STUDY AREA BOUNDARY 365
393360 POTENTIOMETRIC SURFACE CONTOUR--Shows the altitude of the
potentiometric surface as defined by measured water levels in wells, altitudes of streams, springs, and topography. Contours are dashed where approximately located. Contour interval is 20 feet. Altitude in feet above National Geodetic Vertical Datum of 1929.
WATER-LEVEL MEASUREMENT SITES--Symbol gives location of site. Number is altitude of water level in feet above National Geodetic Vertical Datum of 1929. Sites outside the study area are shown if they were used to contour the potentiometric surface.
