Salmon Falls Creek Reservoir is a 17-mile long serpentine lake in Twin Falls County, Idaho, formed by the Salmon Falls Dam. The reservoir is popular for fishing, boating, and paddling. Kayakers and canoeists can explore the expansive waters, but should be aware of afternoon crosswinds that can make paddling challenging. It's best to set out early in the day to avoid difficult conditions.

The reservoir is renowned for trophy-sized walleye fishing, with a bag limit of six. Other species include crappie, bluegill, and bass. Several boat ramps provide easy water access. The shoreline offers numerous level areas for shore fishing as well.

Lud Drexler Park, managed by the BLM, is located on the northeast tip of the reservoir near the dam. It provides 20 primitive RV campsites with grills, picnic tables, and fire rings. The campground has drinking water, vault toilets, and a dump station. Sites can accommodate RVs up to 25 feet, with a few spots for 35-foot rigs. The campground operates year-round on a first-come, first-served basis.

For paddlers seeking whitewater, Salmon Falls Creek offers class II and III rapids from April to mid-June when water levels are higher. The creek flows into the Snake River and features scenery similar to the Jarbidge and Bruneau River canyons.

The area around the reservoir includes multi-use trails for hiking and off-roading in Salmon Falls Creek Canyon. Wildlife viewing opportunities exist in the area. The reservoir freezes in winter, allowing for ice fishing.

Access to the reservoir is via US Highway 93, which runs along the eastern shore. The nearest major town is Twin Falls, about 22 miles away. Visitors should come prepared, as amenities are limited in the immediate vicinity of the reservoir.
