OMAHA, Neb. (AP) — The continued threat of rain and higher-than-normal reservoir releases into the Missouri River will hamper the draining of floodwaters in fields and plans to repair more than 100 levee breaks after devastating spring floods. Officials with the U.S. Army Corps of Engineers and the National Weather Service said Thursday that rain over the next week could lead to some parts of the lower end of the river rising as much as 2 feet.

SIOUX FALLS, S.D. (AP) — Officials say viewing platforms and walkways with railings are being installed at a Sioux Falls park where a 5-year-old girl drowned. The Argus Leader reports that city leaders set aside $300,000 last year to cover the cost of construction at Falls Park. A consultant recommended the safety measures after an Iowa girl fell into the Big Sioux River and drowned last year. Sioux Falls Mayor Paul TenHaken says the development should allow visitors of all ages and mobility to enjoy the park.

OMAHA, Neb. (AP) — Bankers surveyed in parts of 10 Plains and Western states are seeing improvement in the region’s farm economy.
