AWMA were engaged to supply water control gates and fish lock solution for Goulburn-Murray Water’s Box Creek Weir in Victoria.
Box Creek Weir acts as the flood outlet for Kow Swamp and provides releases to Box Creek, supplying water to the Torrumbarry Irrigation Area.
Four AWMA Combination Gates were incorporated into the new weir with eight stopboard frames for emergency isolation if required. The ‘Combination’ or ‘Split Leaf Gates’ (as referred to for this project) allow for both overshot and undershot flow management, as well as removal of both gate leaves from the waterway entirely during a flood event. The gates measuring 2.5m wide and 4.8m high are operated manually.
Sidewinding gates designed for the fish lock entry point are 4m high with a rack and pinion automated drive system to accommodate a 6.5m head pressure. The sidewinders are remotely monitored and controlled via G-MW’s SCADA system.
The fish lock exit gate utilises a DLF penstock with modulating cable drive system, designed to eliminate drive nut wear common in high frequency automated applications.
Isolating stopboards were also supplied for the fish lock, measuring 8m high. They are manually inserted and retrieved with a self-engaging AWMA Stopboard Lifting Frame.
The fish lock is protected with a fish friendly aluminium trash screen designed in accordance with USBR / AS5100 for debris loading.
