A survey of freshwater mussels of the Upper Mississippi River drainage was conducted during the summer and autumn of 1977. Over 8,000 living specimens were gathered and examined during surveillance of more than 40 actual and/or potential dredging sites in the Minnesota and St. Croix Rivers and in almost 20 Upper Mississippi River pools. Dredging and associated activities to maintain the 9-foot navigation channel has caused local mortality of mussels, including endangered species. There are other factors having far greater adverse impact, including wastes from the cities of Minneapolis and St. Paul, agricultural runoff, impoundment of the Upper Mississippi River and encroachment by Corbicula fluminea, the Asiatic Clam. The outlook for a continuing ecosystematic and commercial mussel resource appear to be good. Even certain endangered species (e.g. Lampsilis higginsi) are likely to survive if appropriate measures are taken.

The primary objectives of the study were to characterize the present mussel fauna, to compare it to the fauna existing before the 9-foot Navigation Channel Project, and to determine the influence(s) upon mussels by practices of the District's Operations and Maintenance (O & M) activities. The study area was the main channel and main channel borders of the UMR itself from Head of Navigation at river mile (RM) 857.8 in the Twin Cities, Minnesota, to Locks and Dam 10 at Guttenberg, Iowa (RM 615.1), and the lowermost (Corps-maintained) reaches of the black (at La Crosse, Wisconsin), Minnesota, and St. Croix rivers. More than 100 formal Sites were thoroughly surveyed (usually by brailing), and about a dozen locations were investigated cursority. Over 10,000 living mussels were collected and examined, including a few of the Endangered Lampsilis higginsi.

Large river systems are valuable national resources that provide numerous benefits to travel, shipping, recreation, and fish and wildlife. However, efforts to expand one of the uses frequently come in direct conflict with one or more of the othersThis guide attempts to bring together all scientific data that are available on techniques that have been or can be used to offset or reduce the impacts of development and maintenance of Upper Mississippi River System or other large river systems. Decision makers are thus provided an objective descriptin of options now at their disposal when they attempt to weigh the merits of defects associated with a particular action.
