Stoni Hawkins, left, and Terriyah Moss play in Starkweather Creek at the Olbrich Park boat launch in Madison, Wis., on Aug. 16, 2021. Though Terriyah and her family often boat on the lakes, they rarely swim in Madison’s waterways due to pollution. "I have always heard there were issues with the lakes here in Madison, Wisconsin, but I guess I didn’t realize the extent of the danger of them," said Terriyah’s mother, Tammy Moss.
