USGS Water-Year Summary 2024

05528100 DES PLAINES RIVER AT LINCOLNSHIRE, IL

LOCATION - Lat 42°12'02", long 87°55'07" referenced to North American Datum of 1983, in NW 1/4 SE 1/4 SW 1/4 sec.14, T.43 N., R.11 E., Lake County, IL, Hydrologic Unit 07120004, on right upstream side of the Illinois Route 22 (Half Day Road) bridge, and at mile 80.

DRAINAGE AREA - 273 mi².

REVISIONS HISTORY -

WRD IL-75-1: Drainage area.
Revisions: Gage datum was updated to 630.06 ft NAVD88 on May 30, 2023, based on a GNSS Level II survey using GEOID18.

The period of Dec. 20, 2022 to Feb. 7, 2023 was revised. Stage data was originally deleted from Dec. 23 - Jan. 2 and Jan. 31 to Feb. 4 during a period of ice. The stage data during that period was real and should have been left in the record. The discharge estimated form Dec. 23 to Jan. 2 was updated to estimate every 720 min.

The total discharge computed during Qm 96 (Mar. 2, 2023) was found to be in error by more than the assigned uncertainty (8%). The transducer depth was incorrectly input prior to the measurement, which overestimated the total measurement discharge. The total discharge was revised from 1,575 cfs to 1,440 cfs.
