USGS Water-Year Summary 2023
361145089394101 Caruthersville
Mississippi embayment aquifer system
Wilcox Group
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.
