Lowman, Idaho, September 5, 2019 - The Boise National Forest is temporarily closing Forest road 579 from Sept. 16 – Sept. 29 to replace a culvert with an Aquatic Organism Passage (AOP) structure. The AOP will accommodate post fire flows or runoff as a result of the Bearskin Fire. When awarded, the work will be managed by Valley County and OK Gravel Works, a local contractor from Cascade, Idaho.


“We want to give the public, particularly archery hunters, enough notice since some may have plans to hunt in this area of unit 34 (Sawtooth Zone) during construction,” said John Kidd, Lowman District Ranger. “We encourage them to plan accordingly because a section of Forest road 579 will be closed and impassable for a short time.”


A detour around the road closure will be via Forest roads 555, 591, 510, 582 and 563 (see attached map). Forest users should also travel cautiously since they may encounter logging traffic along the detour route.


The work will also reduce the risk of culvert failure which could damage the popular forest road used by summer recreationists and winter snowmobilers.


The Bearskin Fire Burned Area Emergency Report completed in 2017 recommended this treatment to avoid impacts to water quality and riparian areas. The existing culvert is a migration barrier and upgrading this culvert to an AOP structure will open up about 0.6 miles of stream habitat to bull trout colonization within the Deer Creek drainage as well as reduce sediment delivery to critical bull trout habitat.
