Lost Valley Reservoir is a scenic 726-acre mountain lake located in Adams County, Idaho, offering a reliable launching point for kayakers, canoeists, and motorboats. The primary boat ramp is located on the southeast shore of the reservoir, with an improved double-lane ramp also available on the southwest end. The reservoir sits at an elevation of 4,770 feet and is surrounded by coniferous forest, making it an attractive destination for water recreation and fishing. Note that water levels drop significantly by late summer, so early season paddling is recommended.
The Lost Valley Reservoir Dispersed Camping Area provides numerous free campsites adjacent to the reservoir, though amenities are minimal—no hookups, trash receptacles, or facilities beyond basic toilets. Paddlers should plan accordingly and pack out all trash. The site is accessed via US Highway 95, approximately 8 miles southwest of New Meadows, then east on Forest Road #89. Nearby improved campgrounds with reservations available include Cold Springs Campground and Evergreen Campground, both within 10 miles. This location is ideal for calm-water paddling and makes a good base for exploring the scenic reservoir and surrounding Payette National Forest.
