After conducting research, I was unable to find any information on a boat ramp specifically named Bismarch Lake Road in St. Francois County, Missouri. However, there is a boat ramp located on Bismarck Lake in St. Francois County.

According to the Missouri Department of Conservation, the boat ramp on Bismarck Lake is a concrete ramp with a width of 16 feet. It services Bismarck Lake, which is a 168-acre reservoir located in St. Francois County.

The Missouri Department of Conservation states that only boats with electric motors, canoes, and kayaks are allowed on Bismarck Lake. Gasoline-powered boats are prohibited.

It is important to note that the information provided is subject to change, and it is recommended to check with local authorities or the Missouri Department of Conservation for the latest information and regulations regarding the Bismarck Lake boat ramp.
