About Ski Roundtop
The primary purpose of Ski Roundtop is grade stabilization. Grade stabilization dams prevent erosion by reducing the slope and velocity of water flowing through a channel. They're commonly used to stop gullies from deepening and to protect downstream land and infrastructure. The dam is owned by Ski Roundtop Operating Corp. (private). It impounds the Beaver Creek.
The dam stands 20 feet tall and stretches 510 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 48 acre-feet, and collects water from a drainage area of 1 square miles.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. The most recent inspection on record was 03/10/2021.
