An Evaluation of Freshwater Mussels in the Lower Ohio River in Relation to the Olmsted Locks and Dam Project: 1998 Studies

Abstract

Surveys were conducted in August 1998 to assess community characteristics, population demography of dominant species, status of endangered species, and characteristics of nonindigenous populations of freshwater bivalves in the lower Ohio River (LOR). Data will be used to analyze ecological effects of construction and operation of a new lock and dam at River Mile (RM) 964.4. Primary focus has been on a prominent mussel bed just downstream of the project at Olmsted, Illinois. Studies have shown that this mussel bed extends approximately from elevation 278 ft nearshore to 267 ft farshore. Moderate (20-50 individuals per square meter) or high density (>50 individuals per square meter) assemblages of mussels tend to be at more central elevations on the bed from approximately RM 966.4 to 968.3.
