(OMAHA, Neb., AP) — The amount of water flowing into the lower Missouri River will be increased this week because of concerns about colder temperatures, but the increase isn’t likely to boost the level of the Mississippi River downstream.

The U.S. Army Corps of Engineers says it plans to gradually increase the amount of water it releases out of Gavins Point dam on the South Dakota-Nebraska border to 18,000 cubic feet per second by Thursday.

That’s an increase of 4,000 cubic feet per second over current levels.

The corps’ Jody Farhat says the change is needed because ice will begin forming on the river with the cold weather and reduce the flow. The additional water will make sure the river remains high enough for cities that rely on its water.
