Water Level Data and Hydrographs
View Water Level Data
The WRD Groundwater Information System (GWIS) allows you to explore subsurface data managed by the state. The GWIS is a database housing information pertaining to “groundwater sites”, which are dominantly a cross-referenced subset of the well log database (approximately 7%). In addition to these well locations, the GWIS also includes some spring locations, outcrop sample locations, and stratigraphic section locations.

Water-level plots for WRD observation wells. Includes wells in the state observation well net (generally measured quarterly by regional or district office staff) and other observation wells that were established for various ground water projects.
