Wisconsin is rich in water, both groundwater and surface water.
This section describes Wisconsin’s aquifers, springs, sinkholes, and karst. Here you can learn about the network of wells that monitor groundwater levels throughout the state and where you can find well records dating back to 1936. You’ll also find videos of the many public talks our staff have given on various aspects of Wisconsin’s water resources and blog posts about our water-related research.
