According to the latest information available, the Kern Canyon Road Bodfish boat ramp is a concrete and paved single-lane ramp that is approximately 12 feet wide and 140 feet long. It services the Lake Isabella reservoir, which is located in Kern County, California. The reservoir covers approximately 11,000 acres and is a popular spot for boating, fishing, and other recreational activities.

As for the types of watercraft allowed on Lake Isabella, motorized boats and personal watercraft (such as jet skis) are permitted, as long as they meet California State Parks regulations regarding safety equipment and noise levels.
