33.GoulburnIn central Victoria, the Goulburn River and its associated floodplain and wetland habitats support intact river red gum forest; and numerous threatened fish, mammal and bird species. The Lower Goulburn floodplain covers some 13,000 ha alongside the river channel from Goulburn Weir to the River Murray junction and contains many important cultural heritage sites. Potential constraints to environmental flow delivery in the Goulburn valley consist mainly of third party inundation impacts below Lake Eildon and around Shepparton; and timing issues to be able to supplement unregulated tributary inflows with storage releases. To achieve higher managed flows downstream of Goulburn Weir, unregulated tributary flows downstream of Lake Eildon would need to be supplemented with either Lake Eildon releases and/or adjustments to Waranga Basin harvesting operations. Importantly, large releases relying solely on Lake Eildon are unlikely to be feasible. The reach between Lake Eildon and Goulburn Weir has a much lower channel capacity, and landholders and businesses near Alexandra and Molesworth start to get affected when any flows get above 10,000 ML/day. The role of unregulated tributaries is critical for the future of higher managed flows in the lower Goulburn system.
Consultation with landholders and communities in the Goulburn valley has commenced. Three regional advisory groups have been formed to assist MDBA with capturing the key issues and impacts likely to arise from increased flows. MDBA’s regional consultation and analysis of the available technical work indicates that more frequent overbank environmental flows downstream of Goulburn Weir are feasible. In addition to information gathered through the regional advisory groups, consultation during the public comment period captured a broad range of overbank flow issues likely to be experienced along the Goulburn River. Several people commented that the MDBA consultation process in the Goulburn region has been good and is beginning to capture local knowledge well. The priority actions listed for the Goulburn River were strongly supported. It was also recognised by a number of people that environmental flows will add to the biodiversity and value of the natural environment and may have positive economic outcomes, while having the additional potential to add to the amenity and quality of life for residents and visitors. People also provided specific feedback on impacts or other issues that will be considered in future work on implementing the Strategy, including:
