread of aquatic nuisance species between the Great Lakes and Mississippi River Basins through the Chicago Sanitary and Ship Canal and other aquatic pathways. This paper is an inventory of available options and technologies (called 'Controls' or 'ANS Controls') that may be applied to prevent ANS transfer via aquatic pathways. These Controls serve as management measures for the Chicago Area Waterway System (CAWS) portion of GLMRIS, also referred to as Focus Area I. The ANS may also transfer between the basins via terrestrial and airborne means, including human assistance; however, these pathways fall outside of the scope of the GLMRIS authority. Options and technologies that address these pathways are not included in this paper.
