Harvey Dam

Harvey Dam is the South West's flagship stillwater trout fishery — a 2002-built impoundment that took over from Waroona Dam as the premier trout water south of Perth, an easy 1 hour 40 from the city off South Western Highway. DPIRD stocks it heavily every year with brown and rainbow trout — recent seasons have put around 5,400 mature fish into the dam plus another 20,000 fry into the Harvey River and Falls Creek above it — and that stocking is what drives the quality. Redfin perch are prolific, the marron are genuine trophy class under their own summer season, and the recreation area wraps it all in barbecues, lawns and a playground. It's the rare serious fishery you can bring the whole family to without apology.

Trout are caught right through the dam, from the wall to the tail, so cover water until you find them. Weaving a lure or fly between the submerged trees at the eastern end is the classic way to find cruising fish — expensive in snags, productive in trout. The Falls Creek arm is the shore-walker's water, with good numbers of browns and rainbows for those prepared to work the banks, and the shallow margins fish best late in the day as trout move in to feed. A kayak or canoe opens the tree lines and deeper edges properly — power boats are prohibited, which keeps the water calm and the fishing honest. Redfin want small lures and soft plastics worked around structure; marron are snare-only here, in season, after dark.

Brown and rainbow trout are the primary target, running from freshly stocked fish to solid holdovers. Redfin perch are everywhere — often small, occasionally excellent, and as a declared pest they must not be returned to the water; the upside is they're first-rate eating. Marron in the summer season are the big-claw bonus: Harvey Dam is designated trophy waters, so the marron run larger here and the rules run tighter — 90mm minimum carapace, a bag of five, snares only. That combination of table trout, feed-of-redfin reliability and trophy marron is why the car park fills on spring weekends.

Sort the paperwork before you leave Perth — a South West Freshwater Angling Licence covers the trout and redfin, and marron need their own separate licence on top, with the season only running a few summer weeks. Dawn and dusk are the working windows, and a warmish October or November afternoon often brings a proper late-afternoon rise. The banks can go soft after rain, so watch where the family car parks. Take a snag-retriever or spare lures for the eastern tree lines, and keep any redfin you catch — the dam and DPIRD both thank you.

Turn onto Weir Road about 2.5km off South Western Highway at Harvey — roughly 140km and 1 hour 40 from Perth. The recreation area is day-use and well equipped: toilets, barbecues, picnic gazebos, grassed areas, a fenced playground, walking trails and a lookout over the 45m dam wall via the spillway path. There's a boat ramp for paddle craft and several easy kayak launch spots along the southern side, with plenty of bank access where a standard car can safely park. Camping is not permitted at the dam itself. Mobile coverage is limited to nonexistent — download maps and tell someone your plans.

This is a working irrigation dam, so the level moves through the year and the bank you fished in spring can be a mudflat by late summer. Cool, overcast days and low light are trout weather; bright summer heat pushes fish deep and hands the fishing to the redfin. The late-afternoon rise on warm spring days is the event locals plan around. After winter rain the tributary arms colour up first while the main basin stays workable, and soft banks are part of the deal.

The banks can be soft and boggy after rain — more of a risk to the car than the angler, but both have been lost to worse. The submerged trees that hold the trout also hold kayaks; keep a straight line out of the timber and wear the life jacket. Mobile reception at the dam is unreliable, so don't count on a phone in an emergency, and check Emergency WA for bushfire warnings in the hotter months before driving down. Power boats are prohibited — paddle craft only — which removes the wake but not the cold water; winter capsizes are a real hypothermia risk.

Yes — a South West Freshwater Angling Licence from DPIRD is required to fish for trout and redfin in freshwater south of 29°S, and marron need a separate Recreational Marron Licence on top. Fishing from the bank or a kayak without the freshwater licence is an offence even if you release everything.

Harvey Dam is designated trophy waters, so the rules are tighter than standard: 90mm minimum carapace length, a daily bag of five per licensed fisher, and snares are the only legal capture method — no drop nets or scoops. The season is short, running from noon on 8 January to noon on 5 February, and a separate marron licence is required. Check DPIRD's current marron guide before the season.

Paddle craft only — kayaks and canoes launch from the ramp and several spots along the southern side, but power boats are prohibited on the dam. That suits the fishing: a kayak is the best way to work the submerged tree lines at the eastern end where the cruising trout hold.

No — the recreation area is day-use only, though it's well set up with toilets, barbecues, picnic shelters, a playground and walking trails. The nearest camping options are in and around Harvey and the wider South West dam circuit, including Potters Gorge at Wellington Dam near Collie.

Small minnow-style hard bodies, soft plastics and small vibes on a light 1.8–2.1m spin outfit with 3kg line cover the lure side; fly fishers do the damage with Woolly Buggers and Mrs Simpson streamers around the margins. Dawn, dusk and the warm-afternoon rises of October and November are the windows to plan around, and the eastern timber is where to look for cruising fish.

Redfin perch are a declared pest in WA and must not be returned to the water alive — DPIRD asks that they're humanely dispatched and not left on the bank. There's no bag limit on them. The consolation is that redfin are excellent eating, so a bag of Harvey Dam reddies is a feed, not a chore.
