Between 2014 and 2017, Wisconsin's springs were identified, mapped, and surveyed
by the Wisconsin Geological and Natural History Survey.
This inventory provides detailed descriptions of 415 springs with flow rates of at least 0.25 ft3/second. Each site includes photos, a site sketch, graphs of water quality and spring bed materials, plus the full set of data collected. To learn more about the project, see An Inventory of Springs in Wisconsin.
