After 8 long months of closure finally some positive news!
Toxic levels have decreased below the trigger level for closure but the lake will remain closed until several good water quality samples are received. It is important to not enter the lake until the Lake Closed signs are removed.

It is also important that you do not enter the water where surface blooms are present. These blooms are the concentration of highly toxic algae gathered over hundreds of meters of surface water by prevailing wind conditions.
Council are in the process of updating water quality trends and other information on the councils website which can be found below;
Residents and Users “Still in the Dark” with no Water Quality Updates.
Recently the lake has shown some signs of recovery with improvement in water clarity as we move out of Winter. This has been the normal pattern before the re-growth of algae clouds the water. With the swimming season about to commence, users and user groups want the be kept informed on water quality and the possibility of the lake opening.
Despite requests for open and transparent communication with Council and numerous requests for 3 monthly water quality updates, to date none have been made available or even a timeframe.
The Care Group will again request updates on the last water quality results since the last update in May.
With the lake in poor condition, it is now more important than ever to minimise impact on water quality.

LHM Newsletter Winter 2018
The LHM Care Group have raised concern with the GCCC over the delay in the Short Term Option Report that was due in June. The report is to look at the feasibility of short term options to improve the resilience of the lake to future algal blooms.
With no water quality updates for nearly 3 months and the algal blooms continuing through winter, residents and users are speculating that the lake may not even open this Spring/Summer!
A great deal of hope is being placed on the possible implementation of these options and timing is critical. Any treatment needs to be in place before the algae starts multiplying in the warmer months.
GCC Council advises the delay is due to the complexities of the lab work, with the Griffith Uni Report being available to Council Shortly.
Council are striving to meet the action plan timeline and are prioritising finding a solution to the current state of the algal bloom.
The Long Term Options Report is still scheduled for September.
Despite progressing well into winter with cooler water conditions far from ideal for Algal growth, the lake still remains closed. With the last water quality update 2 months ago, the Care Group have requested regular updates every 3 months to keep the public informed on current conditions and any improvements.
Council have advised they are working towards providing regular water quality trends in the near future that will be updated on the Councils Lake Hugh Muntz Webpage
Winter/early spring is normally the time the lake “gasps for air” from the ongoing Algal blooms but the current brown, cloudy water conditions are not promising.
The Short term Options Report from Griffith Algae Experts due shortly may offer some hope for improving conditions.
The Care Group, Council Representatives and Griffith Algae experts met on the 1st of June to discuss options for restoration including;
This was a general discussion with no specifics relating to LHM due to options still being investigated.
The Lake Hugh Muntz Action Plan Timeline was released indicating proposed timelines for investigation and possible implementation of solutions. Please see the link below for more info.
Link: LHM Action Plan Timeline.
A brief summary of points below;
- Paul Taylor pushing for approval of the initial 100k funds at Council Budget Meeting.(funding not yet approved)
- Full 100k to be spent on improvements.
- No clear short term options indicated, but will be considered before the swimming season. Therefore, no clear indication on if and when the lake will be open to swimming at this stage.
- Short term solutions ideally implemented before increased Algal growth heading into summer.
- Vacuum removal of current floating algal blooms along shoreline is being investigated but difficulty with filtering the algae.
- Council health dept indicate no current health risks from airborne contaminants from Algal blooms.
- Long term options still being investigated. Griffith Experts running lab tests on various lake samples with several possible solutions. Long term Options Report due in September.
- Investigation of improved water quality monitoring with possible live recording devices.
- Visibility and ongoing, regular updates to the public on water quality results with meaningful summary.
- Care Group requests involvement in the Revised Lake Hugh Muntz Management plan in September.
- Meeting with Key users and groups to discuss options recommended by Griffith Experts.
Care group representatives will be meeting with Griffith Uni Algae experts and Council on Friday 1st of June.
The meeting is a great opportunity to raise User and Resident concerns and seek clarification on issues/difficulties and the best way forward.
To get the most out of the meeting, the Care Group have produced a Draft Management Plan suggestions for discussion and some sample questions below for the algae experts.

Council has just distributed a newsletter to residents advising on the current poor condition of Lake Hugh Muntz and progress on improving the situation. The graphs indicate that current toxic levels of Algae in LHM are STILL high. The deterioration and severity of the outbreak is clearly evident around the lake. The ongoing Algal surface blooms appearing around the lake have residents and users continually asking “Why has LHM been left to deteriorate to this horrible condition”

Lake Rescue Will Save Nippers From Sharks
Inquiries were made today with Council on recent trends in water quality relating to the ongoing Algal bloom. The last results received in Councils Newsletter to residents below indicate a downward trend. Unfortunately the algae results have remained above the red closure level in all sites measured. The lake will continue to be closed in the foreseeable future.
