Iowa’s Hawkeye River floods again after being closed for more than three weeks

The Iowa Department of Natural Resources is reopening the Hawkeye and its tributaries this week after a major snowstorm caused flooding and mudslides across the state.

State Natural Resources Director Paul Kallberg said Friday that the water treatment plant at Hawkeye Dam, which is near the intersection of the two rivers, will reopen to full flow on Monday.

The Hawkeye, a 4,000-acre river that feeds into the Mississippi River, was closed to downstream flow until mid-December.

Kallberg declined to release any new figures on the number of homes that have been flooded since last week’s flooding.

He said there were no fatalities and no injuries.

But a water tanker was hit by a pickup truck as it was trying to cross the Hawkeyes tributary and spilled more than 1,000 gallons of diesel fuel, according to the state, which said the fuel spilled onto a bridge that crosses the Hawkes Lake.

More than 200 vehicles were also damaged by snowdrifts on the tributes and the reservoir, and hundreds of trees were uprooted, said state officials.

The dam is now open for downstream flow, Kalleng said, but that will take some time.

He said the reservoir at the dam will be open on Monday after a snowstorm and ice removal.

The Hawkeye has been closed to upstream flow since December.

The reservoir is currently about 10 feet (3 meters) below normal water levels, but Kallenberg said that was because the river had been diverted to reduce its current flow.

The reservoir is about 12 feet (4 meters) above normal levels.

It took about 24 hours to clear snow and ice from the Hawke and its lower tributy, Kullberg said.

A state of emergency was declared in Iowa in December after heavy snow and icy conditions caused flash flooding and flooding in Iowa City.

The state imposed mandatory evacuations for some communities in western Iowa.
