• The city had to extend one of its levees by about 600 feet and that work is finished. On Thursday, Sioux City crews helped property owners fill sandbags as a precautionary measure, he said.
• At The Railroad Museum near the river in Sioux City, volunteers helped staff move artifacts to higher ground because the main building will likely get about 5 feet of water, said museum executive director Matt Merk. Vintage rolling stock including a 1943 General Electric diesel locomotive was among exhibits moved to safety, Merk said.
• "At the very worst at this point we'll have cleanup and nothing completely damaged except for some sheet rock," he said.
• Crews were building a temporary levee that will run across Interstate 29. It should protect much of North Sioux City but will close off a few miles of the interstate and force motorists onto local roads between Sioux City, Iowa, and Sioux Falls, South Dakota, to the north.
• The river level is expected to peak at about 4 feet below the levee height, said Nathan Sanderson, a policy adviser to South Dakota Gov. Dennis Daugaard. He said the interstate will be closed for at least 36 hours but that it's difficult to predict how much longer after that.
• Floodwaters blocked most of the roads connecting South Dakota and Iowa between Sioux Falls and Sioux City.
• Dennis and Dottie Oleson's house in Akron, Iowa, sits on high ground so they haven't had to deal with flooding. A levee breached early Wednesday in the town, causing flooding in a business district, but a temporary patch is holding.
• "The water was a lot higher yesterday," Dennis Oleson said.
• He and his wife drove about 6 miles south of the town to see how the floodwaters overtook the Iowa State Highway 3 crossing into South Dakota. The heavy rains created a giant lake far wider than the Big Sioux just to the east, and several tiny fish were trying to wiggle their way across the two-lane road against the flow.
• Dakota Dunes, South Dakota, a community between the Big Sioux and Missouri rivers is potentially vulnerable. The existing levee has been raised and city officials said they're confident it will hold the Big Sioux back, but they have an evacuation plan.
• Jefferson, South Dakota, about 7 miles north of North Sioux City, hired a local contractor to build a 3-foot-high berm around the northeast side of the town of nearly 550 to hold back the Big Sioux.
• "If we get it, it would probably be just part of town," Police Chief Bill McKelvey
