Yell out for Yellagonga

- Tyler Brown & Lucy Jarvis

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.

Visit joondalup.wa.gov.au or wanneroo.wa.gov.au to make submission­s before June 9.
