IOWA CITY, Iowa (AP) — University of Iowa experts advised Gov. Kim Reynolds last week not to relax social distancing rules, warning that the state could suffer a “catastrophic loss of life” even with them and see a second wave of infections. In a research paper made public Tuesday, the professors from the UI College of Public Health said they saw “considerable uncertainty” in how many deaths Iowa could get, ranging deaths from 150 to thousands even with strict social distancing rules. Days after receiving that warning, the Republican governor signed orders to partially reopen 77 of the state’s 99 largest counties and allow church services and farmers markets to resume statewide.

ARNOLD, Mo. (AP) — Some communities in the U.S. heartland are taking a more natural approach to preventing the kinds of floods that have devastated the region in recent years. For more than a century, flood control has relied mostly on man-made structures such as levees and walls to keep rivers in place. As climate change brings more extreme weather, the new idea is to let rivers behave more naturally. It means keeping some waterfront areas vacant or using them as parkland so no great harm is done when the rivers overflow. In rural areas, officials are considering moving levees farther back to give rivers more room to roam.

ROCKWELL CITY, Iowa (AP) — An Iowa sheriff has resigned after being charged with assaulting his wife and officers who arrested him. Calhoun County Sheriff Scott Anderson resigned Monday, just hours before scheduled a court hearing to hear evidence to remove him. Court documents detail the testimonies of other deputies and coworkers who say Anderson was often drunk, failed to show up at crime scenes while on duty and, according to one deputy, reported for work only four days during May last year. Mason City Police Chief Gerald Frick said in an affidavit that he doesn’t think Anderson “should have access to weapons.”
