Hepburn Lagoon

Imagery © Esri

Hepburn Lagoon is a medium-sized storage a short drive west of Daylesford, and you make the trip for its brown and rainbow trout.

It is one round bowl of water in farmland, and you fish it on foot. Walk the shoreline: it looks featureless from the bank, but weed beds, grassy bays and rocky points sit around it.

Come in winter for baitfish streamers and smelting trout, in spring for mayfly, and in summer for mudeyes. Pick an overcast day if you can. Read the current Victorian Fisheries Authority guide before you go.

Water and habitat

The lagoon is a medium-sized storage surrounded by farmland, with grassy and rocky shorelines. At a glance it looks like a round bowl with little shoreline vegetation, and that first impression undersells it.

Walking it reveals weed beds, grassy bays and rocky points, and more variation than you would guess from the car park end. In our experience those are the places to spend your time: cover and edges, not the open bowl.

Fish and forage

Brown trout and rainbow trout hold here, and both have been stocked over many seasons. The stocking chart shows the pattern, so the practical read is a lagoon with a steady supply of both trout rather than a single stocked year to chase.

The lagoon is extremely fertile. Through a season you can meet mayfly, caddis, damsels, mudeyes and midge, and in winter the trout chase abundant baitfish. That spread of food is why your fly box wants insect imitations for the warm months and a few baitfish patterns for the cold ones.

Other fish are recorded in the lagoon as well, but the fishing here is about the trout.

When to fish it

Winter is for baitfish: streamers and other baitfish imitations produce quality fish, and smelting trout are a listed highlight. Spring is mayfly time, when trout look up and feed on mayfly and other insects. Summer mudeye fishing is a listed highlight.

Overcast conditions generally give the best fishing at Hepburn in any season. On a bright day, fish early or late and expect the trout to be harder work.

How to fish it

In spring, nymphs, small wets or dries fished blind or to risers are productive. If you see rises, cover them; if you do not, fish the edges of the weed beds and the points blind.

A Possum Emerger in sizes 12 to 14 and a Gold Humungous in size 10 are both listed for brown and rainbow trout here, so they earn a place in the box. In winter, put a streamer or another baitfish imitation on and work it along the weed edges and off the rocky points.

In summer, a good bet is to carry a few mudeye imitations.

Access and safety

The lagoon is reached via Pruntys Road at the south-eastern end, or via the Daylesford-Clunes Road. The whole of it is accessible on foot, so you can choose your own start and walk to where the fishing looks best.

Treat that as a description of how people reach the water, not a statement of permission. The lagoon is surrounded by farmland, so read the signs and fences you meet on the ground. As on any lake shore, tell someone where you are going, carry water, and watch your footing on rocky points and wet grass.

Regulations

Before you fish, read the current Victorian Fisheries Authority inland angling guide. Check its closed waters list for the lagoon, and take any season, bag and size limits and licence requirements from it.

A year at a glance; check current rules

  • Baitfish and smelting trout · Jun to Aug FlyLife's writers describe winter trout chasing abundant baitfish, with streamers and other baitfish imitations producing quality fish. Smelting trout are a listed winter highlight. Treat the months as a rough guide.
  • Mayfly rises · Sep to Nov Spring mayfly is a listed highlight. Trout look up and feed on mayfly and other insects, and nymphs, small wets or dries fished blind or to risers are productive.
  • Mudeye fishing · Dec to Feb Summer mudeye fishing is a listed highlight. Take any season and closure for the lagoon from the current Victorian Fisheries Authority guide before you plan the trip.

The share of the mapped water body that was wet each month, from satellite imagery since 1987. This is not a level record — a satellite reads surface extent, never depth — but a shrinking wet area usually means a lower lake. Over 256 months on file the wet share has run from 0% to 99%; the latest reading is 93%, 2026-08.

Capture records by decade — electrofishing, netting, trapping and rotenone surveys only; a sighting, an eDNA water sample or a stocking release is not a capture and is not counted here. A record is not an abundance estimate, and a decade with no bar is a decade with no capture survey on file, not evidence the water was empty.

What the gauges say

Check the water operator or jurisdiction authority for current conditions, and read the water yourself when you arrive.

Questions anglers ask

What will I catch?

Brown and rainbow trout, both managed by fisheries and both stocked over the years. The stocking chart shows which seasons fish went in.

Can I walk the whole shoreline?

The whole lagoon is accessible on foot, and walking it is how you find the weed beds, grassy bays and rocky points that a first look from the bank does not show.

When is the best time to fish it?

Winter suits baitfish patterns, spring brings mayfly, and summer brings mudeyes. Overcast days are generally the best.

Is there a closed season or a bag limit?

Check the current Victorian Fisheries Authority inland angling guide, including its closed waters list, and take any season, bag and size limits and licence requirements from it before you fish.
