BLM expands Tartar Fire closure across Idaho public lands
The Bureau of Land Management expanded its temporary closure of public lands, roads and trails in southwestern Idaho on August 2 because of the Tartar Fire and related suppression and stabilization work.
The expanded order covers BLM-managed lands within the Four Rivers Field Office area. It is scheduled to remain in effect through August 24, 2026, at 11:59 p.m., unless BLM changes or lifts it sooner.
What changed
The August 2 action expands the narrower closure announced July 27 for BLM-managed lands east of Brownlee Reservoir. The original order began July 27 at noon and was scheduled to remain in effect through August 17 at 11:59 p.m.
The expanded closure is bounded by the Snake River below Weiser on the west and south. From there, the boundary follows Weiser River Road east, then runs north to U.S. 95 and Cambridge. Highway 71 and the Payette National Forest form the northern boundary before the area returns west to the Snake River.
Within that footprint, the order applies to BLM-managed public lands, roads and trails. It is not a blanket closure of every property or route around Brownlee Reservoir.
Why BLM closed the area
BLM said the restriction is intended to protect visitors and firefighters involved in active suppression operations. The agency also cited post-fire emergency stabilization and rehabilitation activities.
Those operations can involve fire crews, equipment and changing access conditions. BLM said the expanded closure was necessary to support public and firefighter safety while the Tartar Fire response continues.
What is outside the order
The closure applies to lands managed by the Bureau of Land Management. Private land is not automatically covered by the federal order, although separate restrictions may apply under other land-management or local actions.
Visitors should verify land ownership and the status of individual roads, trails and recreation areas before traveling near the closure boundary. A road or property outside the BLM-managed footprint is not necessarily covered by this order, but it may be subject to a separate restriction.
What visitors should do
Anyone planning to travel near Brownlee Reservoir, Weiser, Cambridge or adjoining BLM roads and trails should check the BLM Idaho Advisories and Closures page immediately before leaving. Fire conditions and access orders can change as suppression and stabilization work develops.
Visitors should also review current incident-specific fire information and should not enter closed BLM lands, roads or trails.
The Four Rivers Field Office can provide direct closure information at 208-384-3300.
What to watch next
The order is temporary. BLM could narrow, extend or lift it before or after the scheduled August 24 end date, depending on fire behavior, suppression needs and the safety of public access.
National Interagency Fire Center reporting for August 2 listed seven large fires in Idaho and advised residents and visitors in affected areas to monitor official fire information, road closures and other local safety updates. That broader context reinforces the need to rely on current agency notices rather than older travel plans.
