ice.
Station operated in cooperation with the U.S. Army Corps of Engineers—St. Louis District
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.
