The Angas Catchment Dams dataset is a subset of the Hydro Water Bodies dataset and is limited geographically to the Angas River surface water catchment in South Australia. The data set contains polygon data outlining the physical extent of dams and estimated dam capacity (volume range in megalitres) and wall height information (in metres). Dam capacities have been estimated using various methods. These capacities have been converted to volume ranges. The majority of wall heights have been measured on site using a hand sight level. Dam capacity and wall height is based on available information and although best effort and care has been taken in compiling this information, accuracy cannot be guaranteed. The dataset will change over time as further information becomes available. This dataset provides a general indication of dam features within the Angas surface water catchment in South Australia. The dataset can be used for applications particularly in relation to water resource management and emergency planning and response. This dataset has been released for use in GovHack 2018 and will not be available after the competition weekend.

This dataset contains the digitised boundaries of all man made waterbodies (including farm dams) in southern Victoria and all larger man made waterbodies in northern Victoria using a combination of satellite and aerial imagery. Should be used in conjunction with FARM_DAMS_POINT. This data was updated in January 2019 to improve the usefulness of the attribute data.

This dataset representst Victoria’s Groundwater Management Areas (GMAs) Where groundwater has been intensively developed in Victoria, or has the potential to be developed, Groundwater Management Areas (GMAs) are established and the Permissible Consumptive Volume (PCV) is progressively set. Monitoring of the groundwater resource in these areas is undertaken by the Department of Sustainability and Environment through the State Groundwater Monitoring Network. Water levels and the amount of water allocated to groundwater users in the areas are closely monitored.

This dataset contains the digitised centroids of smaller man made waterbodies (including farm dams) in northern Victoria using a combination of satellite and aerial imagery. Should be used in conjunction with FARM_DAMS. This data was updated in January 2019 to improve the usefulness of the attribute data.
