Canadian Series

LOCATION - Lat 37°10'35.5", long 94°17'13.3" referenced to North American Datum of 1983, in SE 1/4 SW 1/4 NW 1/4 sec.02, T.28 N., R.31 W., Jasper County, MO, Hydrologic Unit 11070207,

REVISIONS HISTORY -

The record from 06/28/2005 to 05/02/2006 was modified by -0.13 ft after it was set to Approved status. A prorated correction from zero to -0.25 ft was applied to the record from 02/21/2007 to 10/02/2007 after it was set to Approved status.

Revisions: Land-surface datum was updated to 963.54 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 963 ft NGVD29 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.

GROUNDWATER RECORDS

DATUM - Land-surface datum is 963.54 ft above North American Vertical Datum of 1988. Measuring point: unknown, 1.2 ft above land-surface datum, Aug. 1, 1960 to present.  

PERIOD OF RECORD - November 5, 2003 to present.

REMARKS - Data from 11/05/2003 to 09/30/2008 has been processed by the USGS with limited field water level measurements (6 measurements) during the period to verify the recorded water levels. This record is good and accurate to +/- 0.2 ft except for periods when the float was stuck. These periods have been removed. Data from 10/01/2008 to 04/14/2010 is good based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.2 ft. Data from 04/15/2010 to 08/17/2010 is good based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 08/17/2010 to 05/23/2011 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.1 ft. Data from 05/23/2011 to 10/13/2011 is fair based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.5 ft. Data from 10/13/2011 to 07/24/2012 is good based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.1 ft. Data from 07/25/2012 to 10/09/2013 is good based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.1 ft. The data from 10/10/2013 to 12/08/2014 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 data from 12/09/2014 to 05/23/2016 is fair based on 6 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.50 ft. The data from 05/24/2016 to 03/08/2017 is poor based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 1.50 ft. Both of these measurements were made after working on the well to get the float unstuck and then re-calibrated. Since no measurements were taken while the float was operating properly, there is no way to determine the degree of accuracy for the data recorded during this period. The data from 03/09/2017 to 10/25/2017 is poor based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 1.50 ft. This measurement was made after working on the well to get the float unstuck and then re-calibrated. Since no measurements were taken while the float was operating properly, there is no way to determine the degree of accuracy for the data recorded during this period. The data from 10/26/2017 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 +/- 0.10 ft. The data from 01/31/2018 to 07/11/2018 is fair based on 1 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.50 ft. The data from 07/12/2018 to 01/08/2019 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 data from 01/09/2019 to 06/26/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.50 ft. The data from 06/27/2019 to 01/13/2020 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.10 ft.
