Plans to target source points of Hardy Inlet blooms
Released 18 Nov 2009
In announcing development of a Water Quality Improvement Plan for the Hardy Inlet as part of a wider plan for the Blackwood/Scott catchment, the department's district manager Dr Kath Lynch said the plan would be similar to those developed for the Vasse Wonnerup and Peel Harvey areas.
"A recent public forum in June on the condition of the Hardy Inlet held in Augusta presented new information on the causes of water quality decline in the lower Blackwood and Scott Rivers and the impacts on the overall condition of the Hardy Inlet," Dr Lynch said.
"Seasonally low oxygen in the Lower Blackwood from Alexander Bridge to Molloy Island and algal growth around Molloy Island were the main symptoms.
"These blooms, however large and annoying do not mean that the estuaries are dying.
"Our estuaries are however under stress from organic matter and nutrients from both rural and urban catchments.
"The long term solutions lie in reducing the supply of nutrients and organic matter from the catchments to the estuaries.
The Water Quality Improvement Plan model centres on consultation with and participation by local communities of the targeted waterways and catchment areas.
"These plans draw together all the available information on nutrient sources, pathways and consequences to the estuaries so that practical steps can be taken to improve the condition of the rivers and estuaries," Dr Lynch said.
A June 2009 community forum presented by the Ernest Hodgkin Trust kicked off the plan development.
"It is hoped that the Hardy Inlet Water Quality Improvement Plan will be completed by the end of 2010," Dr Lynch said.
This project is one of 15 around the state from an allocation of $5.4 million by the state government to further natural resource management.
