😈My visit was on May 17 2017, a rainy bleak day!
The Rowville East-West Firebreak is next to the western perimeter fence, starting at Army Rd, reached from a gate at the end of Bergin's Rd. Adjacent to it, on private property, is the old Retarding Dam, which was part of the Belgrave to Dandenong Pipe, connected from the larger Dam just to the north.
The pipe system was opened in 1899 and was decommissioned in 1950.
When the Pipe closed down, the Dam was used as a public swimming facility, until 1955, known as Heany Park Lake. The large Dam is now in private property owned by Scouts Victoria and public access is prohibited.
The small Dam contains run-off water, rubbishj and weeds - remains of the wooden platform exist at the western end, which was associated with the outlet pipe.
