N.D. town evacuated as flooding pressures dam

The 50 or so residents of a N.D. town evacuated Wednesday because of a threat to a dam on a flooded creek, while nearby Valley City worried it might see new evacuations as well.

Residents of this tiny community cleared out Wednesday as water spilled over a nearby dam and began eroding it, while officials in the larger town of Valley City to the north urged thousands of people to evacuate from their homes because of a flooding threat that could persist for weeks.

National Guard soldiers in helicopters were dropping one-ton sandbags to help shore up the Clausen Springs Dam a few miles from Kathryn, a town of about 55 residents that could become inundated if the dam breaks.

"That's slowing it (water) down, and they're going to try and channel it in a way that keeps it away from Kathryn," Gov. John Hoeven said.

Residents fled to relatives' homes or a Red Cross shelter after officials went door to door Wednesday morning telling them to get out.

Fire Chief Paul Fisher was on Kathryn's Main Street, using a two-way radio to monitor the flow of three culverts outside town. If they were to break, he said, "I'll make one more sweep through town and get out of here."

There was no evidence of major flooding by early afternoon, although some homes had water in their yards and signs of seepage in basements.

Kathryn is about 17 miles south of Valley City, which is battling record high water on the Sheyenne River. The Clausen Springs Dam is on a tributary of the river.

Evacuation request to 1,450 homes
In Valley City, the elderly, disabled and people living in low-lying areas had been urged to evacuate by 6 p.m. Wednesday to make sure emergency routes were kept open. Mayor Mary Lee Nielson said that would affect about 1,450 homes — "not quite half the city" of nearly 7,000 people.

Valley City State University, with an enrollment of about 1,000, canceled its spring semester on campus, which has been torn up by dike work, and planned to offer courses online instead. It also canceled its spring baseball and softball seasons.

Valley City got word Wednesday that the Army Corps of Engineers would hold water releases from the Baldhill Dam north of the city to 6,500 cubic feet per second for two weeks.

"This is a lot of wear and tear on those dikes for two weeks," Nielson said. "We anticipate there's going to be some hot spots. But the good news is, hopefully it's just at that level."

Releases from the dam are based on inflow forecasts from the National Weather Service, and the corps must balance inflows and outflows so the dam's emergency spillway is not overtopped, a corps statement said. The latest forecast peak inflow is 11,500 cubic feet per second, the corps said.

"When you look at Baldhill and see that we're putting out 6,500 cfs, it sounds terrible, but when there's more than 9,000 cfs coming in, you can see we're holding as much as we can," Tim Bertschi, a flood engineer for the corps, said in the statement.

Nielson said the evacuation was "strongly recommended" to avoid wear and tear on the city and to clear the way for emergency and construction work.

1882 flood record surpassed
The National Guard had a Blackhawk helicopter and some high-wheeled vehicles ready in case troops are asked to assist with evacuations, Capt. Dan Murphy said.

Murphy said the U.S. Army Corps of Engineers was closely monitoring Baldhill Dam, upstream from Valley City on the Sheyenne, trying to calculate how much water the dam can hold back in its reservoir and how much can be released without adding too much to the river.

The river rose Monday above the 20-foot Valley City record set in April 1882. It reached 20.6 feet Tuesday but fell to 20.33 feet by noon Wednesday, the National Weather Service said.

The flood risk to Valley City could last a month, said Greg Wiche, director of the U.S. Geological Survey's Water Science Center in Bismarck.

Fran Aune and her stepdaughter, Deb Wacha, were moving Aune's belongings out of her duplex Wednesday. Aune and her husband, Andrew, planned to set up a camper on a higher part of Valley City and wait out the floodwaters.

"It's scary," she said. "We've been praying a lot."

The Sheyenne empties into the Red River, which is expected to reach a second flood crest of its own near Fargo this week. The Red crested at Fargo and neighboring Moorhead, Minn., late last month just short of 41 feet, after volunteers filled thousands of sandbags to raise levees above that mark. Projections of the river's second crest have been lowered to around 35.5 feet to 36 feet.
