What Floods at Each Level

Fields and low-lying areas near the river between US HWY 20 bridge near Lorenzo downstream to the confluence of the Snake River and Henrys Fork may experience seep and ponding. The Lorenzo boat launch may be closed due to high flows.
9 ft
Actual flooding is limited to islands and bars between US HWY 20 bridge near Lorenzo downstream to the confluence of the Snake River and Henrys Fork. Channel changes, including flows between 11,000 to 15,000 CFS 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.
