LOCATION - Lat 37°39'55.2", long 91°06'59.4" referenced to North American Datum of 1983, in SW 1/4 SW 1/4 SW 1/4 sec.01, T.34 N., R.2 W., Iron County, MO, Hydrologic Unit 07140102,

REVISIONS HISTORY -
Revisions: Land-surface datum was updated to 1,387.14 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 1,380 ft NAVD88 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.

Previously Approved data from 10/01/1988 to 09/30/2009 was revised on 07/22/2010 and a measuring point height correction of -0.5 ft was applied to this period to reference water levels to land surface instead of the measuring point.

COOPERATION - Data furnished by Missouri Department of Natural Resources (MDNR); Record from October 1, 1988 to present furnished from MDNR. Record from Feb 2, 2000 to present processed by USGS and MDNR.

REMARKS -

Furnished record rated fair (October 1, 1988 to February 2, 2002)because no water level measurements are available to verify daily values. This data has been archived by Missouri Department of Natural Resources (MDNR) and is not available for verification. Data from February 2, 2002 to December 11, 2009 fair because 47 water level measurements were made during this period to verify recorded water levels. Record from 10/01/2007 to 09/30/2008 is considered good, except for period 12/12/2007 to April 2, 2008 which is considered fair. Record from 10/01/2008 to 09/30/2009 is considered good. Record from 10/01/2009 to 08/09/2010 is fair based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.3 ft. The float has a tendency to stick in the well. Periods where the float is stuck for several days have been removed. The record from 08/10/2010 to 11/09/2010 is fair based on the hydrograph appearance and 3 water level measurements made during the period and is accurate to +/- 0.3 ft. The float had a tendency to stick during this period causing the float to 'jump' +/- 0.3 ft at times. A lighter counterweight was installed at the gage on 11/09/2010 which seems to have considerably helped the problem. Although at times the float does still appear to be sticky, but the 'jumps' are under 0.1 ft. The record from 11/09/2010 to 09/01/2011 is good based on 7 water level measurements made during the period to verify the record and is accurate to +/- 0.1 ft. The record from 09/01/2011 to 09/30/2012 is good based on 3 water level measurements made during the period to verify the record and is accurate to +/- 0.05 ft. The record from 10/01/2012 to 09/15/2013 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 09/16/2013 to 12/18/2014 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 12/19/2014 to 06/08/2016 is good based on 5 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. The record from 06/09/2016 to 03/01/2017 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 03/02/2017 to 11/14/2017 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 11/15/2017 to 02/14/2018 is good based on 1 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 02/15/2018 to 05/02/2018 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 05/03/2018 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 +/- 0.10 ft. The record from 12/26/2018 to 04/10/2019 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 record from 04/11/2019 to 06/03/2019 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 record from 06/04/2019 to 01/07/2020 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.15 ft.
