The Forest Services had completed a Burn Report for the Four Corners fire. Among the findings include:

• 2% of the acres burned did so at a high soil burn severity.
• 562 acres burned were on private property.
• A rough estimate of 19% of the fire area is assumed to have fire-induced water repellency.
• The primary threats caused by the fire include increased runoff, which is expected to intensify the first 2 to 5 years following the fire until the burned watersheds recover, and accelerated hillslope erosion, which would result from amplified runoff and decreased infiltration rates. High intensity, short duration rainfall may result in sediment loading, localized debris flows, and valley bottom flooding, primarily in the Sheep Creek, Bull Corral, Poison, Van Wyck, French, Hazard, Campbell, Skein Lake, Silver creek, Bed Ground creek drainages. Additional threats include falling trees and rolling rocks originating from destabilized hillslopes in the burned area.

Because of this it is strongly recommended that property owners downhill of the burn scar obtain flood insurance. The flood insurance policy will cover owerns in the event of mudflows off the burn scar. The risk of mudflow coming off the burn scar will exist for up to seven (7) years.
