The Upper Tenmile Watershed is located southwest of the city of Helena, Montana, on the Helena National Forest (HNF). The watershed is an important source of drinking water for the city and is also a popular recreational area for nearby residents.
The HNF has proposed treating fuels in the Tenmile-South Helena project area which encompasses the 26,000 acre watershed and an additional 35,000 acres to the east of the watershed. The Tenmile-South Helena project proposes hazardous fuel treatments for the purpose of “maintaining consistent water quantity-quality within Helena's municipal watershed and improving conditions for public and firefighters safety across the landscape in the event of a wildfire” (Helena National Forest, 2014).
In April, 2015 the HNF requested that the Fire Modeling Institute (FMI) conduct a wildfire probability modeling and risk assessment study to analyze proposed fuel treatments in the project area. The HNF requested this study include modeling the probability of burning, potential fire behavior, and identification of areas where large fires and/or fires potentially destructive to structures were most likely to originate.
