USGS Water-Year Summary 2023

370624092244701 Norwood Well

Ozark Plateaus aquifer system
Canadian Series

LOCATION - Lat 37°06'23.8", long 92°24'47.4" referenced to North American Datum of 1983, in SE 1/4 SE 1/4 SE 1/4 sec.13, T.28 N., R.14 W., Wright County, MO, Hydrologic Unit 11010006,

REVISIONS HISTORY -
Revisions: Land-surface datum was updated to 1,520.52 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 1,523 ft NAVD88 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.

On August 23, 2010 the record from May 3, 2005 to September 30, 2008 was set back from 'Approved' to 'In Review' by M Kleeschulte and a -1.7 ft measuring point height correction was applied to the entire period of record. This was done to reference the water levels to land surface instead of the measuring point.

REMARKS -

Data from 05/03/2005 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.The record from 05/03/2005 to 12/31/2005 is considered poor and accurate to +/-0.5 ft. Equipment problems during this period affected the accuracy of the record.The record from 01/01/2006 to 09/30/2008 is considered fair and accurate to 0.3 ft which appears to be the accuracy of the pressure transducer.Data from 10/01/2008 to 12/16/2009 has been processed by the USGS with limited field water level measurements (3 measurements) during the period to verify the recorded water levels. The record is considered good based on these 3 water level measurements and is accurate to +/- 0.2 ft.The record from 12/17/2009 to 05/11/2010 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.2 ft.The record from 05/11/2010 to 08/24/2011 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 transducer has an instrument drift that ranges from +/- 0.5 ft.The record from 08/24/2011 to 06/19/2012 is fair based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.5 ft. The transducer has an instrument drift that ranges from +/- 0.5 ft.The record from 06/20/2012 to 10/27/2013 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.5 ft. The transducer drifts +/- 0.5 ft.The record from 10/28/2013 to 09/16/2014 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.50 ft. The transducer has an instrument drift that ranges from +/- 0.50 ft.The record from 09/17/2014 to 10/31/2016 is poor based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 1.00 ft. This transducer is an instrument that is subject to significant drift. In this period of the record it has been found to drift over 10 ft. between measurements. The pressure transducer was replaced on 11/01/2016.The record from 11/01/2016 to 03/20/2017 is poor based on 1 water level measurement made during the period. The pressure transducer was removed on 11/02/2016 and was not replaced until 03/15/2017. During this time no water levels were recorded. The record from 03/21/2017 to 10/11/2017 is good based on 1 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.50 ft. The record from 10/12/2017 to 07/02/2018 is poor based on 1 water level measurement made during the period. The pressure transducer stopped transmitting on 04/13/2018, was removed on 04/25/2018, and was not replaced until 07/03/2018. During this time no water levels were recorded. The record from 07/03/2018 to 12/27/2018 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.2 ft. The transducer has an instrument drift that ranges from +/- 0.5 ft. The record from 12/28/2018 to 05/06/2019 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 fair rating is due to the gap of missing data and a lack of comparable water level measurement. The record from 05/07/2019 to 07/01/2019 is poor based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The poor rating is due to the gap of missing data and a lack of comparable water level measurement. The record from 05/07/2019 to 11/13/2019 is fair based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.50 ft. The fair rating is due to the gap of missing data and a lack of one comparable water level measurement.
