Water-Year Summary for Site 385845090583801
Furnished record rated good (December 19, 1980 to August 28, 1991) because 47 water level measurements are available and are within 0.5 ft of the daily value measurement. This data has been archived by Missouri Department of Natural Resources (MDNR) and has been verified by USGS.
Furnished record rated fair (August 29, 1991 to September 21, 2000)because no water level measurements are available to verify daily values. This data has been archived by Missouri Department of Natural Resources (MDNR) and is not available for verification.
Data from 09/22/2000 to 09/30/2008 has been processed by the USGS with limited field water level measurements (13 measurements) during the period to verify the recorded water levels. This record is considered fair.
Data from 10/01/2008 to 11/18/2009 is fair based on 5 water level measurements made during the period to verify the record and is accurate to +/- 0.3 ft. The pressure transducer has problems keeping it's calibration and frequent instrument drift is occurring.
Data from 11/19/2009 to 07/26/2010 is fair based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.5 ft.
Data from 07/27/2010 to 08/31/2011 is fair based on 7 water level measurements made during the period to verify the recorded data. The record from 07/27/2010 to 10/27/2010 and 05/31/2011 to 08/31/2011 is accurate to +/- 0.5 ft. the record from 10/27/2010 to 05/31/2011 is accurate to +/- 1.0 ft.
Data from 08/31/2011 to 08/07/2012 is fair based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.5 ft. The reason for this is the potential for drift of the pressure transducer.
Data from 07/28/2012 to 08/08/2012 is accurate to +/- 2.0 ft due to the water level dropping under the pressure transducer for several days. The record from 08/08/2012 to 07/02/2013 is fair based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 2.00 ft. Pressure transducer is really drifting from visit to visit.
The record from 07/03/2013 to 01/20/2015 is good based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10.ft. New Pressure transducer installed 07/08/2014.
The record from 01/21/2015 to 07/12/2016 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 07/13/2016 to 11/15/2016 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 11/16/2016 to 07/26/2017 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 07/27/2017 to 01/30/2018 is good based on 1 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft.
The record from 01/31/2018 to 08/21/2018 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 08/22/2018 to 02/26/2019 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 02/27/2019 to 09/10/2019 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 09/11/2019.
