Due to community concern over record algae levels and the clear observations of declining water quality, the Care Group have requested investigation and feedback on the decline. Clearly the community need to be updated on the worsening condition of LHM.
The recent rains have resulted in significant discolouration of water compared to previous Algal blooms. Even past rainfall events of over 500mm in one month have not resulted is such deterioration.
In particular the Care Group have asked as part of the investigation if Council could advise;
Were water tests taken of inflow from the canal during the rainfall events and if so;
Were the inflows a significant factor in water quality decline?
Phoslock was chosen for a whole lake trial by Griffith after very successful testing using actual water taken from depth at LHM. Despite extra Phosphorus added to the water during the tests, Phoslock was successful in removing all Phosphorus below detectable limits.
The results from the field trial were vastly different – no change in Phosphorus on the surface of the lake and minor change in levels at depth. It is important to note, that in Griffith Phoslock Trial Report, there we no reasons given for the lack of change in Phosphorus. Was it due to insufficient quantities applied?
Clearly the trial did NOT release the full potential of this product or the full potential to make a difference to the water quality of LHM.
Griffith have confirmed the benefits of Phoslock by recommending a further application with sand capping. With no action confirmed, an unknown time frame for implementation and the ongoing decline, the Care Group request that a top up of Phoslock at effective levels to bind the existing Phosphorus be done ASAP.
The latest algae results this week clearly eclipse all previous readings confirming observations of continual decline and the urgent need for action!
If you don’t want to see the lake in this horrible state for years, then you need to raise your concerns directly with GCCC.

The Care group have asked Candidates for a statement on their commitment to the restoration of LHM. It is important moving forward, that LHM has a Councillor that’s supports the community over the next 4 years to make this lake a priority!
I request that you review and share candidate statements in the Div12 electorate so the voters can make an informed decision when attending the polls on the 28th of March.
