Surface Water sustainable diversion limit (SDL) Resource Units (Murray-Darling Basin)

The surface water sustainable diversion limit (SDL) resource unit dataset defines the boundary of 29 surface water SDL areas in the Basin Plan 2012.The SDLs represent the maximum long-term average quantities of water that can be taken for consumption in any one year, i.e. the long-term average annual limit. An SDL will be set for all diversions in each of the 29 surface-water SDL areas that have been established for the Basin Plan. Some areas have been excluded from Basin water resources by regulation. https://data.gov.au/data/dataset/surface-water-sdl-resource-units本数据集为地表水可持续取水限额（surface water sustainable diversion limit, SDL）资源单元数据集，界定了2012年流域计划（Basin Plan 2012）中划定的29个地表水SDL管控区域的边界。SDL指任意年度内可用于消耗性取水的长期平均最大水量，即长期年度平均取水限额。针对为实施2012年流域计划而设立的全部29个地表水SDL管控区域内的所有取水工程，均会设定对应的SDL。部分区域已通过法规被排除在流域水资源管理范畴之外。数据来源：https://data.gov.au/data/dataset/surface-water-sdl-resource-units
