- 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.

Revisions: Land-surface datum was updated to 1,044.46 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 1,045 ft NAVD88 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.
The record from 04/19/2007 to 09/30/2008 has been modified after it was previously set to 'Approved' status. A -2.1 ft measuring point height correction has been applied to this data to reference the data to land surface instead of the measuring point which is referenced in the field.
A nearby pumping well caused rapid water level fluctuations of 7 to 9 ft to occur daily during the period 04/19/2007 to 03/17/2008. Data from 04/19/2007 to 09/30/2008 has been processed by the USGS with limited field water level measurements (2 measurement) during the period to verify the recorded water levels. The record from 04/19/2007 to 03/26/2008 is considered poor because no water level measurements were made during the period and a -0.54 ft correction was needed during the 03/26/2008 site visit which was about 11 months after the gage was started. Data from 03/26/2008 to 09/30/2008 is good (after the reset on 03/26/2008) based on the water level measurement made during the next site visit on 10/02/2008. Data from 10/01/2008 to 04/13/2010 is good based on the 5 water level measurements made during this period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 04/13/2010 to 08/10/2011 is good based on the 5 water level measurements made during this period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 08/10/2011 to 04/08/2012 is good based on the 5 water level measurements made during this period to verify the recorded data and is accurate to +/- 0.05 ft. Data from 04/09/2012 to 11/04/2013 is good based on the 5 water level measurements made during this period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 11/05/2013 to 11/24/2014 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 11/25/2014 to 05/17/2016 is good based on 4 water level measurements made during the period to verify the recorded data and is accurate to +/- 0.15 ft. The record from 05/18/2016 to 11/28/2016 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 11/29/2016 to 06/06/2017 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 06/06/2017 to 01/31/2018 is good based on 2 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 02/01/2018 to 07/02/2018 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 07/03/2018 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 +/- 0.10 ft. The record from 08/02/2018 to 03/25/2019 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 03/26/2019 to 05/14/2019 is good based on 1 water level measurement made during the period to verify the recorded data and is accurate to +/- 0.05 ft. The record from 05/15/2019 to 09/09/2019 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 later correction notes and remarks can be found in RMS as of 09/10/2019.
