LOCATION - Lat 36°35'54.5", long 90°15'37.4" referenced to North American Datum of 1983, in SE 1/4 SE 1/4 NW 1/4 sec.36, T.23 N., R.7 E., Butler County, MO, Hydrologic Unit 08020302,

REVISIONS HISTORY -
Revisions: Land-surface datum was updated to 315.19 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 315 ft NAVD88 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.

The record from 09/21/2000 to 12/08/2009 was modified after it was previously set to 'Approved' status. A -1.9 ft measuring point height correction was applied to this period to reference the water level data to land surface instead of the measuring point which is referenced in the field.
