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.

Winterfill sustainable diversion limit (SDL) volumes 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 shows for each 1611 Victorian SDL intermediate catchments: the diversion limit, the level of winterfill commitment as at 2014, and the volume of water available for new entitlements or trade. The catchments were originally developed in 2004. A major review in 2014 resulted in the addition of several additional catchments including the upper Snowy River, Phillip Island, French Island, and several new catchments in the Wimmera basin.
