Fully fund the Chicago San-Ship Canal barrier and the sea lamprey program. Study options for permanent hydrological and/or biological separation of the Great Lakes and the Mississippi River system. Consider measures to prevent the spread of AIS via neighboring canals and waterways. Consider barrier and canal closings when appropriate. Prohibit development of new cross-drainage basin connections. Address issues of AIS introduction and spread related to flooding, dam removal/culvert construction, and potential fish passage projects. Develop monitoring plans.
The Chicago Sanitary & Ship Canal forms a unique, man-made link between the Great Lakes drainage basin and the Mississippi River drainage basin. Today, this vital navigation corridor also provides AIS access between these two basins. It was determined that design and construction of a barrier demonstration project to prevent or reduce the dispersal of non-indigenous aquatic species between the Great Lakes and the Mississippi River drainage basins was essential. The barrier was originally authorized as a temporary project intended for research of the effectiveness of electric barriers. A second permanent dispersal barrier was needed to provide continued protection against nuisance species. The National Invasive Species Act of 1996 authorized the Army Corps of Engineers to carry out the demonstration study. This authorization expired in 2002. In 2007, Congress approved the Water Resources Development Act (WRDA) of 2007 which provided authorization for USACE to complete construction and operate and maintain the barrier system at full federal cost.
P.L. 101-636, as amended in 1996 (NISA) and P.L. 110-114 (WRDA)
Reauthorizes and amends the Nonindigenous Aquatic Nuisance Prevention and Control Act of 1990 (P.L. 101-646). Authorizes several new Great Lakes invasive species programs including a project to develop an electric dispersal test barrier to prevent the dispersal of non-indigenous
aquatic nuisance species between the Great Lakes and Mississippi River basins through the Chicago Sanitary and Ship Canal; and a program to demonstrate technologies and practices to prevent aquatic nonindigenous species from being introduced into and spread through ballast water in the Great Lakes and other waters of the United States.
