A taskforce, made up of ACT government agencies, including Actew Corporation, the Commonwealth and surrounding NSW councils, found the lake's salvation would require of combination of water treatment, the reintroduction of macrophytes, culling of fish species, and a crackdown on sediment run-off.
Beneficial water plants, such as macrophytes, take up the same nutrients as the blue-green algae, reducing the severity and frequency of blooms, and help reduce turbidity.
Mr Rake said research showed that macrophytes beds could remove 95 to 99 per cent of faecal coliforms, 50 to 70 per cent of nitrogen, 60 to 80 per cent of phosphorous and 70 to 90 per cent of suspended solids.
''There's been a lot of research and discussion on how to improve water quality, our focus is now on actions, and what we can do.
