Another one of Boulder’s popular tubing locales will face closures as water levels rise, creating dangerous conditions.

Boulder Creek — which stretches from below Boulder Falls under Highway 119 to 55th Street in the city of Boulder — was officially closed for tubing as of 5 p.m. Wednesday evening, according to a press release from the Boulder County Sheriff’s Office.

Single-chamber flotation devices, such as blow-up rafts and inflatable paddle boards, are also banned from the creek.

Water levels reached around 701 cubic feet per second on Wednesday, with levels expected to rise after spring run-off and the scheduled release of water into the creek from the Barker Reservoir.

“Increased risks which are present during higher water flows include cold water temperatures, floating debris and obstructions in the water, which can snag a person,” the sheriff’s office said.

Two rafters, Brent Boulter, 57, and Dylan Wallace, 27, died in rafting accidents in Colorado earlier this month, according to American Whitewater.

The Boulder Sheriff’s Office, which determines water closures in the county, recently closed down the North Saint Vrain and Saint Vrain rivers to tubing on Friday due to high water levels, as well.

Clear Creek also enacted restrictions on June 5 due to swift-moving water and debris.

These temporary water restrictions extend from the western boundary of unincorporated Jefferson County through the eastern limits of the City of Golden, including Vanover Park, and will remain in place until water levels decrease.

All of the restrictions and bans — including Boulder Creek — will remain until further notice once water levels subside.

Kayaks and white-water canoes are still permitted on the waterways, but the office warned that kayakers should still safety gear due to water levels.

“We urge community members to always be safe when recreating around water, and especially now when the waters are high and moving fast,” Parks and Recreation Director Ali Rhodes said in the release. “Swift, cold water is dangerous and conditions can change quickly.”

Violations of the closure are a civil infraction and will result in a $100 fine, the office warned.
