Lake Crescent

Lake Crescent is a deep lake located entirely within Olympic National Park in Clallam County, Washington, United States, approximately west of Port Angeles, Washington on U.S. Route 101 and nearby to the small community of Piedmont. At an official maximum depth of, also the maximum depth of the depth sounder used to find that depth (see depth section), it is officially the second deepest lake in Washington. Unofficial depth measurements of more than have been rumored in the region for years, although this figure has recently been proven false after a lake-wide bathymetric survey was performed from 2013 to 2014 by Eian Ray and Jeff Enge. The results of this survey showed the maximum depth as being 596 feet. Using GIS statistical analysis, this survey also showed the lake contains approximately 0.5 cubic miles of fresh water.Lake Crescent is known for its brilliant blue waters and exceptional clarity, caused by a lack of nitrogen in the water which inhibits the growth of algae. It is located in a popular recreational area which is home to a number of trails, including the Spruce Railroad Trail, Pyramid Mountain trail, and the Barnes Creek trail to Marymere Falls. The Spruce Railroad Trail follows the grade of what was once the tracks of a logging railroad along the shores of the lake. Following this trail on the north side of the lake, one can find the entrance to an old railroad tunnel as well as "Devils Punch Bowl", a popular swimming and diving area.
