Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

Fire crews and trained search dogs from the Bay Area have been deployed to Texas to assist in ongoing rescue efforts as catastrophic flooding continues across the state. As of Wednesday, more than 160 people were missing and at least 100 have died, according to the Associated Press.

The Texas Game Wardens of the state’s Parks and Wildlife Department have searched 26 miles of river since the start of the crisis and have conducted 444 rescues, said Lt. Colonel Ben Baker. The agency has deployed helicopters, drone teams, K-9 units, a variety of boats and four-wheel-drive vehicles to carry out search and rescue missions, he said.
