sec.19 Water plan outcomes—environmental

The environmental outcomes for this plan area are— to maintain, and if possible improve, flows of water to which this plan applies that support— native plants and animals, and their freshwater and estuarine habitats; and long-term water quality suitable for riverine and estuarine ecosystems; and to maintain, and if possible improve, the low flow regimes, of the watercourses to which this plan applies, that support ecological assets, for example— riffle habitats; and the quality and persistence of waterholes; and the connectivity of watercourses required over the lifespan of native aquatic species, including to allow for opportunities for movement, spawning and recruitment of the species; and to maintain the medium flow regimes and high flow regimes, of the watercourses to which this plan applies, that support ecological assets, for example— river-forming processes; and riparian systems and their functions; and floodplain and wetland ecosystems; and estuarine ecosystems; and to maintain, and if possible, improve, flows of freshwater to which this plan applies that support ecological processes in the following waters— waters of estuaries that receive flows of water from the plan area; the marine waters of the Great Barrier Reef; the waters of the Great Sandy Strait declared Ramsar wetland; and to minimise adverse environmental impacts, relating to water to which this plan applies, caused by the operation of infrastructure in the plan area; and degradation of water quality, a reduction in habitats for the Mooloolah River, the Noosa River, the Maroochy River and their tributaries—to minimise change to the natural flow regime that supports the rivers and tributaries; and for the freshwater reaches of the Mary River and its tributaries—to maintain, and if possible, improve— the low flow regime of the freshwater reaches; and the flow-related habitat requirements of ecological assets in the freshwater reaches; and Mary River cod, Australian lungfish, Mary River turtle, white-throated snapping turtle for the Burrum River and its tributaries, downstream of Lenthalls Dam—to support freshwater flows that are necessary— for estuarine processes; and to reduce hypersaline conditions in the upper Burrum River estuary; and for the underground water management area—to maintain, and if possible improve, the availability and quality of underground water to which this plan applies to support ecosystems dependent on the underground water. wetlands terrestrial vegetation communities ecosystems of which Searys Creek or Teewah Creek form a part ecosystems of which springs form a part In this section— ecological assets include a species, a group of species, a biological function, an ecosystem and a place of natural value that is dependent on attributes of a flow regime to support the asset’s long-term viability. flow regime means the entire range of flows at a point in a watercourse including variations in the watercourse height, discharge, seasonality, annual variability and event duration. flow-related habitat requirements , of an ecological asset, means the hydraulic or physical attributes of a flow regime that are required— for a particular biological process or response to happen in relation to the asset; or to maintain the long-term biological integrity of the asset. movement opportunities of species or groups of species freshwater reaches , of the Mary River and its tributaries, means— the Mary River and its tributaries, upstream of the Mary River Barrage; and Tinana Creek, upstream of Tinana Barrage.
