Our transcription: A detailed study of Red Eye Crossing is currently underway at the Army Corps' Waterways Experiment Station or "WES" in Vicksburg, Mississippi.
Tom Pokrefke is chief of the River engineering branch and heads the Red Eye investigation.
The problem that we're studying on Red Eye Crossing is the Crossing itself, when you go from a low water situation to a high water situation, tends to fill with sediment.
Where you go from high water to low water, there's just not enough energy in the water to clear that Crossing out and maintain the channel deep enough for ship-type navigation in that part of the River.
Basically, the Red Eye Crossing area's been kept open in the past using dredging.
When the channel fills during going from a low water situation to a high water situation, the Corps of Engineers went out and dredged the channel, to make sure it was deep enough.
