Lake Owyhee State Park

Symbols represent major park features & activities. Blue icons mean some/all are ADA accessible.

Lake Owyhee State Park is a remote oasis catering to camping and boating on the shore of a scenic desert canyon reservoir. 

Owyhee Reservoir is a 53-mile-long lake, filling a narrow, deep canyon brimming with colorful volcanic rock formations.  Many boaters return year after year to explore the desert canyon and rugged mountains. Some of the geology is visible only by boat.  Anglers are awarded with excellent warm water catches, especially for largemouth bass, white and black crappie.  The reservoir also has catfish and is occasionally stocked with rainbow trout.  The Indian Creek campground and the Gordon Gulch Day-use area have boat ramps.  Another ramp is near the dam.  Marine fuel, firewood and ice are available for sale.

The road to Lake Owyhee Reservoir is a very scenic and picturesque drive, but please drive cautiously. The roadway is narrow and moderately steep. Drive slowly and be prepared to yield to other campers and boats as you enter and leave this recreation area.

Follow park rules and boating safety regulations.  The nearest emergency services are 33 miles away, in Nyssa. The closest hospital is in Ontario, and about an hour's drive from the park.
