About Glen Mervyn Dam (Collie)

Glen Mervyn Dam sits 18km south of Collie at Mumballup, off Collie-Preston Road, and it is the small, close, easy one of the South West dams.

Best tide state to fish Glen Mervyn Dam (Collie)

No tide and no swell inland, so the variables are water level, wind across the open water and light. Trout are a cool-water, low-light fish — overcast days and the hours either side of dawn and dusk — and because the fishery is open all year here, winter is genuinely on the table rather than a consolation prize. Summer heat pushes the trout deep and hands the day to the redfin. The shallow, sandy margins along the western shore are the first water to warm; the eastern day-use side is the one with the facilities. Spring, after the annual stocking, is the strongest window of the year.

What anglers target here

Anglers fishing Glen Mervyn Dam (Collie) typically time sessions around the tide for rainbow trout, brown trout, redfin perch, and marron.
