Lake Sammamish

Lake Sammamish (map) is the sixth largest lake in Washington, and one of the major recreational lakes—with high use by fishermen, boaters, water skiers, swimmers, and picnickers. The freshwater lake is 7 miles long and 1.5 miles wide, with a maximum depth of 105 feet and a surface area of 8 square miles. It lies east of Bellevue and west of the Sammamish Plateau, and stretches from Issaquah in the south to Redmond in the north. There are popular State and County parks along the shore including Marymoor Park at the lake’s north end, Lake Sammamish State Park at its south end and East Lake Sammamish Trail. Marymoor Park’s 640 acres include biking and walking trails, sports fields, rock climbing, a dog park, a radio control aircraft flying field, and a velodrome. Lake Sammamish State Park boasts 6,858 feet of waterfront along its 512 acres. The parks day-use facilities including an active boat launch, picnic tables and shelters, playgrounds, two swimming beaches, and softball and soccer fields.

Lake Sammamish is uniquely sited within four cities (Bellevue, Issaquah, Redmond and Sammamish) and unincorporated King County (see map).
