The proposals are designed to reduce the spread of noxious weeds, reduce the risk of erosion and failure of Forest roads and trails, reduce hazards at recreation sites, and promote the development of an early warning system for residents within the Main Salmon River Canyon. The risk of increased erosion and runoff will decrease as the vegetation re-establishes on steep Canyonlands. The emergency treatments listed below will be implemented over the next year to protect the identified values at risk.
Noxious weeds: Treatment includes survey, spraying, and monitoring of sites considered to be at increased risk of noxious weed spread due to moderate and high burn severity and proximity to known weed populations, roads and trails, or other areas disturbed by suppression actions, such as dozer lines, fire lines, helispots, drop points or spike camps.
Road Treatments: Several roads within the fire area were determined to be at very high risk of erosion and failure due to undersized culverts, steep slopes, and moderate and high burn severity. The planned actions include maintenance of drainage features and culvert removal and replacement. Treatments are designed to reduce the risk of road failure and erosion due to plugged culverts or cut and fill failures, which could potentially result in increased sediment delivery to streams identified as important fish habitat. Treatments include the repair of a bridge on FS Road 50161 over Lake Creek, removal of hazard trees, and temporary closure of the Lake Creek Road (FS 50161) during times when there is a high risk of flooding. Additionally,installation of road signs burned by the fire and additional new fire hazard signs, will occur to protect public safety.
Trail Treatments: Trail crews will maintain, repair, rebuild, and add water management structures where needed on trails affected by moderate and high burn severity. Work will include removing rocks, debris slides, and burnt snags that have fallen onto or across trails. A determination was made to keep the Patrick Butte Trail (#153) closed for public safety until treatments can be implemented. Fire hazard signs and other informational fliers will be placed in strategic locations entering the burn areas.The majority of trail work will be conducted in the spring and summer of 2016.
Recreation Treatments: Protection and monitoring of the water system at the Spring Bar Campground and monitoring for public safety hazards at other developed and dispersed sites will be conducted. Monitoring of tree mortality and removal of hazard trees that may threaten infrastructure and public safety will also occur.
Early Warning Detection System: Intense storm events can generate flood flows and debris torrents in the first few years after wildfire which could pose a threat to residents in the Salmon River Canyon. Coordination with Idaho County, the National Weather Service (NWS), and National Resource Conservation Service (NRCS) will continue to occur to facilitate the development of an early warning system for residents when weather events could potentially pose a threat to public safety.
