Green River: Fast Facts

For more than a decade, the Conservancy has worked with landowners, farmers, non-profit organizations and government agencies to achieve several milestones related to improving water quality and habitat within and around the Green River.

9,230 square-mile watershed

Central Kentucky, including the upper Green River watershed, major tributaries (Nolin, Rough, and Barren rivers and Pond Creek), wetlands complexes in the lower Green River and Mammoth Cave National Park

What’s At Stake
The Green River gives life to more species of plants and animals than any other Ohio River tributary—especially in an unhindered 100-mile stretch that flows from the Green River Reservoir Dam and through Mammoth Cave National Park. This stretch harbors one of the most diverse assemblages of fish and freshwater mussels in the United States.
