EFFECTS OF INCREASED COMMERCIAL NAVIGATION TRAFFIC ON FRESHWATER MUSSELS IN THE UPPER MISSISSIPPI RIVER: 1993 STUDIES
In 1988, The U.S. Army Engineer District, St. Louis, initiated a monitoring program to analyze the effect of commercial navigation traffic on freshwater mussels, especially the endangered Lamsilis higginsi, in the upper Mississippi River (UMR). Preliminary studies were conducted in 1988, and detailed studies were initiated in 1989 and will continue until 1994. In August-September 1993, freshwater mussels were collected using qualitative and quantitative methods in the main and east channel of Pool 10 near River Mile 635.2. The sampling program was reduced in 1993 because of high water throughout most of the UMR. This report provides results of the 1993 studies.
