During its time, the dam passed through several hands. In 1939, it was sold to Briseis Consolidated NL of Derby, then in 1947 when they stopped operating; the Government purchased it and it was maintained by the Ringarooma Cascade Water Board until they were disbanded in 1985.
It was in 1985 that the Rivers and Water Supply Commission gained ownership, and as the dam storage had been empty since the 1970s they blasted a hole in the dam wall to let water pass freely through to the Cascade River.
The dam wall still stands today, and if you walk down to the river you can see where the holes were blasted to let the water run through. You can walk through the holes and to the other side which would have been full of water once upon a time. Now standing in the middle of the dam, with most of the vegetation grown back, the only thing to indicate that it was ever any different is the dam wall which still stands quite solidly in front of you. ;-)
