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 36°11'45.2", long 89°39'40.7" referenced to North American Datum of 1983, in NW 1/4 SW 1/4 sec.16, T.18 N., R.13 E., Pemiscot County, MO, Hydrologic Unit 08020204,
REVISIONS HISTORY -
Revisions: Land-surface datum was updated to 270.38 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 270 ft NAVD88 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.
On January 3, 2012, the period from August 29, 2007 to December 9, 2009 was set to 'Working' status after it had previously been set to 'Approved' status. A -1.2 ft measuring point height correction was applied to the period to reference the water levels to land surface instead of the measuring point to which it was previously referenced.
