The Goolwa Barrage is located in South Australia, near where the River Murray completes its 2,530km journey.
The Barrage was constructed in 1940, to restrict salt water ingress into the river during tidal events, as well as maintaining water levels in the lower lakes.
The Goolwa Barrage is approximately 632m long, up to 7m deep, and contains a 30.5m by 6.1m lock chamber.
AWMA were engaged to custom design a water control gate to be retrofitted within the existing drop board guides on the Barrage.
The downwards opening DLF gate is hydraulically actuated, allowing easy and safe management of flows, to control water levels, water quality and environmental outcomes.
Design features include sacrificial anodes, dual hydraulic cylinders and a solar powered hydraulic power pack.
