Effects of Increased Commercial Navigation Traffic on Freshwater Mussels in the Upper Mississippi River; 1992 Studies.
Abstract
In accordance with the Endangered Species Act, Section 7, Consultation, personnel from the U.S. Army Engineer District, St. Louis, and the U.S. Fish and Wildlife Service (USFWS) determined that a monitoring program should be initiated in the upper Mississippi River to assess the effects of existing and projected future increased traffic levels on freshwater mussels including the endangered Higgins eye mussel Lampsilis higginsi. Concern had been expressed by the USFWS and other agencies that projected increases in commercial traffic resulting from completion of the Melvin Price Locks and Dam, Second Lock Project (formally known as Locks and Dam 26) at Alton, IL, could negatively affect freshwater mussels. In 1988, the St. Louis District contracted with the U.S. Army Engineer Waterways Experiment Station (WES) to initiate these studies. The purpose of the 1988 studies was to identify sample sites for future work. This report describes results of the fourth full study year, which took place in 1992.
