After conducting research, I was unable to find any information on a specific boat ramp named US 95 Idaho County in Idaho. It is possible that the ramp may have a different name or is not a publicly accessible ramp. Therefore, I am unable to provide information on the width of the ramp, the body of water it services, or the types of watercraft that are permitted on the water.

In general, boat ramps can vary in size and design based on their location and purpose. Some ramps may be narrow and designed for small watercraft such as kayaks or canoes, while others may be wider and designed for larger boats. The body of water that a boat ramp services can also vary and may include lakes, rivers, or the ocean.

To ensure accuracy when researching boat ramps, it is recommended to use reliable sources such as state or local government websites, boating associations, or official boating guides.
