Records of water-level measurements in wells in Galveston County, Texas, 1894-1969.
Measurements in most observation wells in Galveston County, Texas, are made annually, but some measurements are made monthly, quarterly, or semiannually. A continuous measurement record is obtained at two locations where water-stage recorders are installed. If numerous measurements in a well were made during a short period of time, or if water-level data were obtained from a water-stage recorder, representative water levels were selected for publication. Water levels are referenced to land-surface datum.
