Katie Callahan serves as the Director of the Clemson University Center for Watershed Excellence, designated a Center of Excellence by the US EPA Region 4 and the SC Department of Health and Environmental Control (SC DHEC). The Center’s core responsibility is to develop science-based outreach tools that engage stakeholders in greater and improved watershed management in SC. The Center’s largest current project is the development and implementation of SC Adopt-a-Stream, our state’s first citizen science water quality and ecosystem monitoring program from the mountains to the coast.

Katie has served locally on the board of Friends of the Reedy River since 2017 as Technical Committee member, Board Chair, and Immediate Past President. In 2021, Katie was appointed by the Governor to serve on the board of Palmetto Pride, our statewide agency devoted to litter prevention.

Katie is passionate about the outdoors, and everything water fills her cup. She enjoys exploring our beautiful, natural world with her daughters and family. A champion for women in science, she began an initiative known as Women in Water Outdoors that seeks to build connection and confidence for women in the water industry through outdoor adventure and professional development opportunities.

Katie became a Certified Facilitator with Leadership Strategies in 2022, acknowledging the need to have more constructive conversations about the future of our waterways and how each individual has a unique connection and perspective about water. Katie also graduated Leadership Greenville in 2021, where her project team built the first-ever home for women and their children experiencing homelessness in the upstate of South Carolina.
