Loon Lake is a 294-acre (119 ha)[1] lake located in Douglas County in the Oregon Coast Range of the United States,15 miles (24 km) east-southeast of Reedsport, Oregon at an elevation of 392 feet (119 m).[2]. The lake is about two miles (3 km) long with a maximum width of about 0.4 mile (0.6 km), and is over 100 feet (30 m) deep in some places.
The lake is "a classic example of a landslide lake"[1], dammed by a slide of sandstone blocks which fell into the Lake Creek valley about 1400 years ago. The lake was discovered in 1852 and named for the loons found on its waters.
