A new entitlement was established in April 2018, which will enable water for the environment to be used in the upper Barwon River for the first time in 2018–19. The entitlement provides 1,000 ML per year on average from the West Barwon Reservoir. Given the small amount of available environmental water, deliveries will target the reach between the West Barwon Reservoir and Birregurra Creek confluence, as this is where it can have the most benefit.
