After conducting research, I was unable to find any specific information about a boat ramp named Cedar County at the given latitude and longitude in Missouri. It's possible that the information provided is incorrect or outdated.

However, I can provide general information about boat ramps in Cedar County, Missouri. According to the Missouri Department of Conservation, Cedar County has several public boat ramps located on Stockton Lake. These ramps can accommodate a variety of watercraft, including fishing boats, ski boats, pontoon boats, and personal watercraft.

The width of the boat ramps may vary depending on the location, but they are typically designed to accommodate two or more boats launching or retrieving at the same time. Additionally, some of the ramps may have a courtesy dock or parking lot nearby for easy access.

It's important to note that regulations for watercraft on Stockton Lake may change, so it's always best to check with local authorities or the Missouri Department of Conservation for the most up-to-date information.
