Administration of the lake is governed by the Lakes Ordinance 1976. The NCA administers powerboats, moorings, major events, abstraction of water for irrigation, and various other matters associated with use of the lake.
The NCA concentrates on protecting the quality of the water and promoting greater and more diverse use of the lake. Lake Burley Griffin and Scrivener Dam are managed and maintained through service delivery contracts.
Water body, jetties, and other lake infrastructure are routinely cleaned and repaired to ensure safe use and function. The cleaning includes the removal of floating and submerged objects, and hazardous materials such as oil and grease. During the cleaning process care is taken for the protection of injured birds and animals.
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 levels are monitored weekly in the summer months and analysed and reported on in accordance with the ACT Guidelines for Recreational Water Quality [External Link] (ACT Health, 2010), weekly lake reports.
A licensing and charging scheme for the abstraction of water for irrigation was introduced on 1 July 2001. This is in accord with the reforms to water management in Australia under the 1994 Council of Australian Governments agreement.
The NCA also administers powerboats, moorings, major events and various other matters associated with use of the lake. For more information view the Lake Burley Griffin Recreational Policy.
The Authority's fish management program comprises of biennial monitoring of the fish population and the stocking of the lake with fish of selected species. The objective is to maintain a balanced ecosystem containing native predatory species such as Murray Cod and Golden Perch and a mixed recreational fishery. Over the years, the Authority has been stocking with different fish species.

Aquatic plants control program
Part of the lake maintenance includes monitoring of the growth of submerged and emergent aquatic plants. Aquatic plants, though serving an important role in the lake's ecology, can interfere with recreational activities. The Authority monitors and controls excessive plant growth in the lake.
Under this program, the excessive growth of the plants are controlled by harvesting materials from selected recreational areas such as Yarramundi rowing course, swimming areas, and boat launching areas and mooring areas. This is normally carried out in early summer months with the harvested weed removed to avoid impacting on water quality.
