The children, aged four and seven years old, and a man were swept downstream and later found dead, the mountain resort village said late yesterday on its website, adding that rescue operations were underway. Dramatic video footage on social media and various news outlets showed an entire house, ripped from its foundations, careening downstream through the brown, muddy waters of the flood-engorged Rio Ruidoso, side-swiping trees as it went. "I've seen the video. We don't know if anyone was in the house," said Danielle Silva, a spokesman for the New Mexico department of homeland security and emergency management. Emergency teams organised by local law enforcement and the national guard conducted at least 85 swift-water rescues in and around Ruidoso, many of them people stranded in cars and homes by elevated flood waters, Silva said. Silva said the river had quickly risen by a provisional record of 6.2m at the peak of the flood, and as waters began to recede in the evening, authorities began searching for survivors in the debris. The latest floods come just four days after a deadly flash flood triggered by heavy rains along the Guadalupe River killed at least 109 people and left scores missing after ravaging a swathe of Texas Hill Country. In New Mexico, Silva said the severity of the debris flow was heightened by a flame-scarred landscape stripped of vegetation in a wildfire which was then followed by flooding that eroded the soil. Ruidoso, a popular summer retreat as well as ski resort nestled in the Sierra Blanca mountain range of south-central New Mexico, is located about 185km south of Albuquerque, the state's largest city.
