Big Fish Ball
Support Friends next Earth Month at our Largest Annual Fundraiser
The Big Fish Ball engages community partners, corporate sponsors, educators, and more to support Friends of the Chicago Rivers mission: to protect and restore the Chicago-Calumet River System for all people, water, and wildlife.

We’re deeply grateful to our 2025 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 2025 Honorary Committee for their steadfast support of our mission to protect and restore the Chicago-Calumet River system for all people, water, and wildlife.
