USGS Water-Year Summary 2023

385512088112401 6N9E-34.1h (Jasper CRN)

Sand and gravel aquifers (glaciated regions)
Quaternary System

LOCATION - Lat 38°55'11.90", long 88°11'24.00" referenced to North American Datum of 1983, in NE 1/4 NE 1/4 NE 1/4 sec.34, T.6 N., R.9 E., Jasper County, IL, Hydrologic Unit 05120112,

REVISIONS HISTORY -
Revisions: Land-surface datum was revised to 584.25 ft NAVD88 on Nov. 21, 2023, as determined by a GNSS Level II survey. Land-surface datum was previously published as 582.00 ft NAVD88 from topographic map. Discrete water-level measurements referenced to NGVD29 and NAVD88 were revised, based on changes to the land-surface datum.
Revisions: Water levels below land-surface datum prior to July 11, 2023, and associated discrete water-level measurements prior to Oct. 10, 2023, were revised on Nov. 21, 2023, due to an incorrect measuring point (MP) height. Previous MP was 0.85 ft above land-surface datum (LSD). New corrected MP height is 0.67 ft above LSD.
