After conducting research, I could not find any specific information on a boat ramp named Rogers County located at latitude: 36.4588089, longitude: -95.6170578 in Oklahoma. It is possible that the name or location may be incorrect or outdated.

However, based on general information about boat ramps in Oklahoma, it can be assumed that the Rogers County boat ramp would be a concrete or paved ramp with a gradual slope into the water. The width of the ramp would likely vary, but most boat ramps in Oklahoma are designed to accommodate a single vehicle and trailer at a time.

As for the body of water that the Rogers County boat ramp might service, Oklahoma has several large lakes and reservoirs that are popular for boating and fishing. Some of the most well-known bodies of water in the state include Lake Texoma, Lake Eufaula, and Grand Lake. Without more specific information, it is impossible to determine which body of water the Rogers County boat ramp might be located on.

In terms of the types of watercraft permitted on the water, this would depend on the specific regulations for the body of water in question. In general, Oklahoma requires all boats to be registered and operated in compliance with state and federal laws and regulations. Most lakes and reservoirs in the state allow a variety of watercraft, including motorboats, sailboats, canoes, and kayaks, but there may be restrictions on certain types of boats or activities in certain areas.

In summary, while I could not find any specific information on the Rogers County boat ramp in Oklahoma, it can be assumed that it would be a standard concrete or paved ramp with a variable width. The body of water it services and the types of boats permitted on it would depend on the specific location.
