384917091594401 Fulton

Cambrian-Ordovician aquifer system
Canadian Series

LOCATION - Lat 38°49'16.0", long 91°59'44.0" referenced to North American Datum of 1983, in NE 1/4 NE 1/4 SW 1/4 sec.25, T.47 N., R.10 W., Callaway County, MO, Hydrologic Unit 10300102,

REVISIONS HISTORY - Revisions: Land-surface datum was revised to 878.94 ft NAVD88 on Oct. 4, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published in error as 865 ft NAVD88 from topographic map. Discrete water-level measurements referenced to NGVD29 and NAVD88 were revised, based on changes to the land-surface datum.

GROUNDWATER RECORDS

DATUM - Land-surface datum is 878.94 ft above North American Vertical Datum of 1988. Measuring point: unknown, 2.5 ft above land-surface datum, Jan. 28, 2010 to present.  

GAGE - From February 03, 2010 to present, the water level recording device is a DCP with telemetry capability setting in a metal box on top of casing. From February 03, 2010 to present, the water level measuring device is a float driven encoder.

COOPERATION - From February 03, 2010 to present, the water level data is furnished by the Missouri Department of Natural Resources (MDNR). From February 03, 2010 to present, the water level record is processed by USGS and MDNR.

REMARKS - The float has a tendency to stick in this well for short periods of time (usually less than 12 hours). Data 'jumps' when the float becomes free are typically less than 0.1 ft. The record from 02/03/2010 to 07/17/2010 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.1 ft. The record from 07/18/2010 to 10/18/2011 is good based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.1 ft. The record from 10/19/2011 to 08/13/2012 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 08/14/2012 to 09/24/2013 is fair based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.20 ft. The float would regularly become stuck throughout the period and then jump when free. Jumps were usually less than 0.20 ft. The record from 09/25/2013 to 01/14/2015 is fair based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.20 ft. Float sticking in well quite often. The record from 01/15/2015 to 07/05/2015 is fair based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.20 ft. Float sticking in well quite often. The record from 07/06/2015 to 11/13/2016 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 11/14/2016 to 04/24/2018 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 04/25/2018 to 05/22/2018 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 05/23/2018 to 07/23/2018 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 07/24/2018 to 02/25/2019 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 02/26/2019 to 03/31/2019 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 04/01/2019 to 09/04/2019 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 later correction notes and remarks can be found in RMS as of 09/05/2019.

PERIOD OF DAILY RECORD - From February 03, 2010 to present.
