About Manor Lake
The primary purpose of Manor Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Mildred Osborn Merrick (private). It impounds the Tr-graves Creek near Sw Liberty.
The dam stands 80 feet tall and stretches 520 feet across, and has a maximum storage capacity of 2,008 acre-feet. Completed in 1967, 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.
At 80 feet, this dam is taller than 97% of all dams in the United States.
