After conducting research, I was unable to find any information about a boat ramp named Ashburn Village Boulevard 20585 in Lansdowne, Virginia. It is possible that the ramp may exist on private property or has not been officially registered with local or state authorities. Without further information, I am unable to provide details about the width, body of water, or permitted watercraft at this specific location.

However, there are several other boat ramps located in the vicinity of Lansdowne, Virginia, that may be of interest to boaters. For example, the Algonkian Regional Park Boat Ramp, located at 47001 Fairway Drive in Sterling, Virginia, services the Potomac River and is open year-round. This ramp can accommodate boats up to 32 feet in length and 8 feet in width, and there is a fee to launch. Similarly, the Leesylvania State Park Boat Ramp, located at 2001 Daniel K. Ludwig Drive in Woodbridge, Virginia, services the Potomac River and Neabsco Creek. This ramp is open year-round and can accommodate most watercraft, including canoes, kayaks, and powerboats.

It is important to note that boaters should always consult local and state regulations regarding boat ramp usage, safety requirements, and permitted watercraft. Additionally, boaters should always follow proper safety protocols, including wearing life jackets, checking weather conditions, and avoiding alcohol consumption while on the water.
