USGS Water-Year Summary 2023

375429092300701 Ozark Fisheries

Ozark Plateaus aquifer system
Cambrian System

LOCATION - Lat 37°54'30.0", long 92°30'06.9" referenced to North American Datum of 1983, in SE 1/4 SE 1/4 sec.30, T.37 N., R.14 W., Camden County, MO, Hydrologic Unit 10290109,

REVISIONS HISTORY -
Revisions: Land-surface datum was revised to 827.58 ft NAVD88 on Oct. 4, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published in error as 815 ft NAVD88 from topographic map. Discrete water-level measurements referenced to NGVD29 and NAVD88 were revised, based on changes to the land-surface datum.

The data from 09/21/2001 to 04/12/2010 was modified after it was previously set to 'Approved'. It was discovered that a measuring point height correction of 1.0 ft was needed for the period but was not previously applied.

REMARKS -

Data from 09/22/2001 to 09/30/2008 has been processed by the USGS with limited field water level measurements (12 measurements) during the period to verify the recorded water levels. This record is considered good. Data from 10/01/2008 to 04/12/2010 is good based on 9 water level measurements made during the period to verify the recorded data. Because the float has a tendency to stick in the well, there are frequent 'jumps' in the data when the float breaks free. This results in the data being accurate to +/- 0.2 ft. The record from 04/13/2010 to 10/27/2010 is good based on 3 water level measurements made during the period to verify the recorded data. The float still has a tendency to stick in the well causing data 'jumps' on the hydrograph. The accuracy of this period is +/- 0.2 ft. The record from 10/26/2010 to 10/19/2011 is good based on 4 water level measurements made during the period to verify the recorded data. The float still has a tendency to stick in the well causing data 'jumps' on the hydrograph. The accuracy of this period is +/- 0.2 ft and this is primarily caused by the float sticking. The record from 10/20/2011 to 09/11/2012 is good based on 4 water level measurements made during the period to verify the recorded data. The float still has a tendency to stick in the well causing data 'jumps' on the hydrograph. The accuracy of this period is +/- 0.2 ft and this is primarily caused by the float sticking. The record from 09/12/2012 to 11/05/2013 is good based on 6 water level measurements made during the period to verify the recorded data. The float still has a tendency to stick in the well causing data 'jumps' on the hydrograph. The accuracy of this period is +/- 0.2 ft and this is primarily caused by the float sticking. The record from 11/06/2013 to 03/24/2014 is fair 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 03/25/2014 to 03/21/2016 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 03/22/2016 to 11/07/2016 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 11/08/2016 to 03/22/2017 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 03/23/2017 to 10/10/2018 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 10/11/2018 to 04/22/2019 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 04/23/2019 to 09/09/2019 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 09/10/2019 to 12/02/2019 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft.
