Zebra Mussels and Management Implications for Endangered Freshwater Mussels on the Upper Mississippi River System

St. Croix River: Endangered Mussel Conservation - Zebra Mussel Control
Location/Description
|
Zebra mussels (Dreissena polymorpha) in the Upper Mississippi River are a significant threat to the continued survival of the endangered Higgins' eye pearly mussel (Lampsilis higginsii) and winged mapleleaf (Quadrula fragosa). Management of zebra mussels may include measures to manage dispersal of zebra mussels, reduce/manage zebra mussels already present and prevent future spread of zebra mussels and/or other exotics. Alternatives to be studied will include large- and small-scale alterations of the habitat conditions, closing portions of the system to recreational and/or commercial traffic, cleaning/coating technologies and barriers to prevent transport of zebra mussels.
The St. Paul District and the Engineer Research and Development Center in Vicksburg, Miss., are conducting the feasibility study in cooperation with the U.S. Fish and Wildlife Service; U.S. Geological Survey; National Park Service; Minnesota, Wisconsin and Iowa departments of natural resources; and Great Lakes Indian Fish and Wildlife Commission. Public and stakeholder meetings will be held with commercial shipping interests; recreational boating interests; and regional, county and local interests. Recommended management alternatives that fall outside the Corps' existing authorities would need to be implemented by others.

Status
|
A feasibility study for the management of zebra mussels in the St. Croix River and connecting Mississippi River pools began in 2006. A preliminary risk-based model will evaluate the most likely pathway for further zebra mussel invasion, estimate long-term population characteristics and identify sensitive areas and potential ecological consequences. The model is being refined in 2008 to develop and evaluate potential management actions, such as controlling dispersal in the St. Croix River basin and managing existing zebra mussel populations.
A decision support model is being developed to determine triggers and criteria for relocation and/or artificial propagation of winged mapleleaf mussels if zebra mussel control is only partially effective and/or determined to be not feasible. A workshop to implement a risk-based decision framework on this issue is scheduled for Oct. 22-23, 2008, in St. Paul, Minn.
|
Authority
|
The study is being conducted under the authority of Section 216 of the Flood Control Act of 1970, which authorizes investigations for modification of completed projects or their operation when found advisable as a result of significantly changed physical or economic conditions and for improving the quality of the environment in the overall public interest. The approved Section 905(b) reconnaissance report recommended a $2.2 million feasibility study at full federal expense to investigate zebra mussel control measures in the Upper Mississippi and Illinois waterways, including the St. Croix River. As stated in the final biological opinion for the operation and maintenance of the Upper Mississippi River 9-foot navigation channel, the study must comply with Section 7(a)(2) of the 1973 Endangered Species Act.
