Community groups and government agencies celebrate new opportunities following the installation of an AWMA Head and Discharge Gate.
The multi-leaf AWMA Head & Discharge gate allows for the regulation of water into Gol Gol Lake. The 494-hectare wetland located in southwest NSW was previously excluded from natural flows by an earthen levee bank built at the inlet to the lake.
The structure will allow future flood and environmental flow events to be better managed.
Peter Wilson, who has lived in the area for fifty years, says it will be much easier with the new regulator. “It means if we fill the wetlands or the lake, it can be regulated exactly, whereas in the past we dug a hole in the bank,“ he said. (ABC Rural)
The AWMA Head and Discharge Gate was selected as flows can pass over the upper leaf which results in much lower mortality rates for fish passing through the structure when compared to an undershot gate.
Troy Muster from the Lower Murray-Darling Catchment Management Authority says “The design and ease at which the regulator can be used now is far better for water management, with a design that allows for native fish to flow into the wetlands”. (ABC Rural)
The Gol Gol Lake regulator was constructed as part of the Lower Murray Darling Catchment Management Authority’s Gol Gol Lake Rehabilitation project. The works were funded by the NSW Government.
