Grace Graham ’13 and Prof. Sue Swanson Describe The Abundance And Significance Of Wisconsin’s Springs

Grace Graham’13, geologist with Wisconsin Geological & Natural History Survey, and Professor of Geology Sue Swanson discuss their work locating and monitoring springs around the state.

How many springs are there in Wisconsin? Where is the largest spring in the state? And what conditions control their formation? A spring is a natural point of flowing groundwater at the Earth’s surface. Wisconsin is home to over 400 springs that discharge over 100,000 gallons of water per day. While they do not produce enough water for public drinking water supplies, they supply fish hatcheries and supplement agricultural activities. Springs are also ecologically important, creating small specialized habitats with nearly stable temperatures and year-round vegetation. Watch the podcast.
