Drilling for answers to help protect Perth wetlands
Released 27 Feb 2008
The second stage of an extensive four year study conducted by the Department of Water into better managing groundwater and protecting wetlands on the Gnangara and Jandakot mounds has started.
From now until about June 2008, department staff will be installing groundwater monitoring bores at an additional thirteen ecologically significant wetlands.
The sites include Lake Muckenburra, Tangletoe Swamp, Central Yeal Wetlands, Lake Bambun, Lake Bindiar, Timaru Wetland, Lock McNess, Lake Yonderup, Melaleuca Park, Melalecua Park Dampland, Lake Jandabup, Lexia Wetland and Wetland PM4.
Department of Water's Hydrogeologist and Project Manager Sandie McHugh, said the new monitoring network would 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. The machinery will minimise the impact on vegetation and soil at all times.
"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."
