USGS Water-Year Summary 2023
364818094185302 Neosho Ozark Aquifer
Ozark Plateaus aquifer system
Cotter-Jefferson City Dolomite
LOCATION - Lat 36°48'17.7", long 94°18'53.1" referenced to North American Datum of 1983, in NW 1/4 SE 1/4 sec.18, T.24 N., R.31 W., Newton County, MO, Hydrologic Unit 11070207,
REVISIONS HISTORY -
Revisions: Land-surface datum was updated to 1,262.94 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 1,265 ft NGVD29 from a topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.

The period from 08/28/2008 to 09/30/2008 was modified after it was previously approved. A prorated correction from -0.04 to -0.09 ft was applied to the period 08/28/2008 to 02/23/2009 instead of a prorated correction from zero to -0.09 ft which was previously used for this period. It was noticed the gage was not set to the water level measurement on 08/28/2008 and a correction was needed from the start of the period. This changed the previously approved data by -0.04 ft on 08/28/2008 to -0.03 ft on 09/30/2008.

REMARKS -

Data from 07/17/2007 to 09/30/2008 has been processed by the USGS with limited field water level measurements (5 measurements) during the period to verify the recorded water levels. This record is considered good and accurate to +/-0.1 ft. Data from October 01, 2008 to August 17, 2010 is good based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 08/17/2010 to 08/15/2011 is good based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 08/15/2011 to 07/24/2012 is good based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 07/25/2012 to 10/08/2013 is good based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 10/09/2013 to 12/08/2014 is fair based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. Data from 01/06/2015 to 04/24/2016 is fair based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. Data from 04/25/2016 to 10/04/2016 is good based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 10/05/2016 to 08/15/2017 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 08/16/2017 to 01/30/2018 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 01/31/2018  to 09/17/2018 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.20 ft. Data from 09/18/2018 to 01/08/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft. Data from 01/09/2019 to 06/25/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft. Data from 06/26/2019 to 12/10/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft.
