​Weather cycles are all part of outdoor life: hot, cold, wet, dry. Then there are the more complex patterns which may favour a boom of one kind of trout food, or maybe a bust of another. Often these are all but indecipherable to us anglers, no matter how much we might wish otherwise.Through the range of conditions, we are fortunate that Millbrook trout are always there and can be caught… although how that plays out is the question!

2026 at Millbrook started quite hot (by our standards) and dry, although a deluge in February gave valuable respite. Then, since the start of May, the rain has come down consistently: roughly 230mm worth so far for May, June and the beginning of July. The timing of this rain is ideal, falling when evaporation is at a minimum. The result has been significant rises in the levels of all our lakes, and in some cases, they are now full and spilling.

Full lakes don’t guarantee great fishing, just as low lakes don’t mean it’ll be tough. BUT to state the bleeding obvious, the Millbrook Lakes fishery requires water to operate, and after two drier-than-normal years, it’s good to be banking decent quantities of the stuff.

To the actual fishing, and two standouts in recent months have been smelters eating finger-sized galaxias, which have boomed for reasons we don’t really understand (see above!) and good old midge feeders. Floodwater feeders are a thing at times as the lake edges rise over long-exposed shores, flushing terrestrial food like worms and beetles. Once a given lake fills, this exciting if sporadic fishing fades with no more ‘new’ food being flushed, but it’s fun while it lasts! Also, these circumstances (like abundant galaxias) do wonders for trout growth and condition.

When it comes to mayfly, there were some light hatches in autumn, although you couldn’t bank on them. It’ll be interesting to see what happens with the mayfly this spring.
​
As always, we don’t know exactly what the coming months will bring weather-wise, but in the short to medium term, we do know there will be plenty of water, and lots of fat trout.      

​The headline for the last 18 months would be one word ‘Dry’. 2024 was actually the driest year in Millbrook Lakes’ 29 years of operation, and 2025 started off not much better.
 
So, one of the reasons for an absence of reports lately, has simply been a lack of clarity about what to expect going forward? Unlike big rain events, such as regularly occurred in 2022, droughts are much more of a slow burn. Although the actual Millbrook fishing had been performing well through this autumn and into the start of winter, we were aware that just a bit more tough love from Mother Nature, could have tipped things over the edge.  
 
Fortunately, we’ve just had a nice wet June, with over 100mm of rain. After such a prolonged dry spell, even this quantity of rain is not enough to declare the drought over. However, it has reversed the trend of receding water levels. Most lakes are finally rising… at least a little, and in some cases, quite a lot. Meanwhile, our trout stocks weathered the dry remarkably well. In fact, we’ve been surprised at the size and condition of the trout that have ‘reappeared’ in many lakes since the hot dry days of summer. Not for the first time, we’re left amazed at just how resilient our lakes (and their trout) can be. The relatively cool temperatures at 5-600 metres above sea level, carefully managing fishing pressure, and our efforts to maintain water quality – including oxygenated refuges – evidently all helped.   
 
To the current fishing, and the headlines are midging trout, yabby feeders, polaroiding, and the first signs of floodwater feeders. We’re not out of the woods yet, but for the first time in many months, it’s definitely feeling like the glass is half full. 

It’s been a strange few months at Millbrook Lakes. First, it’s been unusually dry – not bone-dry, but enough for us to grateful for the ‘bank’ of storage and groundwater accumulated over the last few wet years. This ‘credit’ has meant that, while some lakes are low for this time of year, many are full or close to it. And temperatures have been topsy-turvy.

August saw maximums significantly above average for the end of winter, and late in the month, we had big dragonfly numbers – a rarity this early in the season. There were even enough for the trout to be leaping for them, and although dragonfly leapers aren’t easy to catch, it was great fun trying, and some beauties were fooled.

Come September, and the temperature switch flicked. It’s been cool to cold, and we even had snowfalls mid-month.

Through it all, the fishing headline has been midge (chironomid). There have been lots – big, small; daytime as well as evening. Trout love midge (they contain three times the protein of steak after all!) and these little bugs have provided endless sight-fishing opportunities. Cockchafer beetles have made a bit of an appearance too, although rarely enough to out-compete the midge action.
​
Regulars will know that we’re also on the cusp of mayfly season. A few early duns have appeared, but so far just short of what we would call a proper hatch. Historically, late September is the earliest we have hatches worthy of the name, and early to mid-October is a more typical start to mayfly season. There are lots of nymphs under the rocks, so it looks promising – although as always, it’s anyone’s guess how big the hatches will be, and how long they will last. Fingers crossed, but meanwhile, the midge are a good backup.                

​After a busy autumn, we’ve now got a chance to take a deep breath, reflect on the last few months, and have a look towards the winter ahead – perhaps surprisingly, one of our favourite times of year to guide.
 
To the last few months first, and guiding got underway in earnest (as usual) from the very start of March. Despite a cool and wet December/ January, by this point, abruptly dry and warm conditions in late summer had left their mark, with a number of lakes having dropped significantly.
 
Low lakes are an interesting proposition for us guides. Over the decades, we’ve come to learn that, providing water quality remains reasonable, lake level has little to do with fishing quality. Aquatic ecology is so complex, some brimming-full lakes can be a bit disappointing, while just down the road, a half empty lake is fishing brilliantly.
 
Many times this autumn, we took guests to one of these half empty lakes, only to find that the sad looks soon evaporated once a 5 pounder was heading to the horizon, towing all their flyline, plus a decent length of backing. Of course, the full lakes (and there are several) can fish well too of course, but there’s no guarantee at all that more water equals better fishing – as a few hundred guests would attest!
 
In terms of detail, while smelters (minnow feeders), mayfly and damsels all played their part, the headline this autumn was probably midge, or more precisely, chironomid. The hatches have been impressive, and not just on evening. And don’t think it’s all about tiny flies either – many of the naturals around here are 10mm right up to 14mm.
 
As we write at the start of winter, the midge action shows no signs of backing off. And with recent rain, some of those low lakes are starting to flood over revegetated ground, with tailers following the rising tide. One definite upside of having a lake drop for a while! Polaroiding shoreline cruisers is big thing too. And on those rough, ‘horrible’ days (well, horrible for humans), pulling a big wet can see the rod just about pulled from your cold hands. As always, time will tell regarding future water levels and conditions, but right here right now is looking good.           

​Since our last update, mother nature has given us a bit of everything. September was warmer and drier than average. That turned out to be something of a false spring however, with October coming in much cooler and wetter. Then November started dry but ended wet. Wind has been a thing too, although the equinox does throw up that atmospheric struggle most years, and so we're used to it (even if we don't necessarily like it).
Wind or not, the fishing has been very good.

​After a few weeks of solid midge and cockchafer beetle action, proper dun hatches started in the last days of September, and have continued ever since. However, we haven't reached the stellar mayfly heights of 2022. While several lakes have been excellent for reliable hatches this spring, some others have been a bit patchy, and a couple of last year's heros have been zeros (or almost).
 
Polaroiding has been very good regardless with lots of clear water, and plenty of actively cruising fish. Another thing which has stood out has been a recent burst of daytime midging fish - not at all typical of this time of year. And the other standout, mayfly or not, has been the extent of the dry fly fishing. We'll cheerfully fish whatever is necessary to get the trout to eat, but it's undeniably a plus when the dry is genuinely as good an option as anything; and sometimes the very best option. 
 
All up, this spring has offered very 'visual' and entertaining fishing - not always easy, but nearly always great fun.

'Water everywhere' would be the two-word summary of Millbrook's winter so far. Despite BOM forecasting a warm, dry autumn and start to winter, so far, it's been anything but. Of course, if BOM keep saying it will be warm and dry, they'll be right... eventually! But meanwhile, one major lake we had to virtually drain in mid-May to replace a leaking valve, subsequently refilled in just six weeks. And Cabin Lake spilled in early July - the earliest it's ever done that. While dry conditions can have their advantages (such as access tracks you can actually drive on) plenty of water is hard to knock back. Trout love it, as do the things they eat - which sort of amounts to the same thing.

Midge hatches have been good, and minnow populations are healthy as breeding conditions are favourable for a third year in a row. Polaroiding the edges when even a bit of light allows, has been very exciting, and on the few lakes which haven't filled yet, rising water is flushing food out of the shallows, thus drawing fish in. It's no surprise that trout size and condition has been excellent, continuing the trend of recent wet months and years.

As guides, we love winter fishing for the many opportunities it provides, and this winter is proving as good as any. BUT remember, you do have to dress for it - especially when the wind gets up, which it has a lot lately.
​
At 600m above sea level, our temps are typically 6C colder than Melbourne, and we're roughly 50% wetter. Layers, gloves, good waterproofs and beanies, will mean you can focus on the fish, instead of how to keep warm.    
​

​      ​Wow, what an eventful 6 months! When we last reported, Millbrook was coming out of a wet and cold winter. Unbeknownst to us at the time, in common with much of Victoria, we were about to enter the wettest spring on record. Being a lake-based fishery, the actual trout action largely went on as normal. If you dressed for the conditions, there were very good dun hatches (not 2021 standard, still impressive) as well as smelters, worm feeders in the flooded margins, damsel leapers – you name it. The biggest downside, practically speaking, was access. A number of tracks to the lakes which we had previously regarded as all-weather, became impassable for hours or even days at a time. Either we walked in, or fished elsewhere.
 
Fast forward to now (early autumn) and a dry-ish summer has completely altered the landscape. Where there was once wheel-deep mud, there’s now dust. Lake levels and water quality have largely held up very well, no doubt thanks to the enormous stores of groundwater which accumulated during 2022. Still, some lakes are well down on their spring highs – great for fishing and killing back choking weed, but aesthetically, not as pretty.
 
Speaking of the fishing, so far this autumn the headline is undoubtedly smelters (trout hammering baitfish). But we’re seeing pleasing numbers of duns too, and the trout certainly remember what duns are! Terrestrials have also made an appearance on warmer days, with beetle patterns in particular doing nicely in such conditions. So it’s full steam ahead for autumn, and so far, so good.              

As a flyfisher, during the dog days of summer, you can find yourself wishing for winter’s chill and abundant water. That wish has been put to the test at Millbrook this winter! It’s been wet and cold, especially in August. 20 rain days delivered 130mm of rain – our second wettest August in Millbrook’s 27 years of existence. On the plus side, every lake is overflowing, and the springs are pumping. On the downside, it’s been a bit of a mud-bath trying to get to or from a few lakes, meaning walking has been the only option. And although the trout are happy with the cold and big living quarters, fishing in rain and icy gales is not something client or guide is likely to miss. Thankfully, the fishing has been really good in spite of the gloomy weather. Midges have tried their best to hatch (they don’t mind cold but dislike rain.) Floodwater feeders have gorged on worms and other flushed goodies, and the smelters have been really good. No cockchafer beetles yet however – maybe the grubs have drowned?  
 
Anyway, as we enter early September, winter is finally losing the battle. Longer daylight hours and a higher sun mean small breaks in the weather have a big impact. The cold and rain won’t be done with just yet, but milder weather is trying its best to push in. After last year’s best every mayfly spring, we are all waiting eagerly (anxiously?) to see what spring 2022 brings. It will have a hard act to follow, but at least the trout are really big, fat and abundant.        

There aren’t too many certainties in flyfishing, but the transition from mild autumn weather, to wintry, happens with surprising predictability at Millbrook sometime in the first or second week of May. It is when, for example, that gloves and beanies go from being occasionally handy, to something you always want to have in the car at the very least.
 
With the change in seasons, the fishing changes too. Mayfly, mudeyes and terrestrials are all but gone, fortunately replaced by midge, and to a lesser extent, caddis. If the attrition rate of flies is any indication, buzzers and stick caddis are now the patterns  of choice more often than not; supplemented by big wets.
 
It would be reasonable to think that this shift towards cold weather would mark a decline in the fishing which won’t reverse until spring. But in fact, May is more of a reset month at Millbrook. Fish are still caught, and some big ones. Yet ironically, June, July and August often provide more consistent fishing, as the trout settle into their new chilly world. (They are, after all, a cold water species.)
 
The main thing for anglers to do, is stay warm. We often suggest our guests treat a Millbrook winter trip like a trip to the snow, and dress accordingly – minus the bright colours of course! Do that, and winter can provide some of the most enjoyable action of the year.
