ALBUQUERQUE – The New Mexico National Guard and other rescue crews evacuated dozens of campers and residents who were stranded by floodwaters along the Pecos River as New Mexico was drenched Thursday by another round of record rainfall.
While the welcomed moisture is helping the state out of an unprecedented drought, the runoff was threatening an RV park near Brantley Lake and had pooled up around the community of Lakewood. Crews were using boats and helicopters to bring about 70 people to dry land, where they were checked by medical personnel and bused to a shelter in Carlsbad.
National Guard officials said they were concerned floodwaters could breach a channel above the lake and spread out into an old lake bed, flooding the area and posing “life-threatening events.”
Empty reservoirs along the Pecos River were filling up with muddy water Thursday afternoon, as northern New Mexico braced for its share of the moisture. Officials said areas with recent wildfire burn scars and mountain slopes – and places downstream from those areas – would be particularly vulnerable to mudslides and flooding.
“The rainfall totals from when this event began are going to be record-breaking. They already have been,” said Kerry Jones, a National Weather Service meteorologist in Albuquerque.
Jones said it’s likely some areas could see 6 to 10 inches of rain by the weekend. In one spot in the Guadalupe Mountains of southern New Mexico, more than 11 inches fell in a 24-hour period, which forecasters described as “unbelievable.”
The rain-soaked plains of eastern New Mexico were shedding runoff into arroyos that were draining into the Pecos River. At Avalon Dam just north of Carlsbad, federal water managers reported flows of 6,000 cubic feet per second. There’s typically zero to little flow through the area at this time of year.
Authorities issued a plea for people to stay away from the river and the dam.
Another concern was the floodwaters flowing down the river and combining with runoff coursing through a large canyon near the southern edge of Carlsbad. By Thursday evening, the river’s flow had reached about 13,000 cubic feet per second.
“We’re watching everything very closely,” said Mary Perea Carlson, a spokeswoman for the Bureau of Reclamation.
Although water levels in all reservoirs along the Pecos have increased significantly in the last 24 hours, Perea Carlson said plenty of storage space remains and all structures remain sound.
The city of Carlsbad closed a bridge along U.S. Highway 285 as a precaution.
Volunteers with the American Red Cross were manning shelters in Chaves and Doña Ana counties to help motorists and residents affected by floodwaters.
Officials at Carlsbad Caverns National Park closed the park Thursday and asked all employees and visitors to leave because of the potential for flooding along the park’s main road. They planned to reopen the park this morning.
Near Alamogordo, two rain-caused rock slides on both sides of a tunnel on U.S. Highway 82 closed the highway briefly Wednesday.
