Loch McNess and Lake Yonderup under the scientific drill
Released 27 Feb 2008
Scientists from the Department of Water will be at Yanchep National Park next month as part of an extensive study into Perth's key wetlands.
The scientists will use a small drilling rig to install groundwater monitoring bores that will be used to take water samples, check groundwater levels, and the quality of the ecologically significant local wetlands of Loch McNess and Lake Yonderup.
Department of Water Hydrogeologist and Project Manager, Dr Sandie McHugh, said earlier scientific investigations at the wetlands had caused a lot of public interest.
"We are keen to let people know that the environmentally sensitive machinery used will minimise the impact on vegetation and soil at all times.
"Loch McNess is an important turtle and waterbird habitat and highly valued by the local community for its social and ecological values.
"Lake Yonderup is under pressure from declining water levels and more information is needed to understand its unique hydrology."
Dr McHugh said the work at the park is part of a four year study which will provide the basis for the better management and protection of wetlands on the Gnangara and Jandakot mounds.
Other wetlands outside the area being studied include Lake Muckenburra, Tangletoe Swamp, Central Yeal Wetlands, Lake Bambun, Lake Bindiar, Timaru Wetland, Melaleuca Park, Melalecua Park Dampland, Lake Jandabup, Lexia Wetland and Wetland PM4.
"The new monitoring network will examine surface-water-groundwater interactions and assess the impact of declining water levels.
"It will help us reconstruct past water levels and tell us how the wetlands have evolved over time," Dr McHugh said.
"Several drill rigs will be used to complete the work, but with minimal disruption to local communities and the environment.
"We have consulted extensively with community and Indigenous groups to ensure cultural and environmental values intrinsic to the wetlands are protected and enhanced."
Once the work is completed the Department will monitor the bores each month.
