USGS Water-Year Summary 2023
373559090082901 National Lead
Ozark Plateaus aquifer system
Cambrian System
LOCATION - Lat 37°35'57.4", long 90°08'30.4" referenced to North American Datum of 1983, in NW 1/4 SE 1/4 SW 1/4 sec.34, T.34 N., R.8 E., Perry County, MO, Hydrologic Unit 07140107,
REVISIONS HISTORY - Revisions: Land-surface datum was updated to 984.52 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 992 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 984.52 ft above North American Vertical Datum of 1988. Measuring point: unknown, 1.4 ft above land-surface datum, Nov. 26, 1980 to present.  
PERIOD OF RECORD - July 22, 1960 to present.
GAGE - Stevens model A-35 chart recorder installed July 18, 1960. Stevens model 7001 digital recorder installed September 29, 1988. June 9, 2000 to present; DCP with float, encoder, and telemetry capability installed as the water level recording and measuring devices.
COOPERATION - Data furnished by Missouri Department of Natural Resources (MDNR); Record from July 18, 1960 to June 9, 2000 furnished from MDNR. Record from June 10, 2000 to present, processed by USGS and MDNR.
REMARKS - Furnished record rated good (November 26, 1980 to October 21, 1991) based on 45 water level measurements which are available for verification. The water level measurement is typically within +/-0.5 ft of the daily value measurement. This data has been archived by Missouri Department of Natural Resources (MDNR) and has been verified by USGS. Furnished record rated fair (July 18, 1960 to November 25, 1980 & October 22, 1991 to June 7, 2000) 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 This data has been archived by Missouri Department of Natural Resources (MDNR) and is not available. Data from November 26, 1980 to October 21, 1991 is rated good. Data from 06/08/2000 to 09/30/2008 has been processed by the USGS with 25 field water level measurements made during the period to verify the recorded water levels. This record is considered good. Data from 10/01/2008 to 04/20/2010 is good based on 6 water level measurements made during the period to verify the recorded water levels and is accurate to +/- 0.1 ft. The record from 04/20/2010 to 06/29/2010 is good based on 3 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.05 ft. However, 2 of these measurements were made at a gage start-up after the gage was inoperable. This record from 06/30/2010 to 05/10/2011 is good based on 6 water levels made during the period to verify the recorded data is accurate to +/- 0.05 ft. However, 4 of these measurments were made at a start-up after the gage was inoperable. This record from 05/10/2011 to 07/25/2012 is good based on 4 water levels made during the period to verify the recorded data is accurate to +/- 0.05 ft. The record from 07/26/2012 to 10/01 2012 is poor based on only 1 ending water level that was off by 0.36 ft. Not sure if this water level is good and with no measurements in between the last one and this it is hard to determine how good the data is. The record from 10/02/2012 to 08/05/2013 is good based on 3 water level measurements made during the period and is accurate to +/- 0.05 ft. The record from 08/06/2013 to 01/26/2015 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 01/27/2015 to 03/14/2016 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 03/15/2016 to 09/06/2016 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 record from 09/07/2016 to 06/20/2017 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 06/21/2017 to 12/18/2017 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 12/19/2017 to 08/01/2018 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 08/02/2018 to 05/20/2019 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 05/21/2019 to 11/04/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft.
