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. A Federal Emergency Management Agency spokesman said he couldn’t immediately reply. A tribal representative didn’t immediately return a message.

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.
