alumy creek management

Clarence Valley Council is undertaking a survey of Alumy Creek landholders to determine how they would prefer the waterway to be managed.

Alumy Creek continues to be a challenging and complex waterway to manage due to the substantial modifications made to the creek, difficulties in controlling water hyacinth and the differing needs of local landholders.

The waterway has been highly modified to provide numerous functions such as flood protection, urban and agricultural drainage, water storage and to exclude river salinity for irrigation. Such modifications have benefited many members of the community however unintended adverse impacts have occurred including large aquatic weed infestations, degraded water quality, poor aesthetics and reduced biodiversity.

The aquatic weed Water hyacinth (Eichhornia crassipes) is a major problem as it covers up to 90% of Alumy Creek. It is recognised as the worlds worst aquatic weed as it damages assets; reduces biodiversity; increases water loss through transpiration; degrades water quality; reduces aesthetics; restricts commercial and recreational activities and is extremely difficult and costly to control.

Council is aiming for a sustainable long term reduction in aquatic weeds and an improvement in the health of Alumy Creek, while balancing the needs of the community.

Alumy Creek landholders have been provided with background information and three management options. The information that they provide in the survey will be used to update the Alumy Creek Management Plan which will take place by December 2009.
