Mason Lake

Mason Lake is a natural elongated lake south of Belfair, Washington, USA in Mason County. Named for Charles H. Mason, the first secretary of Washington Territory, the lake is on the isthmus of the Kitsap Peninsula between the Hood Canal and Pickering Passage of the Case Inlet. The smaller Benson Lake is to its eastern side. Mason Lake is approximately 1000 acres in size and four miles long. Its maximum depth is 90 feet and the mean depth is 48 feet. With 10.9 miles of Shoreline, the lake sits at 194 feet above sea level.

Originally a summer vacation community, the lake has always been known for its power boats, jet skis and water skiing. A county park provides swimming, picnic and boat launching access. The single lane boat launch is on the steeper side and winches tend to get jammed if they're in the locked or retrieval state.
