Officials are again planning to temporarily boost how much water flows into the Missouri River to test the concrete spillway on Gavin's Point Dam on the South Dakota-Nebraska border.
The U.S. Army Corps of Engineers had planned to conduct this latest test last week, but it rescheduled because of the rain and snow that fell in the region. The eight-hour test is now scheduled for Tuesday.
The amount of water flowing into the river will increase from the current 19,500 cubic feet per second to as much as 40,000 cubic feet per second. And the water will be shifted out of the dam's power generator to the spillway.
Following the test, the level of the Missouri River will rise temporarily downstream of Gavin's Point.
