GAGE.-- Acoustical flowmeter and phone telemeter. Datum of gage is 551.89 ft above sea level (U.S. Army Corps of Engineers bench mark).

REMARKS.-- Estimated daily discharges determined from a regression relation between present site and the previous site 5.2 mi downstream.

This gaging station provides flow data essential to determine Illinois' diversion of Lake Michigan water. A U.S. Supreme Court Decree limits Illinois' diversion to an average of 3,200 ft3/s. Illinois' diversion includes water diverted from the lake for domestic water supply, for navigation and water-quality improvement in the Chicago Sanitary and Ship Canal system, and the stormwater runoff from a 673 mi2 diverted watershed area. Flows recorded at this station also include nondiversion flows.

EXTREMES FOR PERIOD RECORD.--
SURFACE-WATER DISCHARGE AND STAGE: Maximum discharge, 19,466 ft3/s, Feb. 21, 1997, gage-height, 23.95 ft; maximum gage-height, 26.43 ft, Feb. 4, 1996; minimum discharge, no flow or periods of reverse flow at times in most years.

REMARKS FOR CURRENT YEAR.-- Sampled as part of the Upper Illinois River Basin (UIRB) National Water Quality Assessment Program (NAWQA).
