Leslie Gulch Boat Ramp provides access to Lake Owyhee's southern end via a gravel road that may be temporarily closed due to flash flooding or wet conditions; the site features a designated boat ramp parking area, pit toilets, and the nearby Slocum Creek Campground with nine campsites.

The last 10-12 miles of reservoir upstream from Leslie Gulch experiences slack water with frequent upstream winds, making it suitable for paddling and boating but requiring awareness of water level fluctuations and current conditions before visiting.
