Water engineering specialists Spiire performed the analysis, which reviewed aspects of the lake including survey work and landscaping opportunities.
The results included retaining a portion of the lake for ornamental and recreational purposes, using integrated water management for water treatment and incorporating wetlands into the design.
Results also included a stormwater management solution as Numurkah develops towards the north.
Moira Shire mayor Libro Mustica said many community members wanted the lake full year-round, but this would require council to purchase additional water.
He explained this could place council in direct competition with farmers for water.
“Water is now tradeable with both temporary and permanent markets operating,” he said.
“What this means is that in some seasons water has a higher value on the market to some water owners than its perceived value as water used for irrigation or recreational purposes.”
He urged interested parties, including residents, visitors and interested businesses, to voice their input on the possible improvement opportunities.
The lake has experienced numerous issues as a result of recent low water levels including reduced amenity, low water quality, E-coli concentrations, vegetation that limits recreation and reduced recreational value.
Low levels also reduced fish habitat, which resulted in council paying for the removal of 60 native fish into nearby Broken Creek in 2019.
The lake was constructed in the 1970s by a private developer and was supported by the then Numurkah Shire.
The majority of the lake is still owned by a private company.
