Daily mean discharge graphs for 3 U.S. Geological Survey streamflow-gaging stations
in the northern, central, and southern parts of the State of Illinois are presented here. The
graphs represent 1 year of data from today's date.
Graphs are updated daily.
Daily mean discharge for the 1-year time period is compared with the percentile distribution of mean
daily discharges for the 30-year period, 1961-90. Daily mean discharge is in the deficient-flow
range if its value is less than or equal to the 25th percentile, in the normal-flow range
if its value is between 25th and 75th percentiles, and in the excessive-flow range if its value
is equal to or greater than the 75th percentile.
