GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 57.14 ft. Upper casing diameter 5.44 in; top of first opening 16.55 ft, bottom of last opening 57.14 ft. Domestic water-supply well, not currently in use.
DATUM - Land-surface datum is 1,201.04 ft above North American Vertical Datum of 1988. Measuring point: Mark on wooden base of instrument shelter. MP altitude surveyed 10/2007., 1.05 ft above land-surface datum, July 24, 1996, to present. Land surface datum is accurate within 0.1 ft.
PERIOD OF RECORD - Manual measurement on February 27, 1996 to current year. Continuous measurements July 24, 1996 to current year.
GAGE - Pressure transducer and data logger (records hourly).
COOPERATION - Groundwater-level data is collected as part of a USGS cooperative study with the Geauga County Planning Commission and the Board of County Commissioners. The long-term groundwater monitoring network in Geauga County consists of 30 wells. The purpose of the water-level study is to determine whether fluctuations in water levels represent consistent, long-term trends caused by human activity or are predominantly the result of seasonal and annual variations in recharge.
EXTREMES FOR PERIOD OF RECORD - Minimum daily low, 23.68 ft below land-surface datum, June 3, 1997; maximum daily low, 28.84 ft below land-surface datum, September 29, 2016 (this water-level was affected by nearby pumping).
