  Your Say: Boundary Creek and Big Swamp remediation

Background

Recent technical work has confirmed that the operation of the Barwon Downs borefield over the past 30 years is responsible for two-thirds of the reduction of base flow into Boundary Creek, with dry climate accounting for the remaining third.

This suggests that the lower sections of Boundary Creek would likely have no-flow periods during summer regardless of groundwater pumping, however pumping has increased the frequency and duration of no-flow periods in lower reaches of Boundary Creek.

 

Community and stakeholder working group

Barwon Water has formed a community and stakeholder working group to develop a remediation plan for Boundary Creek and Big Swamp.

The group includes community and stakeholder representatives from the Corangamite Catchment Management Authority, Colac Otway Shire Council, Land and Water Resources Otway Catchment, People for a Living Moorabool, Upper Barwon Landcare Group, Boundary Creek landowners, Traditional Owners and community members.

The group will work together to assist Barwon Water in designing and implementing a remediation plan for the creek and Big Swamp, with the goal of returning the creek to a healthy ecosystem.
