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.

Eminence-Potosi Dolomites
LOCATION - Lat 36°37'28.3", long 93°15'06.1" referenced to North American Datum of 1983, in SW 1/4 NE 1/4 NW 1/4 sec.07, T.22 N., R.21 W., Taney County, MO, Hydrologic Unit 11010003,
REVISIONS HISTORY - Revisions: Land-surface datum was revised to 853.26 ft NAVD88 on Oct. 4, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published in error as 840 ft NAVD88 from topographic map. Discrete water-level measurements referenced to NGVD29 and NAVD88 were revised, based on changes to the land-surface datum.
GROUNDWATER RECORDS
DATUM - Land-surface datum is 853.26 ft above North American Vertical Datum of 1988. Measuring point: unknown, 1.0 ft above land-surface datum, Aug. 8, 2001 to present.
PERIOD OF RECORD - April 22, 1996 to present.
GAGE - Stevens model 7001 digital recorder installed April 22, 1996. August 15, 2001 to present, DCP with float, encoder, and telemetry capability was installed as the water level recording device.
COOPERATION - Data furnished by Missouri Department of Natural Resources (MDNR); Record from April 22, 1996 to February 15, 2001 furnished from MDNR. Record from February 15, 2001 to present processed by USGS and MDNR.
ECOLOGICAL RECORDS
REMARKS - Furnished record from April 22, 1996 to Februrary 15, 2001 is rated fair because no water level measurements are available to verify the data.
Data for the period Feb. 16, 2001 to Sept. 28, 2009 is considered good except for the period Feb. 16, 2001 to June 7, 2001 which is considered fair and the period Sept. 23, 2003 to May 13, 2004 which is considered poor based on 33 water level measurements made during this period to verify recorded water levels.
Data from 09/29/2009 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 +/- 0.1 ft, except for the period from 04/20/2010 to 04/26/2010 which is fair because of a float sticking problem and is accurate to +/- 0.3 ft.
The record from 08/18/2010 to 05/23/2011 is good based on 3 water level measurements made during the period and is accurate to +/- 0.05 ft. However, on occasions the float has a tendency to stick. typically when the float becomes free, the float jumps about 0.1 ft or less.
The record from 05/24/2011 to 10/02/2012 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 10/03/2012 to 10/01 2013 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 record from 10/02/2013 to 12/09/2014 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 12/10/2014 to 04/04/2016 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 04/05/2016 to 10/12/2016 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 10/13/2016 to 03/29/2017 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 03/30/2017 to 03/21/2018 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 03/22/2018 to 05/22/2018 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 05/23/2018 to 09/18/2018 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 09/19/2018 to 01/09/2019 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 01/10/2019 to 06/24/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft.
All further remarks can be found in RMS as of 9/3/2019.
