| 摘要： | The State of Illinois diverts water from Lake Michigan into the Chicago River system at three locations in the Chicago vicinity. A U. S. Supreme Court decree limits the diversion to an annual mean discharge of 3,200 cubic feet per second (ft3/s). An accurate computation of discharge and an assessment of the uncertainty in the discharge data are required for the Lake Michigan Diversion Project. As part of this project, the U.S. Geological Survey (USGS), in cooperation with the U.S. Army Corps of Engineers-Chicago District, computed discharge and analyzed the error to evaluate the uncertainty in the discharge computations for Water Years (WYs) 97-99.Daily mean discharges were computed at four acoustic velocity meter (AVM) streamflow-gaging stations on the Chicago River system for a 3-year period (1997-99 WYs). The four stations were:Chicago Sanitary and Ship Canal at Romeoville, Illinois (05536995); Chicago River at Columbus Drive at Chicago, Illinois (05536123); Calumet River below OBrien Lock and Dam at Chicago, Illinois (05536358); and North Shore Channel at Wilmette, Illinois (05536101). / NOTE:Scientific investions rept. |
