Big Sky Connection - Wildfires in Montana are creating dangerous flood risks in the burn scars left behind. With no vegetation, the land is unable to absorb water and acts like concrete after the flames have been extinguished. Comments from Traci Sears, Montana national flood insurance program coordinator, Montana Department of Natural Resources and Conservation.

July 25, 2024 - The Montana Department of Natural Resources and Conservation has issued flood alerts following wildfires burning huge swaths of the state.

Floods are more likely after fires because there is less vegetation on the land to absorb water. At least 64 wildfires are burning in Montana right now and the state is closing in on a thousand for the year.

While wildfires can burn quickly and threaten structures and human lives, they create another danger even after the flames are out.

Traci Sears, national flood insurance program coordinator for the department, said the blazes leave behind acres of barren land unable to absorb rain water.

"Essentially, that soil actually becomes what they call 'hydrophobic,'" Sears explained. "It will repel water almost like concrete would. It can cause situations where you don't just have flooding but you could actually have mud flows as well."

The state is creating an interactive flood plain map to track where floods are likely to happen and to help residents plan for them when heavy rains come.

The severity of the flooding varies based on the terrain and type of vegetation destroyed by the fire but Sears pointed out it can take as long as seven years for some areas to regrow shrubs and other ground cover, and longer for trees. On the positive side, Sears noted the issue is drawing more attention because the state has been making residents more aware of the threat.

"There has definitely been more awareness, I would say, in the last six to seven years," Sears observed. "Montana has been really proactive in working not just with the flooding department but also looking and working with our fire department as well, to try and coordinate on some of this messaging."

The fires in Montana have scorched nearly 90,000 acres as dry and windy conditions persist throughout the western United States.
