Activate Big Fish Ball Support for the River

February 20, 2025

There are many ways to support one of our most special fundraising events of the year – The Big Fish Ball on April 17. The elegant evening brings together a key community of Friends’ supporters, partners, and civic leaders in celebration of our work to protect and restore the Chicago-Calumet River system.

This year the Big Fish Ball will be an activating Earth Day on the River cruise aboard the Odyssey Chicago River, and all sponsors will enjoy special April Earth Month employee engagement activities to make a direct and positive impact on the health of the 156-mile river system and its wildlife.

Sponsor packages include cruise tickets and in-the-field and educational opportunities for your team to engage in Earth Month activities with Friends professional staff. It’s never too early to make a donation to support Friends. 

Learn how your gift supports the river system. 

Another way you can support the Big Fish Ball is by purchasing a program book ad or a Jumbotron ad. Program ads are available for $550 for a full page, and Jumbotron ads are available for $450 per slide.

Visit our sponsorship webpage to learn more about Big Fish Ball sponsorship opportunities or contact our Director of Development, Annie Hanrahan, at ahanrahan@chicagoriver.org, or (312) 939-0490, ext. 19. We are also looking for volunteer support to help make the Big Fish Ball a wonderful experience for all.

We truly hope we can count on you to support and come to this most important fun and fundraising event.
