Water

We rely on water to generate electricity, but we also manage this shared resource to balance the need for irrigation, town water supply, aquaculture, recreation, aesthetics, and biodiversity.


Water releases


We try to accommodate all uses of the water that we manage, where we can, and where it does not adversely impact hydro-generation activities.

We receive between 150 and 200 water level and flow requests every year and we can normally accommodate around 80% of them.

We currently arrange for specific lake levels for rowers, paddlers and anglers; and for construction projects.

Specific flows on rivers are requested by paddlers / kayakers / rafters for leisure, training and competitions. No flow or low flow is requested for in river works and construction projects.
