level Greg PETERS
Riverness Pty Ltd, Australia
• Policy framework • Regional strategies and priority waterways • Se?ng targets
Presenta&on outline
Policy framework
Victorian Waterway Management Strategy (2013)
Overarching policy framework for waterways • Presents the vision, principles and management approach
• Sets state policies, acBons and targets
• Facilitated regional decision making
• AdapBve to changed condiBons e.g. droughts, floods, wildfire
Policies and ac&ons -‐ example RecreaBonal use of waterways: • Encourage and support community involvement in waterway planning for, and management of, recreaBonal use of waterways
• Acknowledge the importance of waterways for recreaBon and promote sustainable recreaBonal use
• Manage risks associated with recreaBonal use through guidelines, protocols and educaBon.

Regional Waterway Strategies
Regional Waterway Strategies
• Single, regional planning document for rivers, estuaries and wetlands
• Developed by CMAs in partnership with regional communiBes
• Guide investment over an 8-‐year period – Three Bers of targets – clear program logic – High level regional works program
Asset based approach – AVIRA database
• Assets • river reaches, estuaries and wetlands • Linked to ISC, IWC, IEC
• Consistent set of • Values (+40)

Regional goals
• Developed by each CMA • 20-‐year + Bmeframe • Conceptual or qualitaBve link to management outcomes
• Region wide to drive priority se?ng • 4 – 5 goals (generally)
Using goals to iden&fy priority waterways
• Protect and enhance threatened fish populaBons in the GHCMA region • Score of 4 or 5 for Significant fish, with three or more species idenBfied.
• Presence of Glenelg Spiny Crayfish • Presence of Variegated Pygmy Perch
• Protect and enhance high value recreaBon fishing through habitat protecBon • Criteria : Score of 5 for RecreaBonal fishing

• IdenBfied links between threats and acBviBes • Allowed CMAs to transparently idenBfy acBons to address threats linked to the regional goals
• Included raBng of effecBveness and esBmated response Bme
Works program database
• Built around data outputs from AVIRA • Incorporated the management opBon models • Incorporated standards for reporBng of ‘outputs’ from DELWP
• Included custom reports for works programs • PotenBal use for MER
