We’re deeply grateful to our 2026 Big Fish Ball sponsors and donors whose generosity fuels our public policy and planning initiatives, educational programs, and hands-on river restoration work. Special thanks also go to the 2026 Honorary Committee for their steadfast support of our mission to protect and restore the Chicago-Calumet River system for all people, water, and wildlife.
