What fish are in Big Brook Dam?

Big Brook Dam holds DPIRD-stocked rainbow and brown trout, naturalised redfin perch, and marron in the short summer open season. The trout are the headline draw — the dam receives one of WA's larger annual trout releases, ranging from fry and yearlings up to trophy broodstock fish over 50cm. Redfin are a declared pest and must not be returned alive to the water.

Do you need a licence to fish Big Brook Dam?

Yes — a South-West Freshwater Angling Licence from DPIRD is required to fish for trout or redfin perch in WA's inland south-west waters, and it is separate from the marine recreational fishing licence. Chasing marron in the short summer open season — early January into early February — needs an additional, separate Recreational Marron Licence on top of that. Read the current DPIRD freshwater guide for season dates, bag and size limits before you fish.

Is there trout in Big Brook Dam?

Yes — Big Brook Dam is one of WA's premier trout fisheries and is stocked annually by DPIRD with both rainbow and brown trout, including trophy-sized broodstock fish. Trout fish best at first and last light through the cooler months, and the months just after the winter stocking release are the prime window. Stocking quantities and timing vary year to year, so check current Recfishwest and DPIRD updates before booking a trip.

Can you swim and kayak at Big Brook Dam?

Yes. Unlike most south-west drinking-water catchments, Big Brook Dam is managed for recreation — swimming off the sandy beach, canoeing and kayaking are all allowed, and a sealed 4km loop track follows the shore. That makes it an easy family trip: fish a point at first light and let everyone swim once the day warms up.
