Based on the latest information available, the boat ramp named Walnut Creek in Pennsylvania is a concrete boat ramp that is 20 feet wide. It services Lake Erie, which is a large body of water that borders Pennsylvania and several other states.

According to the Pennsylvania Fish and Boat Commission, which manages the ramp, it is suitable for a variety of watercraft, including power boats, sailboats, and personal watercraft (such as jet skis). However, there are some restrictions in place to ensure safety and protect the environment. For example, all boats must have a valid registration from the state of Pennsylvania or another state, and all operators are required to have a boating safety education certificate if they were born after January 1, 1982. Additionally, there are certain areas of the lake where speed limits and other regulations may apply, so it's important for boaters to be aware of these rules and follow them to avoid fines or other penalties.

Overall, the Walnut Creek boat ramp offers convenient access to Lake Erie for boaters in the region, and provides a safe and well-maintained launch site for a variety of watercraft.
