USGS Water-Year Summary 2023

371558093181901 McDaniel Lake

Ozark Plateaus aquifer system
Canadian Series

LOCATION - Lat 37°17'55.9", long 93°18'20.3" referenced to North American Datum of 1983, in NE 1/4 SE 1/4 NW 1/4 sec.25, T.30 N., R.22 W., Greene County, MO, Hydrologic Unit 10290106,

REVISIONS HISTORY - The period from 08/11/2008 to 09/30/2008 was modified -0.05 ft after it was set to 'Approved'. Two consecutive gage resets that nullified each other were discovered and the original correction was removed.

GROUNDWATER RECORDS

DATUM - Land-surface datum is 1,138 ft above North American Vertical Datum of 1988. Measuring point: Undefined, 2.0 ft above land-surface datum, Jun. 13, 2001 to present. --Top of recorder shelf setting on top of casing; 2.0 ft above land surface.

PERIOD OF RECORD - January 11, 2002 to present.

GAGE - January 11, 2002 to present telemetry DCP. January 11, 2002 to 03/07/2007 and 06/23/2011 to 03/29/2016, water level measuring device was float driven encoder. From 03/07/2007 to 06/23/2011, and 03/29/2016 to present the water level measuring device is a vented, submersible pressure transducer.

COOPERATION - Data furnished by Missouri Department of Natural Resources (MDNR). Data processed by USGS and MDNR.

REMARKS - Data from 01/11/2002 to 09/30/2008 has been processed by the USGS with limited field water level measurements (11 measurements) during the period to verify the recorded water levels. This record is good and accurate to +/- 0.2 ft. Data from 10/01/2008 to 03/11/2009 is good and accurate to +/- 0.1 ft and the data from 03/11/2009 to 01/25/2010 is fair and accurate to +/- 1.0 ft based on 4 water level measurements made during the period. The accuracy of the data from 03/11/2009 to 01/25/2010 is affected by the transducer being submerged out of its pressure range. Data from 01/25/2010 to 08/18/2010 is fair based on 4 water level measurements made during the period to verify the recorded water level data. The data is accurate to +/- 1.0 ft. Data from 08/18/2010 to 06/23/2011 is poor based on 5 water level measurements made during the period to verify the recorded water level data. The data is accurate to +/- 1.0 ft. Data from 06/23/2011 to 05/17/2012 is good and accurate based on 4 water level measurements made during the period to verify the recorded water level data. The data is accurate to +/- 0.20 ft. Data from 05/17/2012 to 12/04/2012 is poor based on 2 water level measurements made during the period to verify the recorded water level data is accurate to +/- 1.00 ft. Data during this period indicated greater than usual instrument drift. This may have been due to a sticking float or slipping of the tape on the spline. Data from 12/05/2012 to 11/17/2013 is good and accurate based on 4 water level measurements made during the period to verify the recorded water level data is accurate to +/- 0.20 ft. The record from 11/18/2013 to 11/15/2014 is fair based on 2 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.20 ft. One WL made during this period was deemed bad and not used. The record from 11/16/2014 to 03/28/2016 is fair based on 7 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. One of the seven water level measurements made during this period was deemed to be bad and was not used. The record from 03/29/2016 to 09/27/2016 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 09/28/2016 to 04/04/2017 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft.
