According to the Florida Fish and Wildlife Conservation Commission's website, the Fisher Old Miller Road 11198 boat ramp in Santa Rosa County is a single-lane concrete ramp with a courtesy dock. The ramp is approximately 20 feet wide, making it suitable for smaller boats and trailers.

This boat ramp services the Blackwater River, which is a popular spot for recreational boating and fishing. The Blackwater River is a freshwater river that flows into the Blackwater Bay and ultimately into the Gulf of Mexico.

The website notes that all types of watercraft are allowed on the Blackwater River, including motorized and non-motorized vessels such as canoes and kayaks. However, boaters are advised to check local regulations and safety guidelines before heading out on the water.

It's important to note that the accuracy of this information may change over time, and it's always a good idea to check with local authorities or reliable sources for the latest updates on boat ramps and waterway regulations.
