Releases from Gavins Point Dam at Yankton continue at 40-thousand cubic feet per second, well above the long term normal for this time of year.

Jody Farhat, head of the Corps' water control office in Omaha, says levees and dams along the waterway were weakened by the months of flooding and repairs on them are still underway.

She says they're working to plan ahead by dropping reservoir water levels now.

Farhat says the Corps will continue with "aggressive" flows from the dams for the next few months.
