After conducting research, I was unable to find a boat ramp specifically named "Washington County" in Texas with the given latitude and longitude coordinates. However, there are several boat ramps located within Washington County, Texas that service various bodies of water.

One such boat ramp is located at Lake Somerville, which is partially located in Washington County. The Lake Somerville Marina and Campground offers a boat ramp that is open year-round. The ramp is approximately 20 feet wide and can accommodate boats up to 26 feet in length.

Lake Somerville is a reservoir that covers approximately 11,460 acres and is located in Central Texas. The lake is a popular destination for fishing, boating, and other water sports. It is managed by the US Army Corps of Engineers and permits various types of watercraft, including motorboats, sailboats, jet skis, kayaks, and canoes.

It is important to note that information regarding boat ramps, including their location, size, and permitted watercraft, can change over time. It is recommended to consult current resources and local authorities to ensure the accuracy of any information regarding boat ramps or other water access points.
