Lake Toolondo is an off-stream reservoir famous for its great trout fishing and is a popular recreational destination in the region.

Supplied by its own small catchment from Mt Talbot Creek, the lake stores a lot of 'dead water'. This means that water in Lake Toolondo doesn't flow through to another source; it can only be pumped out. The lake is reliant on transfers from Rocklands Reservoir.


Be sure to play it safe around water.

Read our information signage before entering the water.
