LOCATION - Lat 37°28'52.8", long 91°06'20.3" referenced to North American Datum of 1983, in NW 1/4 SE 1/4 NE 1/4 sec.12, T.32 N., R.2 W., Reynolds County, MO, Hydrologic Unit 11010007, approximately 1.0 mile north of Fletcher Mine.

REVISIONS HISTORY -
Revisions: Land-surface datum was revised to 1,168.32 ft NAVD88 on Oct. 4, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published in error as 1,150 ft NGVD29 from topographic map. Discrete water-level measurements referenced to NGVD29 and NAVD88 were revised, based on changes to the land-surface datum.

A +0.07 ft correction was applied to the period 03/31/2008 to 04/02/2008 after it was previously approved. A correction was applied incorrectly in ADAPS and needed to be corrected.
