Well Hydrographs, Spring 2014

Below are links to select well hydrographs within each major groundwater basin showing historic groundwater levels through Spring 2014. Each well is labeled as follows:

Well Number: This is a number assigned by the State, for instance 14N-09W-32M1. The well number identifies the well by Township, Range, Section number and by lot within the section (there are 16 lots).

Reference Point Elevation: This is the elevation of the reference point the groundwater is measured from. It is normally several inches to two feet above ground elevation.

Water Surface Elevation: This is the groundwater level measured within each well. Low data points may be due to drought or due to groundwater level depression due to well pumping at the measured well or at nearby wells.

These hydrographs only tell part of the story of each groundwater basin, as long term groundwater conditions due to changing water use and aquifer conditions can have a substantial effect the average spring and fall levels. Conditions are also different within different areas within a basin. You can view a report summarizing groundwater conditions here and well location maps here.
