Three Rivers Marina offers a convenient boat ramp access point to Lake Billy Chinook near Culver, Oregon. The facility provides launch access to this multi-armed reservoir, which combines the Deschutes River, Metolius River, and Crooked River arms. Paddlers and boaters should note that the Metolius arm is closed to boating until March 1st each year, so plan accordingly during early season. Recently improved road access (paved surface extending nearly to Perry South) makes the site increasingly accessible.
**Important regulations and practical details:** All boaters must operate at slow, no-wake speeds within 200 feet of the marina and ramp areas, and within 300 feet of designated swim areas. Two reservable campgrounds are located within 10 miles—Monty Campground and Perry South Campground—making this a good option for multi-day trips. The surrounding area offers additional recreation, including Haystack Reservoir and Steelhead Falls Trail (approximately 0.5 miles to the falls), providing good options for day trips or extended outings in the region.
