Lake Crescent

Lake Crescent is a deep lake located entirely within Olympic National Park in Clallam County, Washington, United States, approximately 17 miles west of Port Angeles on U.S. Route 101 and nearby to the small community of Piedmont. At an official maximum depth of 624 feet it is officially the second deepest lake in Washington. A lake-wide bathymetric survey was performed from 2013 to 2014 by Eian Ray and Jeff Engea and 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 low levels of nitrogen in the water which inhibits the growth of algae. It is located in a popular recreational area that is home to several trails, including the Spruce Railroad Trail, Pyramid Mountain trail, and the Barnes Creek trail to Marymere Falls.
