WELL CHARACTERISTICS - Depth 26.65 ft. Upper casing diameter 1.5 in; top of first opening 26.15 ft, bottom of last opening 28 ft. Well was drilled with a PVC casing, currently 2.34 feet above land surface.

DATUM - Land-surface datum is 88.72 ft above North American Vertical Datum of 1988. Measuring point: 2.55 old MP noted (new 2.35 on Sep 04, 2014, new GW sensor), 2.55 ft above land-surface datum, Apr. 16, 2014 to present; Undefined, 2.35 ft above land-surface datum, Sep. 3, 2014 to present. MP is 2.34 feet above land surface from GPS total station on Oct 15, 2010

PERIOD OF RECORD - Ground water level measurements on Sep 15, 2010 and April 16, 2014 (well pumped), Continuous record Oct 08, 2010 to Oct 03, 2011 (Depth Below Land Surface only) and Sep 03, 2014 to current (except floods)

GAGE - A DA 522 plus DCP housed in a 3 by 3 by 2-foot fiberglass Hoffman box is fixed to a wooden platform, about 3 feet above ground, located on downstream right bank near piezometer at Big Sunflower Diversion Canal (323045909484300). A KPSI submersible pressure transducer connects the gage to the well.

COOPERATION - This well is maintained in cooperation with the U.S. Army Corps of Engineers, Vicksburg District (Funding partially lapsed in March of 2018, tentatively re-funded for 2019 Water Year) as part of the Lower Mississippi River Delta Alluvial GW/SW interaction project.
