USGS Water-Year Summary 2023
383226092054001 Jefferson City East
Ozark Plateaus aquifer system
Gasconade Dolomite
LOCATION - Lat 38°32'26.2", long 92°05'40.7" referenced to North American Datum of 1983, in SE 1/4 SE 1/4 SE 1/4 sec.23, T.44 N., R.11 W., Cole County, MO, Hydrologic Unit 10300102,
REVISIONS HISTORY - Revisions: Land-surface datum was revised to 704.41 ft NAVD88 on Oct. 4, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published in error as 691 ft NGVD29 from topographic map. Discrete water-level measurements referenced to NGVD29 and NAVD88 were revised, based on changes to the land-surface datum.
GROUNDWATER RECORDS
DATUM - Land-surface datum is 704.41 ft above North American Vertical Datum of 1988. Measuring point: DNR DCP platform shelf, 2.8 ft above land-surface datum, Mar. 26, 2009 to present.  
PERIOD OF RECORD - March 26, 2009 to present.
GAGE - March 26, 2009 to present, DCP with telemetry capability, and float and encoder installed as the water level recording and measuring devices.
REMARKS - Data from 03/26/2009 to 02/03/2010 has been processed by the USGS with limited field water level measurements (4 measurements) during the period to verify the recorded water levels. The record is good and accurate to +/- 0.05 ft. Data from 02/03/2010 to 08/19/2010 is good based on 5 water level measurements made during the period to verify the recorded water level data. The record is accurate to +/- 0.1 ft. Data from 08/19/2010 to 09/22/2011 is good based on 4 water level measurements made during the period to verify the recorded water level data. The record is accurate to +/- 0.05 ft. Appears the float occasionally sticks in the well, but when it becomes free the jump in the hydrograph is typically less than 0.1 ft. Data from 09/22/2011 to 08/12/2012 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. Data from 08/13/2012 to 08/05/2013 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 08/06/2013 to 01/26/2015 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 01/27/2015 3 to 07/18/2016 is good based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 07/19/2016 to 11/21/2016 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 11/22/2016 to 8/13/2017 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 08/14/2017 to 01/29/2018 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 01/30/2018 to 08/07/2018 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 08/08/2018 to 03/31/2019 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 04/01/2019 to 09/02/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft.

All further remarks can be found in RMS as of 09/03/2019.
