Impact Report
At Friends of the Big Sioux River, 2025 was a momentous year full of public outreach events, water quality monitoring, advocacy work, and river clean-ups. Read our full impact report below to see all that we accomplished in 2025. We look forward to advancing these crucial water quality improvement efforts throughout the Big Sioux River watershed in 2026!
We made great strides in 2025, but that was only possible thanks to the support of our generous donors and volunteers. After reading the 2025 Annual Report, we hope you feel called to support our 501(c)(3) nonprofit by attending one of our community outreach events, participating in a river clean-up, or providing a monetary donation. From the bottom of our hearts, we thank you for your support of Friends of the Big Sioux River!
