Preservation plan for historic Leeuwin Waterwheel

The iconic Cape Leeuwin Waterwheel will be preserved under a revised management approach informed by new expert advice.

The Department of Biodiversity, Conservation and Attractions (DBCA) recently engaged former WA Museum specialist in historic artifacts, Ian MacLeod, to conduct a comprehensive review of the structure and provide key recommendations moving forward.

DBCA’s Blackwood District Parks and Visitor Services Coordinator Rory Chapple said previously, water was directed to the flume to help preserve the timber structure, however, Dr MacLeod’s recent assessment found that keeping the Waterwheel wet has actually accelerated timber decay.

“Paradoxically, keeping the Waterwheel wet has accelerated the deterioration of its timber components,” he said.

“By stopping the flow of water to the flume, we’re actually taking a crucial step toward long-term preservation of this valuable piece of WA’s heritage.”

Constructed to power a hydraulic ram that once supplied fresh water to the Cape Leeuwin Lighthouse and nearby keepers’ cottages, the Waterwheel is now a registered heritage site with the Department of Planning, Lands and Heritage.

“This is a win for both heritage and the environment. The important wetland habitat for the threatened Cape Leeuwin freshwater snail species will also be protected,” Mr Chapple said.

“By adjusting our approach, we’re not only ensuring the Waterwheel’s preservation, but also allowing the spring to recover in response to the region’s drying climate.”

Encrusted over time with limestone deposits, the Cape Leeuwin Waterwheel has become a symbolic feature of the region’s history and is much loved among visitors and locals alike.

DBCA will work with the Augusta Historical Society to implement key recommendations, which also include removing outdated infrastructure and applying preservation treatments to the timber and metal elements.
