Asian Carp Barrier System Upper Mississippi River
Description of Problem
|
Invasive species are non-native plants and animals that have been introduced to ecosystems, become abundant and persist, displacing native species. Invasive species have significant ecological and economic impacts in this region. We deal with these species as part of our land and water stewardship at Corps projects, in planning new projects, and in ecosystem restoration efforts.
|
Asian carp are invading the Upper Mississippi River. Plankton-feeding bighead and silver carp escaped from aquaculture. They grow rapidly up to 60 pounds. Both species have established populations in the Upper Mississippi River as far north as Pool 18. Silver carp leap out of the water when startled, creating a safety hazard for recreational boaters. Mollusk-eating black carp also escaped from aquaculture in Arkansas, Missouri, and Louisiana and threaten native mussels in the Upper Mississippi River, although no known naturally reproducing populations of this species are in the river.
|
Status
|
The interbasin connection at the Chicago Sanitary and Ship Canal is a key to limiting the introduction of additional invasive aquatic species from the Great Lakes. An electrical fish barrier was constructed on the canal near Romeoville, Illinois, in 2001; a second nearby electrical barrier was constructed in 2006. The Water Resources Development Act of 2007 authorized the Barrier II element of the project and a feasibility study to examine the ways to prevent the spread of aquatic nuisance species between the Great Lakes and the Mississippi River basin.
|
We examined the technologies for limiting upriver invasion of Asian carp as part of the Upper Mississippi River-Illinois Waterway Navigation Study. A sound projection array/acoustic bubble curtain system could be installed at an Upper Mississippi River dam to test effectiveness in deterring fish from moving through the navigation locks. Even if such a system could deter fish from entering the locks, the barrier would be only temporary at best because Asian carp can swim upriver through the dam gates during larger floods.
Upper Mississippi River System lockmasters can keep the upper lock miter gates closed when vessels are not transiting the locks to limit upriver passage of Asian carp through the locks.
We assisted the Minnesota Department of Natural Resources in a feasibility study on ways to slow the northward invasion of Asian carp in the Mississippi River. Action to slow the invasion is needed soon, or the fish will establish populations in the upper river.
|
Authority
|
The Section 5016 of the Water Resource Development Act of 2007 authorized a study and implementation of an aquatic nuisance species deterrent barrier project on the Upper Mississippi River for $4,000,000. Lock and Dam 11 in the Rock Island District is a likely site for a fish barrier demonstration project.
