USGS Water-Year Summary 2023
371125089445301 Delta
Mississippi River Valley alluvial aquifer
Holocene Alluvium
LOCATION - Lat 37°11'26.1", long 89°44'52.5" referenced to North American Datum of 1983, in SE 1/4 NW 1/4 SE 1/4 sec.08, T.29 N., R.12 E., Cape Girardeau County, MO, Hydrologic Unit 08020204,
REVISIONS HISTORY - Revisions: Land-surface datum was updated to 338.62 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 338 ft NGVD29 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.
GROUNDWATER RECORDS
DATUM - Land-surface datum is 338.62 ft above North American Vertical Datum of 1988. Measuring point: unknown, 1.8 ft above land-surface datum, Oct. 10, 1956 to present.  
PERIOD OF RECORD - November 1, 1956 to present
GAGE - As of November 1, 1956, water level measuring device is float and encoder. From April 26, 2000 to present, the water level recording device is a DCP with telemetry capability.
COOPERATION - All data furnished by Missouri Department of Natural Resources (MDNR); Record from November 1, 1956 to April 25, 2000 furnished from MDNR. Record from April 25, 2000 to present worked by USGS and MDNR.
REMARKS - Record from November 1, 1956 to April 25, 2000 is furnished by Missouri Department of Natural Resources (MDNR). Water level measurement made October 10, 1956 reported by driller when well was drilled. Three water level measurements were made by USGS personnel between October 1976 and November 1977. No water-level measurement data are available from the MDNR for this period because all data have been archived by MDNR. The record was manually processed from strip chart or digital recorder data. This record is considered fair. Data from April 26, 2000 to September 30, 2008 has been processed by the USGS with limited water level measurements (13 measurements) during the period. This record is considered fair. The record from October 01, 2008 to March 11, 2010 is good based on 7 water level measurements made during this period and is accurate to +/- 0.05 ft. Except for the period September 1, 2009 to January 20, 2010 which is fair caused by the float tape having trouble staying on the float wheel during this period. The record from 03/11/2010 to 06/23/2010 is good based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 06/23/2010 to 07/11/2011 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 07/11/2011 to 09/19/2012 is good based on 5water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 09/19/2012 to 08/18/2013 is good based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 08/19/2013 to 08/04/2014 is good based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.03 ft. The record from 08/05/2014 to 06/07/2015 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 06/08/2016 to 03/01/2017 is good based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 03/02/2017 to 09/06/2017 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.16 ft. The record from 09/07/2017 to 04/09/2018 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 04/10/2018 to 09/10/2018 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 09/11/2018 to 12/11/2018 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 12/12/2018 to 04/14/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 04/15/2019 to 05/21/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 05/22/2019 to 09/22/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft.
