Victorian winterfill sustainable diversion limits

Winterfill sustainable diversion limit volumes (SDLs) have been developed across Victoria and represent the upper limit on winterfill diversions, beyond which there is an unacceptable risk that additional extractions may degrade the environment. Combined with the volume of current extractions the SDL provides water managers with a volume of available water in catchments across Victoria. This dataset includes the 1611 intermediate catchments that cover the state. Data associated with each intermediate catchment is held in the SDL_DATA layer.

维多利亚州已制定冬季蓄水可持续取水量限值（SDLs），该限值代表冬季蓄水取水的上限，超过此上限，额外取水可能会对环境造成不可接受的退化风险。SDL与当前取水量相结合，为维多利亚州各流域的水资源管理者提供了可用水量数据。本数据集包含覆盖该州的1611个中间流域，每个中间流域的相关数据存储于SDL_DATA图层中。
