Ohio River Low Flow – 7 Oct 2023 – Cairo Gauge

The Ohio River at Cairo is at 6.75 feet and falling at 10am CT. Discharges between McAlpine and Myers are less than 10kcfs with pools in the low to middle portion of their operating band. This has resulted in a forecast Cairo stage that will be below the optimal navigation stage 6.5 feet this afternoon and will be near 5 feet by tomorrow morning. These low stages are expected to persist for at least 72 hours. Flows at Kentucky and Barkley are steady at both projects as of this morning in response to this situation. Nevertheless, caution is advised for interests sensitive to low water stages along the lower Ohio and Mississippi Rivers. The next date for consideration of peaking at Kentucky and Barkley will be Wednesday 11 October 2023.

Rainfall is possible in the basin during the middle of next week, but we don’t anticipate any large scale relief from the low flows before that event.

Flows will continue to vary on a daily basis due to fluctuations that traverse the river. Active coordination is ongoing through the weekend and will continue into next week.
