73°42'34" referenced to North American Datum of 1927,
Rensselaer County, NY, Hydrologic Unit 02020006, at East
Greenbush.
WELL CHARACTERISTICS.--Depth 79 ft. Upper casing diameter 6 in; top of first opening 78 ft, bottom of last opening 80 ft. Well filled in from original depth of 80 ft, cased to 78 ft (screen, 78 ft to 80 ft).
DATUM.--Land-surface datum is 252.01 ft above North American Vertical Datum of 1988. Measuring point: Top of shelter shelf, 2.89 ft above land-surface datum, Aug. 6, 2012 to Jun. 16, 2022; Top of shelter shelf, 2.91 ft above land-surface datum, Jun. 16, 2022 to present.
PERIOD OF RECORD.--October 1982 to August 1995, April 2003 to current year.
REVISIONS HISTORY.--Groundwater levels for the period Mar. 25, 2019 at 9:15 to July 10, 2019 at 15:30 were revised on Apr. 28, 2020, because an incorrect tape-down measurement was done and subsequent incorrect correction was applied.
GAGE.--Water-stage recorder--15 minute; periodic manual measurements by USGS personnel.
REMARKS.--Water level may be affected by nearby pumping. Well was drilled October 1982 as a replacement for 423532073423701 (local number Re 701), which was located about 300 ft southwest and 15.8 ft lower in land-surface datum, and had a period of record from March 1961 to May 1980. The wrong measuring point value was used from November 1982 through the 1985 water year. A -.20 ft correction should be applied to all published record prior to the 1985 water year. Satellite water-level telemeter at station.
EXTREMES FOR PERIOD OF RECORD.--Highest water level recorded, 32.86 ft below land-surface datum, June 4, 5, 6, 7, 8, 9, July 11, 1984; lowest water level recorded, 41.93 ft below land-surface datum, Jan. 23, 24, 1986.
