On Thursday, June 05, the Ohio River Basin Alliance, the National Wildlife Federation, and the University of Louisville’s Christina Lee Brown Envirome Institute released the Ohio River Basin Restoration and Protection Plan, a comprehensive report that recognizes the numerous environmental improvements in recent decades while calling attention to existing and emerging threats that command a basin-wide, collaborative effort to ensure drinking water, healthy ecosystems, and vibrant economies throughout the region. The report draws from the expertise of a diverse technical committee, including local, state, and regional agencies, academic institutions, industry, and non-governmental organizations, along with input from our Tribal partners and residents in the region who participated in community input sessions.

After a 65 day public comment period, nearly 1,000 responses to the report were gathered. Now, Ohio River Basin Alliance leadership are integrating public feedback into the next and final iteration of the report.


Thank you for your feedback!
