Yell out for Yellagonga
REDUCING water pollution from households and businesses is part of a plan to protect wetlands in Yellagonga Regional Park.
The cities of Joondalup and Wanneroo have invited feedback on the draft Yellagonga Integrated Catchment Management Plan 2021-26 until June 9 following council approval in April.
The five-year plan includes updated projects that aim to improve the conservation value of the park and health of its wetlands, including Lake Joondalup, Beenyup Swamp, Walluburnup Swamp and Lake Goollelal.
Joint projects include monitoring water quality, water conservation, midge research and local biodiversity.
Both cities have projects involving ecotourism or community awareness, stormwater management and conservation maintenance.
Wanneroo’s projects also cover contaminated sites, particularly in Wangara, and planning frameworks, including for urban development in east Wanneroo, which could lead to higher groundwater levels.
The plan said Yellagonga’s surface water catchment area covered about 4000ha, including residential, commercial and light industrial areas.
“Urbanisation has resulted in increased surface water run-off through drainage networks, bringing with it polluted water,” it said.
The plan said run-off could be vital for wetlands given reduced rainfall levels, but ecology required it to be uncontaminated water.
“Pollutants and contaminants enter the park’s wetlands via stormwater run-off, groundwater flow, and, to a lesser extent, rainfall,” it said.
The plan said both cities had been upgrading stormwater drains and sumps to reduce contamination.
Wanneroo has also been inspecting automotive industry premises in Wangara to educate businesses about the impact drain pollution had on wetlands.
