Bombshelter is a Class IV-V rapid located on the main Owyhee River between Three Forks and Rome, part of a challenging pool-and-drop section recommended only for highly skilled whitewater boaters.

The rapid features steep drops and heavy hydraulics typical of this middle section, requiring careful scouting and precise maneuvering; this section is best run in medium-sized rafts (14-15 feet), kayaks, or catarafts when water flows are between 1,500-3,000 cfs at the Rome gauge.
