Honeymoon Lake Dam, located in Washington State, was completed in 1969 and serves primarily for recreational purposes. This private-owned earth dam stands at a hydraulic height of 22 feet and a structural height of 19 feet, providing storage of up to 54 acre-feet of water. The dam is situated on Tr-Honeymoon Bay and is regulated by the Washington Department of Ecology, with inspections conducted every 5 years to ensure its fair condition.

Despite its relatively small surface area of 7 acres, Honeymoon Lake Dam poses a high hazard potential due to its location and the surrounding drainage area of 1.84 square miles. The dam's emergency action plan was last revised in July 2021, reflecting the ongoing efforts to maintain the safety and integrity of the structure. With Congressman Rick Larsen representing the area in Congressional District 02, Washington, stakeholders and enthusiasts in water resource management and climate resilience should keep an eye on developments related to Honeymoon Lake Dam to ensure the continued sustainability of this recreational asset.
