The waterfall and surrounding pathways are expected to open during the week of June 29.

Friends of Mrs York's Garden spokesperson Dianne Davison said works have taken longer than expected due to recent wet weather and the nature of the site.

"We are progressing now and getting it finished off. At this stage we would expect the walkway to open early next week (June 29)," she said.

"We have had help from the Maritime Museum particularly to set up the solar panel for the water pump.

The original waterfall and windmill were the final wishes of Mrs Bertha York, who began the floral reserve in 1961 and saw their completion in 1970.

She would pass away in March 1971, leaving the care of the garden to council.

"This waterfall was the last request of Bertha before she passed away and it was a fairly special request from her. There was a public community appeal for funds to create the windmill and stone seats in the garden," said Mrs Davison.

"The waterfall was completed and opened around December 6, 1970 and Bertha passed away in March, 1971. It's special we can bring that back to the garden.

"The spillway will remain from the original waterfall to be reused with the original concrete tank and a stone bench."

The $50,000 project has been supported by Friends of Mrs York's Garden community fundraising as well as the dedicated commitment of residents Bob and Evelyne Lynch.

The works are being completed by BNJ Landscaping with assistance from garden volunteers.
