Lake Youngs

Lake Youngs is a large reservoir in Washington located between Maple Valley and Renton, covering about 700 acres. The water reaches depths of up to 72 feet and flows through a pipeline network that carries water from the Cedar River to Seattle.

The reservoir was constructed in the 1920s with work completed in 1926, replacing the earlier Swan Lake that covered about 548 acres. Dams at the south and east ends raised the water level and expanded storage capacity for the city's water needs.

The lake is named after L. B. Youngs, a longtime leader of Seattle's water department who passed away in 1923. The name reflects his role in shaping the city's water supply system.

The reservoir is not open for recreational activities such as swimming or boating since it is part of the city's water supply infrastructure. Visitors should stay on designated paths and respect the signs that remind people to protect the water system.

Aircraft pilots flying to and from Renton Municipal Airport use the lake as a visual landmark to help them navigate. This practical application shows how important the water body is beyond its role in water supply.
