On Saturday (Sept. 18), authorities will resume the search for the last victim of the Poudre Canyon flooding in July.

The flooding, which occurred near Black Hollow Road, killed four people — including 57-year-old Diana Brown, who has not been found. The Larimer County Sheriff's Office (LCSO) suspended the search for Brown on July 28, citing a lack of leads.

Now, officials are ready to try again. According to a press release from LCSO, more than 120 people will search for Brown between Black Hollow Road and Steven's Gulch Picnic Site this weekend.

Crews from LCSO, LCSO's Emergency Services, Larimer County Search and Rescue, Larimer County Dive Rescue Team, Diamond Peaks Ski Patrol, Diamond Canyon Fire Protection District, Loveland Fire Rescue Authority, Berthoud Fire Department, Estes Valley Fire Protection District, Poudre Fire Authority, Civil Air Patrol, Search and Rescue Dogs of the U.S., Arapahoe Rescue Patrol and the U.S. Forest Service will all take part in the search.

"Searchers will be on the roadway, shoreline, and in the river using dogs, drones, and other specialized equipment," read the release. "Please do not come to the canyon to assist, our partner agencies are ensuring we will have sufficient resources on the scene for a thorough and safe search operation."

In lieu of physical help, authorities are asking residents who wish to get involved to donate to (or join) the volunteer organizations mentioned above.

The search will take place from 8 a.m. to 6 p.m. or until Brown is located. Expect delays and use caution when driving on Highway 14 during that time.
