Chorus heralds arrival of Dock Lake water

WETLAND: A trickle of water is flowing into Dock Lake, south-east of Horsham. Wetland birds, frogs, insects and vegetation are the main beneficiaries of the bonus water.

WETLAND: A trickle of water is flowing into Dock Lake, south-east of Horsham. Wetland birds, frogs, insects and vegetation are the main beneficiaries of the bonus water.

Since the late 1990s Dock Lake near Horsham has been a silent, dry, grassy paddock.
But after a wet winter and a wet start to spring, a noisy chorus of frogs and waterbirds are heralding the arrival of water at the 215-hectare wetland downstream of Green Lake.
Wimmera Catchment Management Authority chief executive Dave Brennan said with Lake Wartook, Taylors Lake and Green Lake all full, water was being diverted into Dock Lake to prevent floodwaters inundating farm land.
He said it was only a small trickle and he did not envisage the lake filling. He said wetland birds, frogs, insects and vegetation would be the main beneficiaries of the bonus water.
“We are already seeing environmental benefits and will be monitoring the changes the water will bring,” he said.
“If there is additional spring rain we will see more water go into the lake, but for now there’s just a small amount.”
Last year Wimmera CMA undertook a study into Dock Lake which looked at its history and the environment. The study identified it as having a high environmental value wetland for native vegetation and waterbirds when it contained water.
District resident Russell Peucker said Dock Lake in the past had provided valuable bird habitat and was considered one of the best wetlands and bird sanctuaries in the Wimmera.
Historically, Dock Lake was a natural wetland that would fill and dry based on natural inflows before it became part of the Wimmera-Mallee headworks system.
With water storage changes as a result of the Wimmera-Mallee Pipeline, Dock Lake was removed from the headworks system in 2010.
