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

The precipitation data for this station are temporary and will only be displayed for 120 days. Time series of cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once/year, the temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.

Current stage-discharge rating

  To determine water level in feet above sea level:
add current gage reading + 625.00 (NGVD 29 datum)
add current gage reading + 624.63 (NAVD 88 datum)
