Dawson City ice bridge looking uncertain again this year

People in Dawson City are wondering if they'll see a useable ice bridge form across the Yukon River this winter because so far, it doesn't look promising.

"What we've got is a repeat of the last couple of years," said Jesse Cooke, who lives in West Dawson, across the river from the main town site.

"Now three years in a rowthe river is jammed, upriver from Dawson, and that leaves a big open lead of water right in front of town where the typical ice bridge would be."

Each winter since the 1960s, the Yukon government has maintainedan ice crossing. It's usually open for at least two or three months, allowing the 100 or so residents of West Dawsontodriveto and from thedowntown.

Thingschanged two winters ago, when the usual crossing spot failed to freeze over.Dawsoniteshad to find their own routeacross the river, travelling at their own risk. The same thing happened last year.

The government attemptedto help the river freeze over last year by spraying water at the ice edge, but that $120,000 experiment was canned after a week.

Cooke believes the persistent patch of open waterrepresents anew norm, and Dawsonitesshouldn't count on the river freezing over eachwinter. He says it may have to do with climate change, or the changing contours of the riverbed.

"Last year was a typical winter it was very cold, and we had lots of stretches of 40. It's not that the river didn't freeze it froze up nice and solid,just in the wrong spot," he says.

No plan yet

A report done earlier this year for the Yukon government by the National Research Council was inconclusive on why freeze-up has been different in recent years. It cites upriver ice jams, an evolving riverbed, climate change, and effluent from the Dawson City wastewater treatment plant as possible factors.

The report also suggests a number of ways the government might respond, including using an ice boom, extending a tow line across the channel, or trying again tospray ice at the river (according to the report, last year's attempt failed, in part, because of warm weather, last-minute planning, and failure to use an ice boom).

The Yukon government has not said what its plan is this winter. Earlier this fall, it put out a request for proposals to build an ice bridge, possibly using an ice boom, but a contract has not yet been awarded.

According to the tender document, construction of the bridge is to start no later than Dec. 15.

Cooke was not willing to wait he and his family decided to move into town for the winter, just to be safe.

"What we've got is a repeat of the last couple of years, so we're kind of glad that we made the move," he said.

"I hope it's not a new normalas in, like, we're never going to get an ice bridge again. Because thatjust can't happen we have to figure out a solution. And by 'we,' I mean us as residents, but I mean the Yukon government, too."
