About
Williams Lake is a popular spot for fishing and swimming and a valuable wildlife habitat. With parts of the rock and concrete dam dating back to the 1700s, it is in poor condition and presents a safety issue. Repair work was carried out in 1977 and 1994 to address vandalism, but the dam was largely left in its original state. While there is no imminent risk of failure, the dam must be addressed before it gets to that stage.
The Province, through Build Nova Scotia, is investing $4.965 million to replace the aging dam. This will help ensure the safety of people living in the area, protect their properties, and the ecosystem.
The new dam will be built to environmental standards that will support protection of the lake’s ecosystem and regulate water levels for the enjoyment and safety of users and property owners. The work will be carried out between June and October over the next three years to limit the impact on aquatic life.
