Alluvial aquifers
Holocene Alluvium

LOCATION - Lat 39°09'45", long 94°23'40.8" referenced to North American Datum of 1983, in SE 1/4 NE 1/4 SW 1/4 sec.12, T.50 N., R.32 W., Jackson County, MO, Hydrologic Unit 10300101,

REVISIONS HISTORY -
The data from 03/18/2008 to 10/04/2009 was revised after it was previously set to 'Approved' status. A -2.7 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.

Revisions: Land-surface datum was updated to 732.65 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 734 ft NGVD29 from a topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.
