Administration of Lake Burley Griffin (the Lake) is governed by the Australian Capital Territory National Land (Lakes) Ordinance 2022. The National Capital Authority (NCA) administers powerboats, moorings, major events, and various other matters associated with use of the Lake. For more information view the Lake Burley Griffin User Guide and Lake Burley Griffin Safety Guidelines.
The NCA protects the quality of the water and promotes use of the Lake.
The water body, jetties, and other Lake infrastructure are routinely cleaned and repaired to ensure safe use and function as well as the removal of floating and submerged objects and rubbish.
The environmental state of the Lake is monitored through physical, chemical, and biological testing of the Lake water. These parameters are measured across the Lake and analysed to identify any change and, if required, appropriate management responses are proposed. Bacterial and algal levels are monitored weekly, year-round. The water is analysed and reported on in accordance with the ACT Guidelines for Recreational Water Quality (ACT Health, 2014). The Lake Burley Griffin Water Quality Updates are available on the NCA website, www.theswimguide.org or through the free Swim Guide App.
Fish management
The native fish population in Lake Burley Griffin is enhanced through the regular seeding of fingerlings. Species such as Murray Cod and Golden Perch are released on an alternate basis to maintain a mixed recreational fishery. Read The Lake Burley Griffin Fish Survey 2023-24.
Aquatic plants control program
Part of the Lake maintenance includes monitoring the growth of submerged and emergent aquatic plants (macrophytes). Aquatic plants, though serving an important role in the Lake's ecology, can interfere with recreational activities. The NCA monitors and controls excessive plant growth in the Lake.
