Spatial linework of river fencing. While the dataset has been prepared by the Department of Water, it contains information from State and federally funded foreshore assessment projects conducted at different times by Natural Resource Management groups with support from DOW regional offices. The Department of Water accepts no responsibility for collecting or updating this data but some known errors are being addressed. Foreshore Conditions - Fencing Linework (DOW-060)

Locations where an assessment of riverbank protection fencing has been undertaken and the exact spatial location of fences is unknown. The linework is based on river linework - it does not show the spatial location of fences. Selecting a point along the linework will indicate if there is a fence which protects the river bank and may indicate the condition of the fence. It should be noted that linework will appear where an assessment of riverbank protection fencing has been undertaken, even if no fence is present at that location. Left and right bank are relative to an observer facing downstream. This dataset was formerly known as Foreshore Conditions - Assessment of Right Bank Protection Fencing (DOW-047)

Special Areas dataset have been developed to incorporate a number of datasets. It is to be used in-conjunction with the Zones and Reserves. It contains Bush Forever Areas, Water Catchments, Environmental Conditions and Special Control Areas.

The dataset shows the location and spatial extent of aquatic ecosystems and their potential dependence on the surface expression of groundwater. It shows aquatic ecosystems at a scale of 1:100 000 and is best viewed at this scale. Not all ecosystems are present in the dataset, smaller aquatic ecosystems requiring a higher resolution are not displayed. Aquatic ecosystems that are known or likely to interact with groundwater in their hydrological cycle are potentially groundwater-dependent. The aquatic groundwater-dependent ecosystem (GDE) dataset shows the location of aquatic ecosystems and their GDE potential in the Fitzroy water planning area. The aquatic ecosystems included in the final dataset are categorised as: + Base-flow rivers + Wetlands + Estuarine and near shore marine + Springs. River base flow systems – River systems and associated riparian vegetation are unique ecosystems providing a habitat for threatened and priority flora and fauna, including native aquatic species and birds. Base flow is a component of the total stream flow that is supported by groundwater discharge. River permanence and flow duration indicate groundwater dependence during periods of low or no rainfall supporting differing ecosystem processes. There are several permanent riverine pools found on the main Fitzroy River channel. WETLANDS – wetlands that have a known or likely element of groundwater discharge in their hydrological cycle will be considered groundwater dependent. Wetlands are areas of seasonally, intermittently or permanently waterlogged or inundated land, whether natural or otherwise, such as lakes, swamps, pools, springs, and damplands. The hydrogeology of the Fitzroy water planning area is complex and variable. Hydrogeology mapping and a hydrogeologist should be consulted to determine the groundwater source of a wetland. ESTUARINE AND NEAR SHORE MARINE - Estuarine habitats are classified as components of an estuary, partially enclosed by land, with a continuous or intermittent connection to the ocean. With a freshwater influence from overland run-off, there is diluting and mixing of seawater. These habitats can include estuarine wetlands, lagoons, salt marshes, and mangroves. Near shore marine habitats are exposed to the waves and currents of the open ocean. Their water regimes are dominated by the ebb and flow of the ocean and tend to have a high salinity, normally greater than 33%. These habitats include seagrass meadows, coral, and stromatolites. The Fitzroy, May, Meda, and Robinson Rivers flow into the King Sound, supporting many different near shore marine habitats. Seagrass meadows, mangrove forests and salt flats are known to occur in and around the King Sound. SPRINGS - Springs provide a permanent source of freshwater and are recognised as important aquatic ecosystems found throughout the Australian landscape. The occurrence of permanent water in arid landscapes provides stable long-term habitat, critical to flora and fauna during dry periods, especially in the north-western region of Western Australia. A spring can be described as having a permanent discharge or flow of groundwater at the surface.

Environmentally Sensitive Areas as declared in Environmental Protection (Environmentally Sensitive Areas) Notice 2005, Government Gazette No. 55. This dataset is provided to assist landowners and managers in determining the location of environmentally sensitive areas under the Environmental Protection Act 1986. It is not a substitute for any requirement of the legislation. Those seeking further information should contact the data custodian.

Glossary: Annual exceedance probability (AEP) - the likelihood of occurrence of a flood of a given size or larger in any one year; usually expressed as a percentage. 1 in 100 AEP flood - this means that there is a 1 in 100 (or 1%) chance of a flow of this size or larger occurring in any one year. This flood has a 50% chance of being experienced at least once in a person's lifetime. The 1 in 100 AEP flood has been generally adopted in Australia and overseas as the basis for floodplain management planning. Floodplain - the portion of a river valley next to the river channel which is covered with water when the river overflows its banks during major river flows. The term also applies to land adjacent to estuaries which is subject to flooding. Australian Height Datum (AHD) - is a geodetic datum for altitude measurement in Australia. It was adopted in 1971 by the National Mapping Council as the datum to which all vertical control for mapping is to be referred. The datum is based on the mean sea level (1966-1968) being assigned the value 0.000m on the Australian Height Datum (AHD) at 30 tide gauges around the coast of the Australian continent.
