The dam and reservoir is overseen by TransAlta and, by contract, will continue in their oversight role after the coal plant is closed at the end of 2025. At that time, water rights will revert to the city of Centralia for public consumption. A 2022 study to remove
18-521: Is an earthen bank structure measuring 190 feet (57.9 m) tall and spans 1,340 feet (408.4 m). With low water levels in the reservoir, the system provides some flood protection to communities downstream, such as Bucoda , however, the dam was not built for flood prevention.

The study concluded the best options were improvements to the dam to include fish passages, as well as to use the dam for flood control purposes. In June 2024, a petition to remove the dam at the termination of
