Lake Owyhee State Park's McCormack Campground sits at the end of a narrow, winding, single-lane road that runs along the edge of a steep cliff above the reservoir. The drive in is roughly 15 minutes of concentrated attention, and campers towing trailers longer than 25 feet should factor that into their planning. No cell service reaches this area, and the nearest medical facilities are approximately 40 miles out. Those realities set the tone for the kind of trip this is.
The campground itself is well-maintained and consistently reported as clean, with full hookups (electric, water, and sewer), showers, and a dump station available on-site. Sites face open terrain near the lake, and several reviewers noted clear sightlines over the water from their spots. Fishing, kayaking, boating, and paddleboarding are the primary draws. Water levels fluctuate noticeably by season, and low water years can mean hauling watercraft a quarter mile over rocks and gravel to reach the shoreline. The Indian Creek Campground and Lake Owyhee State Park Campground are both within a half mile for campers who want to compare options within the park.
The access road follows the Owyhee River and passes a hot spring and a one-lane tunnel, with multiple dispersed sites on BLM land along the river corridor. As Erik C. put it after an off-season stay: "No ranger, no campers, just us and the lake and the deer." McCormack works best for self-sufficient campers, anglers, and paddlers who can handle a remote setting and don't need connectivity.
Description
Lake Owyhee State Park is a remote oasis on the eastern edge of Oregon that offers camping and boating on the shore of a scenic desert canyon reservoir. The park contains two campgrounds along Owyhee Reservoir, a 53-mile-long lake that fills a narrow, deep canyon brimming with colorful volcanic rock formations.
The Gordon Gulch Day-use Area is open year-round and includes picnic tables and a boat ramp. Many boaters return each year to explore the desert canyon and rugged mountains. Some of the reservoir's incredible geology is visible only by boat. Anglers are awarded excellent warm water catches, especially large mouth bass, white and black crappie. The reservoir also has catfish and is occasionally stocked with rainbow trout. Look for golden eagles, coyotes, ground squirrels, rabbits, pronghorn antelope, mule deer, and wild horses (watch out for rattlesnakes, too). You might even see California bighorn sheep or a mountain lion.
