Limestone Park was commissioned to design and build a 17 mega-litre dam at Moora. One of the challenges of this project was the client’s desire to obtain maximum volume within a given parameter. We had to use the extracted material from the middle of the dam to form the walls, but we could only excavate to 6 meters below dam crest height due to the underlying clays. This dam had to be constructed with very steep batters to achieve volume. We also had to “tie in” to an existing dam with a cascade, and also allow for an aeration unit to be constructed along one of the wall crests.
