GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 495 ft. Upper casing diameter 10 in; top of first opening 152 ft, bottom of last opening 495 ft.
DATUM - Land-surface datum is 874.71 ft above North American Vertical Datum of 1988. Measuring point: unknown, 1.0 ft above land-surface datum, Dec. 29, 2011 to present.  
PERIOD OF RECORD - December 29, 2011 to present.
GAGE - December 29, 2012 to present; DCP with telemetry capability as the water level recording device. December 29, 2012 to August 11, 2015; Float driven encoder as the water level measuring device. August 11, 2015 to present; Pressure transducer as the water level measuring device.
COOPERATION - Record from December 29, 2011 to present, furnished from MDNR. Records processed by USGS and MDNR.
REMARKS -

The record from 12/29/2011 to 09/10/2012 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 09/10/2012 to 08/18/2013 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 float tends to stick and it appears that when a measurement is made it breaks loose. This may account for some water level measurements being off by 0.10 ft. Need to read the Encoder before and after measurement to see if any difference. The record from 08/19/2013 to 02/03/2015 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 02/04/2015 to 06/08/2016 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 06/09/2016 to 02/28/2017 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 03/01/2017 to 12/18/2017 is good based on 1 water level measurements made during the period to verify the recorded data and is accurate to +/-0.10 ft. The record from 12/19/2017 to 06/19/2018 is good based on 1 water level measurements made during the period to verify the recorded data and is accurate to +/-0.10 ft. The record from 06/20/2018 to 12/11/2018 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 12/12/2018 to 04/23/2019 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 04/24/2019 to 01/01/2020 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft.

All later correction notes and remarks can be found in RMS as of 01/02/2020.
