Deadwater Spring provides boat ramp access to the North Fork of the Salmon River in the Lemhi County backcountry. This location sits on a major river system—the Salmon River is a stream order 8 waterway with significant volume (averaging over 13,000 cubic feet per second) and a steep gradient of 23.1 feet per mile, making it suitable for experienced paddlers and boaters. The site is positioned near the river's headwaters in a mountainous region with substantial elevation changes.
**Important seasonal considerations**: Winter and early spring conditions can impact access at this site. Ice jams historically affect boat ramps in this area, and Deadwater Spring has been among the ramps impacted by seasonal ice. Always check current conditions before launching, as the Salmon River's high flow and steep gradient create dynamic conditions that can change rapidly. Nearby alternatives include the Carmen and Tower Rock ramps (when accessible). Campgrounds in the area include Tower Rock Campground and Wallace Lake Campground within 10 miles.
Plan ahead for this remote access point and verify ramp conditions with Idaho Department of Fish and Game before your trip.
