Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth undefined. Upper casing diameter undefined; top of first opening undefined, bottom of last opening undefined. GW monitoring well Number 1 was drilled with a 2-inch PVC casing to a depth of 29.5 feet below land surface (LSD datum = 107.86). Number 2, QW monitoring, well was drilled to a depth of 39.5 feet below land surface. Bottom of Number 1, GW monitoring well, 1-foot screen is at 29.25 feet below land surface. Bottom of Number 2, QW monitoring well, 5-foot screen is 39.25 feet below land surface. Top of Number 1, GW monitoring, well casing is 2.00 feet above land surface.
DATUM - Land-surface datum is 107.86 ft above North American Vertical Datum of 1988. Measuring point: Undefined, 2.00 ft above land-surface datum, Mar. 11, 2015 to present. Measuring point (MP 1) is at top of 2-inch PVC well casing, 2.00 feet above land surface just downstream of gage platform.
PERIOD OF RECORD - Oct 01, 2014 to current (Jul 03, 2014 install to Sep 30, 2014 not published).
GAGE - A 3 by 3 by 2-foot Hoffman box fixed to a wooden platform about 3 feet above ground is located on right bank just downstream of 07288847, Steele Bayou near Glen Allen, Mississippi. A KPSI submersible pressure transducer connects the gage to the well just downstream of the platform Number 2 Water Quality monitoring well is capped, just downstream of Number 1 GW Level monitoring well. A Design Analysis 522 plus DCP connected to a KPSI submersible pressure transducer set to a 15-minute scan interval is housed at the Hoffman gage house shelter/platform. New KPSI submersible pressure transducer was installed on Sep 28, 2017.
COOPERATION - This well is maintained in cooperation with the U.S. Army Corps of Engineers, Vicksburg District (Funding lapsed in March of 2018) as part of the Lower Mississippi River Delta Alluvial GW/SW interaction project.
REMARKS - Oct 01, 2014 - current. Groundwater level and temperature records are good. Missing periods due to equipment malfunctions are not estimated or gap filled.
PERIOD OF DAILY RECORD - Oct 01, 2014 to current (Jul 03, 2014 install to Sep 30, 2014 not published).
