The Blue River is open for business.

SILVERTHORNE — The Blue River is open for business.

The Summit County Sheriff’s Office announced Tuesday afternoon that the Blue River had returned to safe conditions would be reopening for recreational activities immediately.

On June 1, the Sheriff’s Office and the town of Silverthorne were notified by Denver Water that flow levels were rapidly increasing to 1,000 cubic feet per second, presenting safety concerns for river recreationists.

Sheriff Jaime FitzSimons and Silverthorne Police Chief John Minor decided to temporarily close the river from the base of the Dillon Dam to the Sixth Street Bridge, where the water was high enough to injure someone floating past that point.

On Tuesday afternoon, the Sheriff’s Office and town got the thumbs up from Denver Water that flow levels on the river had significantly decreased and were once again safe for recreation. At 1 p.m. Tuesday, the Blue River below Dillon Dam was flowing at 301 cfs.

While the river has opened back up, officials are reminding anyone heading out on the water to use caution. Members of the public are encouraged to review the Summit County Swift Water Safety and Flood Preparedness Guide available on the county’s website. The guide contains information on the history of high water events in the county, along with instructions for building sandbag levees, household checklists, flood insurance information, safety tips for recreating and more.

“In light of the reopening of the river, I want to remind the recreating public to always remain vigilant of changing river conditions and always wear a personal floatation device when recreating in or around any river or body of water,” FitzSimons said.
