Ice jam breaks loose along Big Thompson River, releasing 4-foot wall of water and ice

ESTES PARK, Colo. - An ice jam has broken loose along the Big Thompson River, releasing a 4-foot wall of water and ice. Officials sent emergency notifications to residents living down stream, but those have since been cancelled.

According to Larimer County Sheriff's Office spokesman John Schultz, the ice jam broke around mile marker 78 of Highway 34. It was first announced around 1:30 p.m.

"At this time it does not appear the road is in danger of being washed out," Schultz said at the time.

Residents downstream were advised to stay away from the river, but the emergency warnings were cancelled about 30 minutes later. Although the water level was elevated, the Sheriff's Office reported deputies observed no problems in the area.

About 20 miles of Highway 34 was heavily damaged in the canyon between Loveland and Estes Park during September's flooding.

In December, another ice jam affected parts of Golden and Boulder. The flooding resulting from that ice jam was minor, but the clogging caused by the ice did divert the creek to a new path where a trail used to be.
