Note: The USGS began operating this
streamgage in March 1933. Although USGS serves data prior to 1933 as a
courtesy to the water community, methods used to measure discharge and
compute daily discharge values before USGS operation are not fully
known and may be inconsistent with established USGS methods. Daily
discharge values for dates before March 1933 should be used recognizing
this added uncertainty.
Station operated in cooperation with the U.S. Army
Corps of Engineers - St. Louis District.
