Cr Brian Corr said the Yellagonga Integrated Catchment Management Plan, a joint project of the cities of Joondalup and Wanneroo, was developed in 2009 and since then, the midge problem on the eastern side of the water had continued to worsen.
‘There are some plans to put some floating barges out there that will suck nutrients out but that could take years. In the mean time, the residents’ are plagued,’ he said.
Joondalup Mayor Troy Pickard agreed the midge problem from lakes Goollelal and Joondalup was ‘adversely impacting’ suburbs, particularly in Wanneroo.
He said while the Department of Parks and Wildlife was the lead agency, the City contributed more than $50,000 a year for a spraying program to help reduce the prevalence of midges.
He said the City has also addressed the flow of nutrients into the western portion of Yellagonga Regional Park and the City of Wanneroo had started a program to strip the nutrients captured by the road reserve before it enters the water ” the main cause of midges in the park.
‘It is a challenge and we will continue to do what we can to reduce the impact of midges but the reality is, we will never eliminate it and we will never defeat Mother Nature,’ he said.
The catchment management plan includes seven City of Joondalup projects, 11 City of Wanneroo and seven joint projects.
The cities are also receiving assistance from the Department of Parks and Wildlife, Friends of Yellagonga and Edith Cowan University.
