After conducting a search, I was unable to find any specific information regarding a boat ramp named Jefferson Dock Road Arrowhead in Virginia. It is possible that the provided coordinates could be inaccurate or outdated.

It is important to note that there are numerous boat ramps located throughout Virginia, each with their own regulations and specifications. It is recommended to refer to local and state resources, such as the Virginia Department of Wildlife Resources, for accurate and up-to-date information on specific boat ramps and their usage.
