SIOUX CITY, Iowa (AP) – A free outdoor concert has been planned to thank the thousands of people who have volunteered to help fight Missouri River flooding in the Sioux City area. The concert is scheduled to begin at 8 p.m. Saturday at the Sioux City Center parking lot. Bush Hawg and Toby McBrooks will perform.

The Army Corps of Engineers is releasing massive amounts of water into the river from dams upstream. Those releases will keep the river above flood stage along Nebraska and Iowa at least into August.
