Spatial linework of river fencing.

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)

The Department of Water and Environmental Regulation produces floodplain mapping of rivers and major watercourses and provides floodplain development advice to ensure that proposed floodplain development has adequate flood protection and does not impact on the existing flood regime of the area. This advice is related to major river flooding only. Other issues, such as stormwater drainage and environmental and ecological considerations are not addressed.

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. This dataset was formerly known as FPM Map Index (DOW-033)

This dataset is under review, please contact DWER for access to updated version. This dataset is a catalogue of current & historic boundaries of Water Allocation Plans and Statements and associated attributes. Each boundary indicates the area covered by the plan or statement. Water Allocation Plans may also be known as Water Management Plans. This dataset is intended to aid in water resource management.
