After conducting research, I was unable to find any information about a boat ramp specifically named U.S. 69 4899 in Lumberton, Texas. It is possible that the information provided is incorrect or outdated.

However, there are several boat ramps located in Lumberton that service nearby bodies of water such as Village Creek and the Neches River. The majority of these ramps are open to the public and can accommodate a range of watercraft, including kayaks, canoes, fishing boats, and larger vessels.

The specific size and regulations of each ramp may vary, so it is important for boaters to conduct research and follow posted guidelines when launching and using these facilities. Additionally, it is important for boaters to regularly check local and state regulations for any updates or changes that may affect their use of these ramps and the surrounding waterways.
