Flood Risk after 416 Fire: Assessment

The National Weather Service has issued a Flash Flood Warning for Southwestern Colorado through 9 p.m. Friday and rainfall forecasts are calling for precipitation in the 416 Fire area through Tuesday.

Because large-scale wildfires such as the 416 Fire dramatically alter the landscape and ground and soil conditions, drainages in the 416 Fire area are particularly susceptible to mud and debris flow.

Residents in the burn area – and throughout La Plata County – should be prepared for potential flooding as well as mud and debris flow.

An interdisciplinary team of hydrologists, soil scientists, engineers, weed specialists, archaeologists, wildlife/fisheries biologists and GIS analysts completed an assessment this week of where post-fire flooding and debris flow might occur, as well as other impacts the area could see in the months and years following the 416 Fire.  Below are some of the resources the team produced.
