Nattai River Subcatchment
The subcatchment is mostly bushland reserved either in Nattai National Park, part of the Greater Blue Mountains World Heritage Area, or the Warragamba Special Area.
The Nattai River is a major tributary flowing into Lake Burragorang, the major reservoir for Sydney's water supply. 98% of the length of Nattai River has been classified as near intact, while the remainder is considered degraded due to the urban development in the headwaters at the town of Mittagong. The Mittagong STP discharges into Gibbergunyah Creek, a tributary of the Nattai River. Mittagong swimming pool, a small dam on the golf course and an historic low level weir, are in-stream structures that are affecting flows through the creek. |
