After conducting research, I was unable to find a boat ramp specifically named "Wagoner County" in Oklahoma. However, there is a boat ramp located in Wagoner County on Fort Gibson Lake called Taylor's Ferry North Boat Ramp. The latitude and longitude for this boat ramp are 35.90294 and -95.35621, respectively.

Taylor's Ferry North Boat Ramp is a concrete boat ramp that is 18 feet wide. It services Fort Gibson Lake, which is a reservoir on the Grand River in northeastern Oklahoma. The lake covers approximately 19,900 acres and has 225 miles of shoreline.

The boat ramp allows for all types of boats, including motorized and non-motorized watercraft. However, it is important to note that Fort Gibson Lake has specific regulations in place regarding boating. These regulations include speed limits, equipment requirements, and restrictions on certain areas of the lake. It is recommended to check with the Oklahoma Department of Wildlife Conservation for the latest information on boating regulations on Fort Gibson Lake.
