Description 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.
Dataset Use 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.

Data Quality

Lineage Features were originally captured by analog photogrammetric techniques based on 1:80 000 scale aerial photography and surveyed ground control for the standard 1:50 000 mapping program. The photogrammetric plot detail was hand traced onto stable film for map production. The reproduction material was subsequently scanned, the data vectorised and processed through standard procedures to clean,and code the data. The tile based data was processed, edge-matched and converted to GIS format. Subsequently, features have been maintained by heads-up-digitising techniques within geographic regions determined by project requirements. Since the year 2000, update changes generally have not been verified in the field. Through the Commonwealth (Bureau of Meteorology) funded Australian Hydrological Geospatial Fabric (Geofabric) project 2011-2012 respective versions of surface water datasets from the former DFW and former DENR were integrated to create a single authoratative database. Water bodies within Adelaide & Mount Lofty Ranges (Fleurieu Peninsula), Kangaroo Island and Northern & Yorke NRM regions were updated to a detailed survey specification. Subsequently, water bodies within the remaining area of A&MLR and the western part of the SA Murray-Darling Basin (Eastern Mount Lofty Ranges) regions were also updated to the detailed survey specification. Data in the pastoral regions of the State has been sourced from the Bureau of Meteorology (BoM) Geofabric Surface Cartography V2.1 AHGFWaterbody dataset (equivalent to Geoscience Australia's GEODATA TOPO 250K). The Geofabric data was integrated in June 2013. Volume and wall height information has been compiled from a range of Departmental datasets. This information has been joined to the Angas Catchment Dam dataset using unique source identification numbers. Volume figures have been generalised INTO categories 0-2, 2-5, 5-10, 10-20, 20-50 and >50ML for the purpose of the GovHack exercise.
Completeness Features in this dataset are complete over the geographic extent of the Angas surface water catchment.
Positional Accuracy Features sourced from the BoM Geofabric are generally within +/- 100 metres of their true position. Of the remaining data, 90% of well defined features are within +/- 25metres of their true position. Features captured or revised to the detailed survey specification are within +/- 12metres of their true position.
