About Lake Stellamaris

Lake Stellamaris is a dam in Leavenworth, Kansas. The dam is owned by Progress Inc (private). It impounds the Salt Creek near Leavenworth.

The dam stands 57 feet tall and stretches 900 feet across, creates a reservoir covering 48 acres, has a maximum storage capacity of 1,620 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1961, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 04/09/2021.

At 57 feet, this dam is taller than 95% of all dams in the United States.
