Be part of the Mill Creek's comeback!


Visit our new Mill Creek Alliance website to see details about how you can get involved




As responsible fiscal stewards, we operate on a lean budget with a streamlined staff to maximize improvement in the Mill Creek Watershed. Your financial donation or contribution of time as a volunteer helps us better serve you and achieve results that further our efforts to create a culture of stewardship around the Mill Creek, our shared water resource.

Because clean water matters, we encourage individuals, political jurisdictions, businesses, and nonprofit organizations to invest in the Mill Creek through charitable giving. Your financial support provides critically needed operational funding that allows us to complete our mission-driven work. All contributions are tax-deductible.


Alternatively, you may mail your contribution to the new Mill Creek Alliance office: 

Mill Creek Alliance (previously Mill Creek Watershed Council of Communities)
1662 Blue Rock Street
Cincinnati, OH 45223
