Catchment blueprints provide directions for natural resource activities and investment within each catchment. The purpose of catchment blueprints is to set targets for improved land management across all catchments. They will provide “focus and direction to individual and community initiatives, help coordinate government investment, such as extension work and grant funding, and contribute to the implementation of legislation such as the Native Vegetation Conservation Act 1997 and the Water Management Act, 2000” (DLWC 2001b). Draft catchment blueprints have been prepared for all Catchment Management Boards within the DRP. 142
16/08/02 Darling Riverine Plains Bioregion Background Report 8.3.4 Water Management Plans Water management committees, which include River Management Committees, have the responsibility of developing river flow regulations. Jurisdictions of water management committees vary, as some deal with regulated rivers and others deal with unregulated rivers and groundwater. Interim river flow objectives have been developed for all catchments within the DRP and river management committees use these objectives in preparing the flow regulations for their management plans (EPA 2000). Environmental flows aim to restore, to some degree, natural flows within each catchment. River flow regulations differ from catchment to catchment and include various combinations of the following criteria (EPA 2000): “off-allocation access rules - restrictions on extraction of naturally occurring high flows; transparent dam rules - releases from water storages are matched to inflows (usually confined to relatively small inflows); translucent dam rules - a percentage of inflows to the dam must be released (usually confined to periods outside the irrigation season); contingency allowances - a bank of water reserved in the dam and released for specific environmental purposes (such as flushing algal blooms or providing water to complete fish or waterbird breeding); end of system flows - releases to ensure that the river provides water for downstream waterways (beyond the end of the river); and diversion thresholds - these require extractions to be reduced or to cease when flows are below a defined level.” River Management Committees for all major regulated rivers and the Barwon-Darling River developed flow rules in 1999 for 1999-2000 (EPA 2000) (Table 8.6).
