USGS Ground Water Watch (formerly Ground Water Observation Network)

In cooperation with

Ground Water Watch is a distributed national water database that receives Wisconsin ground water data. Surface water, ground water, and water quality data are collected and rolled up from our local, distributed databases into the national information system, Ground Water Watch.

Because Wisconsin data is automatically uploaded into the national data interface, the local Ground Water Observation Network webpages here were discontinued in June 2008 to use the improved data interface at Ground Water Watch and to eliminate redundant data sources.

All data previously viewed here is maintained in Ground Water Watch. Hydrographs previously posted here can still be accessed. Contact Jason Smith with questions on this interface changeover.
