Evaluating Groundwater Elevations

For evaluating groundwater elevations, ten wells were selected from an extensive network as being representative of various parts of the SGA area. At these wells, threshold values were established at elevations that SGA would not want to see groundwater elevations drop below. These values were based on a review of past groundwater elevation data. The primary intent of the wells is to ensure that groundwater elevations will not drop below historic lows. The wells are located to ensure monitoring at boundaries with other groundwater management agencies, near areas of the surface water/groundwater interface, and in areas that could potentially experience subsidence.

The locations of these wells, referred to as Threshold Wells, are shown below.
