The RiverBend Duck Race is held at Raging Rivers Waterpark the end of May. The event doubles as a Business After Hours with networking among more than 800 RBGA members and community residents enjoying Raging Rivers Waterpark in Grafton.

Each year, nearly 2,000 plastic ducks are sold to compete in a race in the Lazy River water attraction, with the first 150 ducks through the finish line winning prizes such as Cardinals baseball tickets, restaurant gift certificates, baskets and much more. All prizes are donated from generous Riverbend businesses. Sponsorships are offered at various levels.
