NEVADA, Iowa (AP) — A former Iowa State University student is expected to be sentenced Thursday for sexually assaulting an unconscious female student after a party. A plea agreement calls for 21-year-old Patrick Whetstone to avoid prison but be required to register as a sex offender for 10 years. The case has roiled Iowa State and led to a federal investigation of the school.

AMES, Iowa (AP) — An Iowa State University airplane was out of state far longer than the school has acknowledged after it was damaged by President Steven Leath last year. A record obtained by The Associated Press shows the plane didn’t fly back to Iowa until 10 weeks after Leath’s rough landing at the Bloomington, Illinois airport. A university spokesman said this week the plane was stored in Illinois for three to four weeks after the July 14, 2015 incident. But the record shows it didn’t return to Iowa until Sept. 23, when it was flown to Pella for repairs. The school says repairs and storage cost $13,691. Leath made a $15,000 donation to cover those costs and vowed to stop flying university aircraft. The accident came as Leath returned from an 11-day vacation.

CEDAR RAPIDS, Iowa (AP) — An elaborate system of temporary floodwalls is so far protecting thousands of homes and businesses in Cedar Rapids from major flooding. Iowa’s second-largest city says its hastily erected 9.8-mile system of barriers and earthen berms is largely holding back the Cedar River. The river crested Tuesday at its second-highest level on record. It’s expected to be back below flood stage Sunday.

CEDAR RAPIDS, Iowa (AP) — Authorities say the Cedar River is slowly receding from its crest in Cedar Rapids, Iowa, and a new forecast says the water level will drop below flood stage sooner than expected. A city spokeswoman says the city’s temporary flood protection system is holding the water at bay Wednesday. The swollen river is expected to be back under flood stage Sunday, a day earlier than previously forecast.

CEDAR RAPIDS, Iowa (AP) — Miles of hastily erected barriers were remarkably effective in preventing the surging Cedar River from pouring into Cedar Rapids, Iowa’s second-largest city, but officials said the sand-filled containers wouldn’t work in every flooding situation. Officials warned the city may not always have enough time to build a makeshift wall, which took around-the-clock work. Cedar Rapids leaders still support construction of a $500 million system of flood barriers.
