Description:
Groundwater elevation change from Spring 2011 to Spring 2016.

These layers show changes in groundwater levels over time. Each point shows the calculated difference between the measured groundwater levels from the selected time period. The change in groundwater level is plotted on the map only if a measurement exists in both time periods at a well.

The colored points in the measurements layer show the location of all wells where the groundwater level change is determined. The contours and color ramp layers approximate change in the groundwater levels for the unconfined to uppermost semi-confined aquifers and is based on a subset of all of the measurement points, which were selected based on measurement date and well construction information (where available).
