Hydrologic History
The United States Geological Survey maintains four monitoring stations, in cooperation with National Weather Service, along the Kishwaukee River and has extensive data on low records and high crests and other information that is hydrologically pertinent. The four stations are in DeKalb, Fairdale, Belvidere and Perryville Road in Rockford. The DeKalb and Fairdale stations are along the South Branch Kishwaukee while the other two are both along the main branch. Flood stages vary slightly at each of the monitoring stations. At DeKalb flood stage is 10 feet (3 m) with moderate flood stage at 11 and major set at 12.5 feet (3.8 m). In Belvidere major flood stage is at 12 feet (4 m), while moderate is at 10 and flood stage is at nine feet. In Perryville, near the mouth of the Kishwaukee, flood stage is 12 feet (4 m), moderate flood stage is 18 and major flood stage is 22 feet (7 m).

Famous quotes containing the word history:
“No one is ahead of his time, it is only that the particular variety of creating his time is the one that his contemporaries who are also creating their own time refuse to accept.... For a very long time everybody refuses and then almost without a pause almost everybody accepts. In the history of the refused in the arts and literature the rapidity of the change is always startling.”
—Gertrude Stein (1874–1946)
