Set an end of system flow target (equivalent to the bottom of baseflow) in regulated valleys (Gwydir, Namoi and Border Rivers) to protect baseflows to enable baseflow targets in the Barwon-Darling to be achieved in non-dry times. The end of system flow achieved through limitations on supplementary and floodplain harvesting access in the first instance and releasing a proportion of daily inflows to the dams(s) in each valley to meet the end of system flow target. This approach only makes releases each day if there is sufficient inflow to the storages over the preceding 24 hours and does not require reserves to be set aside. Releases not made in periods where the rolling 30-day average dam inflows fall below the 75th percentile (the dry inflow trigger). The Panel has not included a recommendation for an end of system flow rule for the regulated Macquarie-Cudgegong as the end of the system flows discharge into the Macquarie Marshes.

The Panel recommended that the Gwydir, Namoi and NSW Border Rivers regulated water sharing plans should include a ‘connectivity’ environmental water allowance (EWA) to provide pulses as needed for water quality and other environmental outcomes during dry times. Replenishment releases triggered by the dam inflows falling below the 75th percentile on average over 30 days. Up to two large replenishment releases of 20 GL made each year in each valley triggered by low inflows into storage dams. Release triggered on 31 October and 28 February each year if the inflows to the valley storage dams are less than the 75th percentile. Releases are made to achieve at least a week of flows at Bourke with peak flows above 972 ML/d for up to 10 days and at least 30 GL total event volume. A connectivity environmental water allowance was not considered for the regulated Macquarie River as it empties into the Macquarie Marshes rather than the Barwon-Darling.

This time series hydrologic modelling was done at the direction of the Connectivity Expert Panel. The panel used the modelling data to inform the proposed protection of base flow and resumption of flow targets presented in Connectivity Expert Panel Final Report 2024. The Connectivity Expert Panel was convened by the Minister for Water to provide advice on the adequacy and potential improvements to rules in the NSW Northern Basin water sharing plans that might materially impact on hydrological connectivity. The Panel was asked to consider the adequacy of current and proposed targets and triggers for restricting supplementary and floodplain harvesting, as well as A, B and C class licences in the Barwon-Darling.

Time series of modelled daily flow rates in megalitres per day across the NSW river systems – Border Rivers Valley. Individual for each available river gauge data sets are attained via best available at the time of publishing hydrologic model/s and over the historic climate period (usually from early to mid-1890s to a water year previous to the date of publishing). Specific scenario data sets are expected to be updated annually and subject to quality requirements may be used in relevant studies. The naming structure of the individual files is "Gauge number_watercourse@Gauge name".
