After conducting a thorough search, I could not find any information regarding a boat ramp named Wells Springs Road in Campbell County, Tennessee. It is possible that this boat ramp does not exist or has been recently constructed without being documented online.

Without any verified information, it is difficult to determine the type of boat ramp, its width, the body of water it services, and the types of watercraft allowed. However, it is important to note that many boat ramps in Tennessee are regulated and maintained by the Tennessee Wildlife Resources Agency (TWRA). Therefore, anyone interested in using a boat ramp in Tennessee should consult the TWRA website for the latest information and guidelines.
