Lakes Online is an information and discovery website for people interested in rivers, lakes, and waterfront destinations. Its U.S. Rivers section helps visitors explore rivers by name and browse listings across states. The site also features information about paddling opportunities, including the Chattahoochee River Whitewater course between Columbus, Georgia, and Phenix City, Alabama, with a link to the course’s website.

For river users, Lakes Online explains whitewater classifications from Class I, suitable for easier paddling, through Class VI, described as unrunnable. It also presents a map of current daily streamflow conditions, with percentile indicators that help readers interpret river flows in context. A ranked table of North America’s longest rivers provides comparative reference information.

Beyond river resources, the wider site covers lakes, marinas, coastal towns, waterfront aerials, seaplane bases, boat shows, fishing tournaments, and lake news. Visitors can sign up for email alerts featuring lake-related articles, videos, and podcasts from around the web.
