Lake Owyhee State Park

Call ahead This experience may be open for on-site visitation; however, offerings and/or operating procedures may have changed due to COVID-19. Please verify details before you go and visit the COVID-19 Resources page for more information.

Owyhee Reservoir is a 53-mile-long lake, filling a narrow, deep canyon brimming with colorful volcanic rock formations. Many boaters return each year to explore the desert canyon and rugged mountains. Some of the geology is visible only by boat. Anglers are awarded excellent warm water catches, especially largemouth bass, white and black crappie. The reservoir also has catfish and is occasionally stocked with rainbow trout.

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

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

No pay phones or cell phone service at the park. Volunteer hosts and staff are not always available. This is a remote recreational experience. Please prepare accordingly.

Check the Bureau of Reclamation website for current water levels.
