MACY, Neb. (AP) – The White House says the Obama administration has raised the federal share of public aid for the Omaha Tribe’s recovery from the 2011 Missouri River flooding. A news release sent Wednesday says the level has been raised to 90 percent of the total eligible costs from 75 percent. It’s unclear why the aid was increased.

Hundreds of thousands of acres of land were flooded along the Missouri River in Iowa, Nebraska and Missouri in 2011 after heavy spring rains and a giant mountain snowpack forced massive releases from upstream dams. The Omaha Indian Reservation lies primarily in northeast Nebraska but extends across the Missouri River into Monona County, Iowa.
