A Ballina Shire Council mayoral candidate wants to restore the health of Lake Ainsworth at Lennox Head as part of the development of a winter Olympic Training Facility.
Cr Keith Williams said if the Olympics facility was coming to Lake Ainsworth it needed to address some of the historical damage caused by the NSW Department of Sport and Recreation.
The plan consists of a number of Project funded by the Parties that have an interest in the Lake and the development of the Ski Jump Training facility at the Sport and Rec Camp. The plan involves:
Nutrient stripping of the Lake
Cr Williams said the Winter Olympics Training Development Project should pay for the cost of a large reed bed filtration system to gradually remove the build-up of phosphates and nitrates present in the lake waters.
‘The phosphate is a legacy of the former laundry at the Sport and Rec. camp that discharged high content phosphate laden waste water into the lake for several decades.
‘The nutrients haven’t gone anywhere and they are directly contributing the blue-green algae events we experience every summer.
Cr Williams said the reed bed must be located away from the body of the Lake (on Sport and Rec land) with the water pumped from and draining back to the lake.
‘Essentially a giant hydroponics systems, the harvesting of the reed bed (or any other vegetable grown in the system) gradually removes the nutrient harvesting. ‘There is an opportunity to discuss the design of the system with the local Aboriginal community through the Jali Land Council to identify if there is any particular plant species that could grown and economically utilised I some way.’
Retaining the Eastern Road and undergrounding Powerlines
Cr Williams said the State Government, through Sport and Rec. should pay for the re-alignment and rehabilitation of the Eastern Access Road and the under-grounding of the power lines that feed the Sport and Rec camp.
‘The road is not a legally made road and is effectively a driveway to Sport and Rec. The powerlines prevent the relocation of the road further east in some places and present difficulties with vegetation management.
‘Combining these two project at the expense of the beneficiaries of any development application granted for the Olympic training venue, in this case the State Government, is a reasonable contribution to make to the project.’
Eastern foreshore erosion
Cr Williams said the continued erosion off the Eastern foreshore was exacerbating the problems with the adjoining road and our ability to provide adequate riparian buffers around the lake foreshore.
‘Council should sell the unused road corridor through the caravan park and use the funds to upgrade the southern road and parking.
