05553500       ILLINOIS RIVER AT OTTAWA, IL

 

LOCATION.-- Lat 41°20'17", long 88°51'10" (NAD of 1927), in SW1/4SW1/4 sec.11, T.33 N., R.3 E., LaSalle County, Hydrologic Unit 07130001, downstream of the railroad bridge, 0.25 miles, and downstream 0.5 miles of the Route 23 bridge in Ottawa and the confluence with the Fox River.

 

DRAINAGE AREA.-- 10,949 mi2.

 

PERIOD OF RECORD.--

SURFACE-WATER DISCHARGE AND STAGE

 

DISCHARGE: March 11, 1903 to December 31, 1903.

 

PARTIAL RECORD: Miscellaneous discharge measurements, water years 1903-1904.

SURFACE-WATER QUALITY

 

CHEMICAL: Water years 1997 to 2004.

 

MISCELLANEOUS: Contaminants in streambed sediments, August 1998; contaminants in fish tissue, August, 1998.

BIOLOGICAL

 

ALGAE: Water years 1997-99 and 2002-04.

 

BENTHIC MACROINVERTEBRATES: Water years 1998-99, 2002-04.

 

FISH: Water years 1998-99, 2002-04.

 

HABITAT: Water years 1998-2000, 2003.

 

GAGE.-- Prior to November 1, 1903, vertical staff at west end of first pier from the north abutment of the railroad bridge at same datum. November 1, 1903 to February 21, 1904, chain gage read twice daily. Datum of gage is 579.48 ft above NGVD of 1929 (579.30 ft NAVD 1988).

 

REMARKS.-- Discharges for surface-water quality data for water years 1997 to current are computed by adding discharges of Illinois River at Marseilles (05543500) and Fox River at Dayton, IL (05552500).

 

EXTREMES FOR PERIOD OF RECORD.--

SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 46,900 ft3/s, Apr. 15, 1903, gage height, -119.08 ft (460.40 ft above NGVD of 1929); minimum discharge, 6,740 ft3/s, Sept. 8, 1903.

 

REMARKS FOR CURRENT YEAR.--Algae community samples were collected as part of the National Water-Quality Assessment program (NAWQA) in the lower Illinois River Basin. A quantitative sample was collected in accordance with NAWQA protocols (Cuffney and others, 1993). The quantitative phytoplankton sample was taken by collecting a representative whole-water sample of sufficient volume to ensure adequate phytoplankton biomass for analysis. All samples were processed by the Philadelphia Academy of Natural Sciences. Reach A begins at the red buoy near river mile 239, marking the top of Hitt Island, and continues downstream for 3281 ft, which is 492 ft downstream of the Ottawa navigation light number 238.5.
