Flood Recovery & Operations
Beginning June 12, 2022, unprecedented amounts of rainfall caused substantial flooding, rockslides, and mudslides within Yellowstone National Park. Historic water levels caused severe damage to roads, water and wastewater systems, power lines, and other critical park infrastructure. Check the flood recovery and operations page for up-to-date information and updates on flood recovery efforts and park operations.
Never approach animals or block traffic to view them. The animals in Yellowstone are wild and unpredictable, no matter how calm they appear to be. Always stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from all other animals, including bison and elk.
