About Swantner Lake Dam
The primary purpose of Swantner Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Albert & Jane Swantner (private). It impounds the Tr To Calvey Cr near Pacific.
The dam stands 32 feet tall, creates a reservoir covering 8 acres, has a maximum storage capacity of 137 acre-feet, and collects water from a drainage area of 32 square miles. Completed in 1969, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream.
At 32 feet, this dam is taller than 76% of dams nationwide.
