Low Water Event of Summer, 2005

A prolonged period of below normal rainfall that began after the January, 2005 flooding brought river elevations to some of their lowest levels in recent years. Both the Mississippi and Lower Ohio Rivers were low enough to affect river transportation.

  • River transportation was negatively impacted. During early and mid August, there were intermittent closures of the lower Ohio River  (near Cairo, IL) to most barge traffic. Interrupted deliveries of fuel and other commodities were common.
  • Emergency dredging operations improved channel depth on both the Ohio and Mississippi Rivers, and helped limit the duration of the closure.
  • Below is a graphic presentation of the Ohio River level at Cairo, IL from July 15 to August 12. Flood stage at Cairo is 40 feet. 
  • The level dipped to about 7 feet on August 9.
