Bargo River Subcatchment
This is the smallest subcatchment (130 square kilometres) in the Hawkesbury Nepean catchment.
It contains two reaches separated by the Bargo reservoir. The upper reaches are considered to be in near intact condition, while below the resorvoir, the river is experiencing some degradation from mining activity impacts and damaging access to the riparian zone. Picton Weir upstream is also having a negative effect on this reach. There are no reserved lands in the subcatchment.
Land use pressures such as effluent ponds, intensive farming, service stations and mining activities pose possible threats to the health of the waterways. Much of the subcatchment is bushland, with some rural and peri-urban developments near the Bargo township. Increased frequency of bushfire and impacts of residential development impact on river health as well. The Bargo subcatchment is largely undisturbed and its gullies and gorges are among the steepest in NSW. A significant plant species (Persoonia bargoensis) has been identified in the Bargo subcatchment and is restricted to this area. The Bargo River also supports an Endangered Ecological Community (Sydney Turpentine Ironbark Forest). Some of the community based environmental activities include a Privet Removal Project on Myrtle Creek and the activities of the Tahmoor Park Landcare Group |
