History
Beaver Lake / Trossachs Barricades
In the 1970s, East and West Beaver Lake Dr. SE were connected to improve emergency access. Now, the low-traffic road is popular with hikers, joggers, and cyclists.
Geology of Beaver Lake
Beaver Lake formed from glacial activity 20,000 years ago, with ice sheets carving the landscape. Retreated ice left behind depressions that filled with water, creating Kettle Lakes such as ours.
Early History of Beaver Lake
Beaver Lake was known to the Snoqualmie Tribe and later to loggers in the 1920s. It was developed first with logging, and later with resorts, and community events, becoming a small community by the 1960s.
Recent History of Beaver Lake
In the 1970s, Beaver Lake's community grew rapidly with new developments, water access, and public services. The City of Sammamish was incorporated in 1999 to manage growth and preserve green spaces.
