At the Canberra site, overland flow is collected in natural channels, some of which have been diverted or piped for short sections to accommodate localised site development. These channels feed into Sullivans Creek and thence into Lake Burley Griffin. Run-off from buildings is fed into the town storm-water system. At the Jervis Bay site, overland flow runs into Lake Mackenzie.

Management prescriptions


The objective is to collect and dispose of storm water in such a way as to minimise pollution of downstream water or facilities.


At the Canberra site, existing natural channels will be maintained and planning for drainage of storm water will be incorporated in any new developments. At the Jervis Bay site, advice about minimising the potential for pollution of Lake Mackenzie will be sought and this aspect of drainage will be examined in the development planning guide.
