H.R. 10529, the A River Runs Through It Act, designates and manages approximately 207,747 acres of land in Montana for conservation and recreation purposes. The bill establishes six forest restoration areas covering about 183,633 acres where the Secretary of Agriculture will implement fire-resilient forest management through prescribed burning and vegetation treatments while allowing continued livestock grazing and restricting new permanent roads. The legislation also designates two winter recreation areas totaling approximately 12,114 acres where over-snow vehicles are permitted under existing regulations, and creates new wilderness areas to be managed by the Forest Service according to the Wilderness Act while allowing continued livestock grazing and fire management activities. The bill protects Native American treaty rights and tribal land management authority, ensuring the designations do not infringe on existing tribal sovereignty. The legislation contains no specified federal funding amount or authorization timeline in the provided sections, leaving implementation details to the relevant federal agencies.
