The objectives of this study are: 1. Determine the current status of endangered mussels in the Green River from the Green River Dam (GRD) downstream through Mammoth Cave National Park; 2. Determine whether modifications made to the discharge regime from the Green River Dam are enhancing mussel recruitment; 3. If deemed necessary, establish captive breeding populations of ringpinks, clubshells, and northern riffleshells mussels; 4. Determine various aspects of the life histories of endangered species present; and, 5. As necessary, make recommendations to the U.S. Army Corps of Engineers, and the U.S. Fish and Wildlife Service regarding further modifications to the discharge regime of the GRD, and the need to propagate endangered mussels.
