 In Spencer, Iowa, which was flooded by record flow from the Little Sioux River, planning director Adam Severson said that nearly 2,100 of the town's 5,000 structures have been damaged, with 80 homes collapsed or uninhabitable. Across southeast South Dakota, the Office of Emergency Management has requested a joint primary damage assessment with FEMA to verify the extent of damages, and individuals have until tomorrow to submit their reports, so it will be several weeks before details start to come into focus.
