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.
The 2026 Big Fish Ball will be held on Thursday, April 16, from 6-8 p.m. aboard the Odyssey Chicago River. Learn more about how you can support our event in April 2026 today by contacting Annie Hanrahan at ahanrahan@chicagoriver.org.
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.
