Based on the latest information available, the Mirror Lake boat launch in New Hampshire is a concrete boat ramp that is 12 feet wide. It services Mirror Lake, which is a relatively small body of water with a surface area of approximately 377 acres. The boat launch is located on the southern end of the lake, near the town of Tuftonboro.

According to the New Hampshire Fish and Game Department, Mirror Lake is open to a variety of watercraft, including motorboats, canoes, kayaks, and sailboats. However, there are certain restrictions in place to protect the lake's natural resources. For example, there is a 10 horsepower limit on motorboats, and wake boats and personal watercraft are prohibited.

In terms of facilities, the Mirror Lake boat launch has a small parking lot that can accommodate approximately 10 vehicles and trailers. There is also a portable restroom available on site. While the boat launch is open year-round, it is important to note that the lake may be subject to ice cover during the winter months, and boaters should exercise caution when using the launch during this time.
