GROUNDWATER RECORDS

DATUM - Land-surface datum is 919.46 ft above North American Vertical Datum of 1988. Measuring point: unknown, 2.4 ft above land-surface datum, Sep. 23, 2009 to present.  

PERIOD OF RECORD - September 23, 2009 to present.

GAGE - From September 23, 2009 to present, DCP with telemetry capability is water level recording device and float and encoder is the water level measuring device.

COOPERATION - From September 23, 2009 to present, data furnished by the Missouri Department of Natural Resources (MDNR) and data processed by the USGS and MDNR.

REMARKS - The record from 09/23/2009 to 11/18/2010 is good based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 11/18/2010 to 08/30/2011 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 08/30/2011 to 08/14/2012 is good based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 08/15/2012 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 +/- 0.03 ft. The record from 11/05/2013 to 12/15/2014 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 12/16/2014 to 06/29/2016 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 06/30/2016 to 03/14/2017 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 float occasionally gets stuck and then breaks loose resulting in jumps typically less than 0.10 ft that bring the hydrograph back into alignment. The record from 03/15/2017 to 04/16/2018 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 04/17/2018 to 12/25/2018 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 12/26/2019 to 04/16/2019 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 04/17/2019 to 09/16/2019 is poor based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.30 ft. The poor rating is a result of extensive missing days during this time period, beginning on 04/23/2019 and ending well after the last site visit on 11/19/2019.
