This project involved the design and installation of an innovative fish lift system.
Partnered Sydney Catchment Authority and Leighton Contractors.
The 43m high Tallowa Dam is an integral part of the Sydney Catchment Authority’s Shoalhaven Scheme and is essential to the bulk raw water supply system for Greater Sydney.
Project accolades include Australian Institute of Project Management NSW Chapter Excellence Award in the Sustainable Projects category.
AWMA was required to develop a number of unique flow control structures for the dam and fish way.
Control structures included a positive cable drive on an 8m high overshot gate on the surface water draw off chamber.
A hydraulically actuated spillway gate was cut into the existing dam crest, and a segmented gate was installed for the fish way entrance.
