Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

LOCATION - Lat 37°59'30.9", long 94°22'01.7" referenced to North American Datum of 1983, in NE 1/4 SE 1/4 NW 1/4 sec.17, T.37 N., R.31 W., Vernon County, MO, Hydrologic Unit 10290103,
GROUNDWATER RECORDS
GAGE - From March 31, 2010 to present, the water level recording device is a DCP with telemetry capability setting on top of recorder shelf on top of the casing. From March 31, 2010 to present, the water level measuring device is a vented, submersible pressure transducer.
COOPERATION - From March 31, 2010 to present, the water level data is furnished by the Missouri Department of Natural Resources (MDNR). From March 31, 2010 to present, the water level data is processed by the USGS and MDNR.
REMARKS - From 03/31/2010 to 07/13/2010, the transducer was fluctuating daily +/- 0.5 ft in a cyclical pattern every 5 to 6 hours. The pressure transducer was raised about 4 ft on 07/13/2010 to get it out of the screened interval of the well because of the accumulation of clay on the transducer. This modification caused the daily fluctuations in hydrograph to disappear, this gave the hydrograph a different appearance and better quality data. The record from 03/31/2010 to 07/13/2010 is poor based on the 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 1 ft. The data from 07/13/2010 to 09/21/2010 is good based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.2 ft.
The data from 09/21/2010 to 08/17/2010 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 data from 08/17/2011 to 09/05/2012 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 data from 09/06/2012 to 10/12/2013 is fair based on only 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft.
The record from 10/13/2013 to 12/08/2014 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 12/09/2014 to 12/15/2015 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.10 ft. Record from 12/15/2015 to 04/26/2016 is considered fair as no water levels were made and gage was taken out of service.
PERIOD OF DAILY RECORD - From March 31, 2010 to present.
