All search operations in the Poudre Canyon following the Black Hollow flood on July 20, 2021, have been suspended until further leads about the missing adult female are received. She is identified as Diana Brown, 57, of Texas. She was known to be with the other three victims of the flood, previously identified by the Larimer County Coroner’s Office.

LCSO Emergency Services, LCSO IA Module, Larimer County Drone Team, Larimer County Search and Rescue, and Larimer County Dive Rescue were in the canyon from the initial report of flooding on Tuesday through Sunday, 7/25/2021. 62 rescuers spent 858 hours on the search and recovery efforts on foot, in the water, with dogs, and with drones.

Between Tuesday, 7/20/2021, and Thursday, 7/22/2021, LCSO Patrol, Investigations, Reserves, and Joint Information Center had 60 personnel spend 400 hours in active search and rescue operations, in addition to response contributions from partner agencies Colorado State Patrol, Poudre Canyon Fire, US Forest Service, Colorado Division of Fire Prevention and Control, Poudre Fire Authority, UCHealth, and the Larimer County Regional All-Hazards/Crisis Response Team, all coordinated through the Larimer County Communications Center.

In addition to the seven structures destroyed, a very large amount of forest debris will continue to impact the canyon while long-term recovery efforts are underway, led by the Larimer County Office of Emergency Management.

Our thoughts and sympathy are with the survivors. This tragic incident illustrates how quickly conditions in the canyons can change, and with continuing weather patterns favoring monsoon rain over the burn scars from last year’s record setting wildfires we urge everyone to use the utmost caution while recreating in the mountains. Be aware of closure orders and weather reports, let someone know where you’re going and when you’ll be back, and if you find yourself in a flash flood climb to safety.
