Activity 5 of the Cumberlandian Mollusk Conservation Program (CMCP) evaluated physical conditions at 15 study reaches in the Tennessee River Valley. This was part of a multiphase project to study several environmental factors as they relate to freshwater mussels. Areas of the Buffalo and Clinch Rivers, Copper Creek, and the Duck, Elk, Nolichucky, North Fork Holston, Paint Rock, and Powell Rivers were surveyed and measured to determine physical, hydrologic, hydraulic, substrate, and suspended sediment conditions. Data collected over a two-year period are summarized and presented in graphic and tabular form to facilitate the classification of river reaches according to habitat suitability for the endangered mussels. The effect of instream structures (low-head dams) on the nature and stability of the downstream substrates was studied. This task was conducted to determine if these dams alter the downstream physical environment to provide favorable conditions for mussel survival.
