As heavy rains continued to belt Archuleta County Tuesday morning, floodwaters in the San Juan River reached a 55-year peak, prompting both road and school closures in Pagosa Springs.

The river’s 12.82-foot peak, which it reached around 5:15 a.m. Tuesday, is the highest water level the river has hit since 1970, a National Weather Service spokesperson confirmed Tuesday morning. It comes within inches of the highest crest in 100 years, 13.5 feet on June 29, 1927.

The floodwaters and debris caused a failure in sewer lines beneath Highway 160, closing the roadway from the intersection with Highway 84 through to Hot Springs Boulevard, the Pagosa Springs Police Department said on Facebook Tuesday morning.

The days-long flooding has prompted mandatory evacuations in the town and closed schools in the county Tuesday, the Archuleta County Sheriff’s Office said on Facebook. An evacuation shelter at the Ross Aragon Community Center — 451 Hot Springs Blvd. — remains open to anyone affected by the floods.

Weather service officials said they are expecting the waters to drop below the major flood stage by 4 p.m. Tuesday afternoon.
