Cranberry Lake Dam, located within the Anacortes City Limits in Skagit County, Washington, is a vital structure designed for recreation purposes. Built in 1910, this earth dam stands at a height of 13 feet with a length of 380 feet, creating a storage capacity of 234 acre-feet. The dam is situated on Cranberry Creek and serves as a popular spot for outdoor activities such as fishing, boating, and wildlife observation.

Managed by the Washington Department of Ecology, Cranberry Lake Dam is classified as having a high hazard potential with a fair condition assessment. The dam's inspection frequency is set at every 5 years, with the last assessment conducted in August 2017. While the dam does not have an Emergency Action Plan (EAP) in place, it meets state regulatory requirements for permitting, inspection, and enforcement. With its stone core and soil foundation, the dam plays a crucial role in water resource management and flood control in the region.

Despite its age, Cranberry Lake Dam continues to provide valuable recreational opportunities while ensuring the safety and stability of the surrounding area. As climate change impacts water resources and weather patterns, the dam's role in managing water levels and protecting downstream communities becomes increasingly important. With ongoing monitoring and maintenance efforts, the dam remains a key asset in safeguarding the ecological and recreational value of Cranberry Creek for future generations.
