This report determines the most appropriate watering actions for Barwon Water to make best use of the additional water now available in the Painkalac Reservoir. These watering actions specifically detail potential flow releases from the reservoir that benefit key ecological parameters of the creek and consider the specifics of the system as well as its limitations. 

Barwon Water,

Corangamite Catchment Management Authority

Barwon Water have recently upgraded the water supply for Fairhaven and Aireys Inlet and as a result, the Painkalac Reservoir is no longer being used to supply water to these townships. This then provides other opportunities for the potable water allocation stored in Painkalac Reservoir to be used for alternate purposes, such as for recreation or environmental benefit. This proposal is focused on the latter and is intended to provide a summary of a Flows Study conducted in 2008 (Doeg et al. 2008) as well as provide guidance on the potential use of the water from the reservoir for environmental benefit to the creek. 

The scope of this report was to determine the most appropriate watering actions for Barwon Water to implement, that make best use of the additional water now available in the reservoir. These watering actions specifically detail potential flow releases from the reservoir that benefit key ecological parameters of the creek and consider the specifics of the system as well as its limitations.
