Our History

The Sustainable Rivers Program began in 1998, when personnel from the Nature Conservancy approached the U.S. Army Corps of Engineers Louisville District to collaboratively develop an operations plan for the Green River Dam.

The Green River features one of the richest and most unique aquatic collections in the nation with more than 70 species of mussels, 150 species of fish, and a host species that live in its connected cave systems.

The dam was built in 1968 to help manage flood risk and provide water supply and recreation. Over time, the water regulating effects of the dam was impacting the health of many of the river’s aquatic species.

Working together, the two developed an operations plan for Green River Dam that could improve conditions for downstream ecosystems while continuing to meet human needs.
