Asian Carp Response in the Midwest
Fish Barrier Technologies
- Electrical Dispersal Barrier
- The use of electric fields generated through electrodes secured to the bottom of the Chicago Sanitary and Ship Canal to deter the inter-basin movement of fish. Agency Lead: U.S. Army Corps of Engineers.
- Adult Barrier at Eagle Marsh – Indiana
- Installation of a 10 foot high, trenched, chain link fencing across a portion of Eagle Marsh designed to prevent the movement of large adult fish during flood events. The structure includes water-level gages to alert responders to the presence of water levels that indicate the need to inspect for the presence of adult Asian carps. Agency Leads: Indiana Department of Natural Resources, Natural Resources Conservation Service and U.S. Geological Survey.
- Des Plaines River Bypass Barrier – Illinois
- A 13-mile physical barrier on land, consisting of mesh fence and jersey barriers, designed to prevent fish from potentially bypassing Chicago's electric dispersal barriers via overland flow from the Des Plaines River during flood events. Agency Lead: U.S. Army Corps of Engineers.
- Great Lakes and Mississippi River Interbasin Study (GLMRIS)
- Study of available options and technologies to prevent the transfer of aquatic nuisance species between the Great Lakes and Mississippi River basins via aquatic pathways. Agency Lead: U.S. Army Corps of Engineers.
- Mobile Electrical Barrier
- Assessment of Closure Options – Ohio
- Assessment of closure options for Little Killbuck Creek, Ohio Erie Canal, Grand Lake St Mary’s and Mosquito Lake. Agency Leads: Ohio Department of Natural Resources, Natural Resources Conservation Service and TetraTech.
- Lock and Dam 1 “Sweeping” Electrical Barrier – Minnesota
- Development of a modified electrical barrier. Agency Lead: Minnesota Department of Natural Resources.
- Small Stream Electrical Barriers – Minnesota
- Development of small stream electrical barriers. Agency Lead: Minnesota Department of Natural Resources.
- Bubble-Acoustic Barriers – Canada
- Testing the impact of bubble-acoustic barriers. Agency Lead: Fisheries and Oceans Canada.
