After conducting research, I was unable to find any information about a boat ramp named Vista Del Lago Road 21 in Lebec, California with the given latitude and longitude coordinates. It is possible that the ramp may be a private or unofficial ramp, which may explain the lack of information available.

Without further information, I cannot determine what kind of boat ramp it is, how wide it is, what body of water it services, or what kind of craft are permitted on the water. It is important to note that boaters should always use caution and verify information before launching their craft, as conditions and regulations can change over time.
