Youngs Lake Outlet Dam, also known as South Dam, is a vital structure owned by the local government in Auburn, Washington. Built in 1921, this earth dam on Little Soos Creek stands at a height of 30 feet with a hydraulic height of 33 feet, serving primarily for water supply purposes. With a storage capacity of 35,450 acre-feet and a drainage area of 2.19 square miles, the dam has a significant impact on the surrounding environment.

The dam's condition assessment in June 2019 deemed it satisfactory, but its hazard potential is classified as high. The last inspection highlighted its structural integrity, with an inspection frequency of 5 years. The emergency action plan (EAP) for the dam was last revised in December 2020, ensuring preparedness in case of any unforeseen events. The location in King County, Washington, and the close proximity to the Seattle District underline the importance of this dam in the region's water resource management and climate resilience efforts.

Youngs Lake Outlet Dam plays a crucial role in the water supply infrastructure of Auburn, Washington, ensuring a reliable source of water for the community. Its historical significance, combined with its high hazard potential, emphasizes the need for regular inspections and maintenance to uphold its structural integrity and safeguard against potential risks.
