USGS Water-Year Summary 2019
381652093215501 Warsaw
Ozark Plateaus aquifer system
Cambrian, Upper
LOCATION - Lat 38°16'51.2", long 93°21'55.1" referenced to North American Datum of 1983, in NE 1/4 NE 1/4 NW 1/4 sec.04, T.40 N., R.22 W., Benton County, MO, Hydrologic Unit 10290109,
REVISIONS HISTORY - The data from 10/18/1979 to 11/18/2009 was modified after it was previously set to 'Approved'. It was discovered that a measuring point height correction of 3.2 ft was needed for the period but was not previously applied.
GROUNDWATER RECORDS
DATUM - Land-surface datum is 747 ft above National Geodetic Vertical Datum of 1929. Measuring point: Undefined, 3.2 ft above land-surface datum, Jul. 20, 1979 to present.
PERIOD OF RECORD - October 18, 1979 to present.
GAGE - Stevens model A-35 chart recorder installed July 20, 1979. Stevens model 7001 digital recorder installed October 1, 1987. July 26, 2000 to February 28, 2006; DCP with float, encoder, and telemetry capability was installed as the water level recording device. March 1, 2006 to present DCP with vented, submersible pressure transducer and telementry capability.
COOPERATION - Data furnished by Missouri Department of Natural Resources (MDNR), except for the period from 10/01/1989 to 09/30/1991 which was provided by the USGS. Record from October 18, 1979 to July 25, 2000 furnished from MDNR, except for the period from 10/01/1989 to 09/30/1991. Record from July 25, 2000 to present, processed by USGS and MDNR.
REMARKS -

The furnished record from October 18, 1979 to February 5, 1986 appears to be good.

The record from February 6, 1986 to October 1, 1991 (period where there is raw field data to review) is rated good, except for the period from August 26, 1987 to May 28, 1988 which is rated fair. This record is rated down slightly because there was descrepancy between the water level measurement and A-35 pen setting.

The furnished record from October 1, 1991 to July 25, 2000 appears to be good except for the 1994 water years which does not seem to follow the normal recharge - drawdown pattern. There are no raw field data to review for this period.

The record from July 26, 2000 to November 18, 2009 is rated good based on 23 water level measurements used to verify the recorded data.

The record from November 18, 2009 to November 15, 2010 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 11/16/2010 to 10/27/2011 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 10/27/2011 to 08/15/2012 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 08/16/2012 to 11/04/2013 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 11/04/2013 to 11/24/2014 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 11/25/2014 to 05/02/2016 is good based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 5/3/2016 to 11/28/2016 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 11/29/2016 to 08/08/2017 is fair  based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft., with the exception of the period from 02/16/2017 to 05/23/2017 which is rated poor. The period from 02/16/2017 to 05/23/2017 is rated poor due to frequent and sustained data gaps during the period. The record from 08/09/2017 to 01/22/2018 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 01/23/2018 to 07/02/2018 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 07/03/2018 to 08/14/2018 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 08/15/2018 to 03/25/2019 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 03/26/2019 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.
