What happens at each level

11.00 ft: Major flooding in Menan-Roberts area. Interstate 15 may be closed due to flooding. County road bridges will begin to wash out.
9.50 ft: Flooding can be expected in the Menan-Roberts area.
8.00 ft: Flooding near the Warm Springs Resort area is possible.
6.25 ft: Action Stage 6.25 ft. Actual flooding is limited to islands and bars and levees on both banks of the Snake River, between the US HWY 20 bridge and the Heise area. Channel changes, including flows into high water channels, may impinge upon levees in the reach and threaten their structural integrity, leading to a breach and possible flooding outside of the levee system. Actions by local agencies may include responding to potential breaches and conducting emergency repairs.
