Autumn Trout Fishing: Fry Feeders and Back-End Reservoir Tactics
By Alex Clayton · Updated 2 November 2026
Plenty of anglers pack the fly rod away in October, just as the reservoirs start to fish for fry feeding trout. From October to the end of the season, trout feed hard on coarse fish fry before winter, the big fisheries keep stocking, and rainbow trout in stillwaters have no close season in England or Wales.
The catch is that back-end fish behave differently. Summer buzzers and dries on their own won’t do it.
This page covers which waters stay open, what the law allows, and how to find and fish fry feeders through autumn reservoir fishing. It is part of our autumn fishing guide and covers England and Wales only, because Scottish and Northern Irish rules differ.
Why the Back End Is Worth Fishing
Falling temperatures and shorter days sound like poor trout weather, yet the back end can produce some of the season’s best fish. Three things line up at once.
First, fry. Roach, perch and other coarse fish hatched in summer gather in the margins from late summer into autumn, and trout move in to feed on them before winter. Fish that spent July cruising open water on buzzers now have a reason to come close to the bank.
Second, stocking. Anglian Water’s 2024 stocking policy says it increases stocking frequency again in September and October to support autumn and winter fishing. Check the current policy on the Anglian Water Parks site before planning a trip around it.
Third, big browns. The same policy describes grown-on brown trout of 4lb to 10lb+ (about 1.8kg to 4.5kg+) as a feature at Rutland and Pitsford in October and November. Brown trout are no-kill at those waters, so handling matters (see the session plan below).
It isn’t easy fishing every day. Many anglers find sport patchy while the water turns over, though the banks are usually quieter and back-end fish are generally in good condition.
In summer, trout spread over the whole water on buzzers. In back end trout fishing, they follow food into more predictable places.
Which Reservoirs Stay Open Into Winter
Anglian Water’s big three, Rutland, Grafham and Pitsford, all run their 2026 trout seasons to 31 January 2027, so all three are open through November and December.
| Reservoir | Operator | 2026-27 trout season |
|---|---|---|
| Rutland Water | Anglian Water | 14 March 2026 to 31 January 2027 |
| Grafham Water | Anglian Water | 7 March 2026 to 31 January 2027 |
| Pitsford Water | Anglian Water | 28 February 2026 to 31 January 2027 |

After 31 January, Anglian Water’s 2024 stocking policy says its fisheries close for 4 to 6 weeks while the boats are serviced and pre-season stocking begins.
Season-end dates for Chew Valley Lake and Blagdon, run by Bristol Water Fisheries, could not be confirmed from the operator at the time of writing. The same goes for Draycote Water, which reopened in May 2025 under Anglian Venture Holdings. Check bristolwaterfisheries.com and anglianwaterparks.co.uk for current dates rather than relying on old listings.
Smaller day-ticket rainbow stillwaters often fish all year, but each sets its own rules, and opening hours shorten as the light goes. Check with the fishery before you travel.
Close Seasons: Rainbows, Browns, Rivers and Stillwaters
The idea that “the trout season ends in October” comes from rivers, and it trips people up on stillwaters. The law treats rainbows, browns, rivers and stillwaters differently, and England and Wales don’t match.
| Water | England (Anglian region byelaws) | Wales (NRW) |
|---|---|---|
| Rainbow trout, stillwaters | No close season | No close season |
| Brown trout, enclosed (England) or fully enclosed (Wales) stillwaters | No close season | No close season |
| Brown trout, unenclosed (England) or other (Wales) stillwaters | Close season 30 October to 31 March | Open 20 March to 17 October |
| Trout in rivers | Close season 30 October to 31 March (brown and rainbow) | Rainbow open 3 March to 30 September |

The England column is the Anglian region. Other Environment Agency regions set their own byelaws, so check the GOV.UK regional byelaws page for your area.
Fishery rules sit on top of the law: a reservoir can close earlier or set its own catch and release rules. You still need a rod licence in England and Wales whatever the season.
Our fishing seasons guide has the full picture across species, and the salmon and sea trout runs page covers migratory fish on rivers.
If you fish an unenclosed water for browns after late October, check the byelaw before you go.
What Fry Feeding Looks Like and How to Spot It
Fry feeding trout, browns especially, charge into shoals of small coarse fish, stun or injure some, then turn back to pick off the casualties. Find that activity and you’ve found the fish.
It usually happens where fry shelter: margins, weed beds, boat jetties, dam walls and valve towers. Anglers watch for a handful of signs:
- Fry scattering or spraying out of the water
- Heavy boils and swirls rather than neat sipping rises
- Gulls or grebes working a tight patch of water
- Dead or dying fry floating in the surface film
Timing varies from water to water. Fry feeding is commonly seen from late summer through autumn and tails off as the water cools, but there is no fixed date to set a calendar by.
Before you set up, walk the bank and watch for 10 to 15 minutes. The birds will often point you to the right spot before the trout show themselves.
Fry feeders are a bank angler’s chance, because the action is so often close in. If you see none, don’t force it: the depth-searching approach in the reservoir section below is the fallback.
Fry Patterns and How to Fish Them
Match the fry’s size and behaviour, then slow down. A static or near-static fry often beats a fast strip at the back end.
Fly fishing writer Charles Jardine, writing for the Countryside Alliance, recommends fry patterns for trout on autumn stillwaters: Mink Zonkers, rabbit-based patterns, and foam or deer-hair floating fry, fished slowly or left static.
By autumn the fry are commonly a couple of inches long, so a small summer lure can look wrong. Many anglers size up their fry patterns at this time of year.
| Situation | Pattern type | Line | How to fish it |
|---|---|---|---|
| Fish smashing fry at the surface | Floating fry (foam or deer hair) | Floating | Cast near the disturbance and leave it still, with the odd twitch |
| Fish feeding just under the surface | Zonker or rabbit fry | Floating or slow intermediate | Slow figure-of-eight |
| Fish deeper along a drop-off | Weighted fry | Intermediate or sinking | Count down, then retrieve slowly |
The first row is the “dead fry” approach: the fly imitates a stunned fish lying in the film, waiting for a trout to come back for it. If fish are visibly on fry, try it first.
Fish are bigger and takes are hard, so a common choice is around 8lb to 10lb fluorocarbon rather than a light summer tippet. Check the fishery’s rules on barbless hooks and lure restrictions before you tie on.
Matching fry is matching the hatch with a fish instead of an insect. For line and leader basics, see our stillwater fly fishing guide.
Reading a Back-End Reservoir: Depth, Wind and Banks
A reservoir in autumn can look dead, with fish holding at a different depth from one day to the next.
As surface water cools, the layers that formed in summer mix. Many anglers find fish are scattered during this turnover and change depth often, which is why yesterday’s hot spot can be empty today.
Search depth methodically. Use an intermediate or sinking line and count down, changing the count every few casts until you get a pull. Note the count that worked and repeat it.
Let the wind pick your bank. Fishing the bank the wind blows onto is a long-standing reservoir habit, because food and fry can be pushed there, and wind lanes are worth a cast whenever they form. Beyond that, look for features:
- Dam walls and valve towers
- Points and drop-offs
- Weed edges
Water levels can be down after summer, exposing margins and moving the drop-off further out. Adjust your casting distance to reach it.
If nothing happens in an hour, change speed before you change fly. Retrieve pace is often the difference on a slow autumn day.
What you see on arrival decides the approach. Visible fry activity means fish the fry. A flat, quiet water means pick the windward bank or a feature and start counting down.
A Simple Back-End Session Plan and Looking After Big Browns
Put together, a back-end day comes down to a simple order of play:
- Before you go, check the fishery website or phone for opening hours, recent stocking and where fish are showing.
- On arrival, walk and watch for fry activity.
- If fish are on fry, fish a floating fry static.
- If not, pick the windward bank or a feature and search depth.
- Change retrieve pace before changing fly, and move if nothing happens after an hour or so.
- Plan around the short day: last light comes early in November and December.
Most autumn reservoir fish will be stocked rainbow trout, but the big browns need more care. Anglian Water’s 2024 stocking policy makes browns no-kill at its reservoirs, so check the current rules. Use barbless or debarbed hooks where required, a large soft landing net and wet hands. Keep the fish in the water where you can, support it until it swims off, and keep the photo quick.
Frequently asked questions
Can you still fish for trout in November?
Yes, on most stillwaters. Rainbows have no stillwater close season in England or Wales, and Rutland, Grafham and Pitsford stay open until 31 January 2027. In the Anglian region, rivers and unenclosed brown trout waters close from 30 October. See our fishing seasons guide for other areas.
What is the back end in trout fishing?
The back end is the final stretch of the trout season, roughly October onwards on reservoirs. Trout feed on coarse fish fry, fisheries step up stocking, and big grown-on browns show at waters such as Rutland and Pitsford.
What is the best fly for fry-feeding trout?
A fry imitation sized to the local fry. Charles Jardine suggests a floating foam or deer-hair fry fished static when fish are hitting the surface, and a Mink Zonker or rabbit fry on a slow retrieve when they feed below it.
When do Rutland, Grafham and Pitsford close?
All three close on 31 January 2027. Anglian Water's 2024 stocking policy says its fisheries then stay shut for around 4 to 6 weeks for boat servicing and stocking. Check with the fishery before you travel.
