Blagdon Lake
Reservoir · Fresh water · in The English trout reservoirs
The oldest reservoir trout fishery in England, a narrow lake in a wooded Mendip valley with a marl bed, dense insect life and a strong fly-fishing tradition.

What you can catch here
Documented at this place, grouped by how you would be fishing, with how strongly the sources support each one. This is what has been written down, not a forecast, and being listed is never permission to fish.

What these strengths mean
- Characteristic of this water
- This water is strongly identified with this species by the sources that cover it.
- Regular local target
- Fishing sources describe this as a normal local target here, not merely as caught.
- Recorded here
- At least one credible public account of this species being caught here. That is all it means.
- How breadth is counted
- A fish documented at six marks is shown as six marks: breadth never raises the strength on its own. A fishery account describes the fishing; a recorded catch reports one specific catch. How evidence is weighed.
How people fish it
Practised here: Fly fishing.
Methods the sources name for this ground. Each one is explained in full on its own page.
- Stillwater fly fishing
Fly fishing without current, where the angler supplies every movement and the problem becomes finding fish rather than presenting to them.
Baits and lures for these fish
The baits and lures each of the fish above is commonly taken on, from that fish’s own page. This is what works for the fish, not a report of what people use on this particular water — local knowledge and the conditions on the day still decide.
Baits
- Lobworms and worms — for European perch
- Sea deadbaits — for Northern pike
Lures
- Crankbaits — for European perch, Northern pike
- Dry flies — for Rainbow trout, Brown trout
- Nymphs — for Rainbow trout, Brown trout
- Soft plastics — for European perch, Northern pike
- Spinners — for Rainbow trout, European perch
- Streamers — for Rainbow trout, Brown trout
- Jerkbaits — for Northern pike
- Jigs and jig heads — for European perch

Safety
Cold water shock — Can cause serious injury or death
A warm surface layer sits on cold deep water through the summer. Immersion in August is immersion in cold water, the involuntary gasp and loss of breathing control arrive in the first seconds, and off a steep margin or from a boat there is nothing shallow to stand up in.
What reduces it: Wear a buoyancy aid rather than carry one, do not fish alone from a boat, and treat these lakes as cold water in every month because below the surface they are.
Worse when:
- In summer, when the warm surface makes the lake feel safe.
- Off dam walls, rip-rap and steep drawdown margins, where there is no shallow water to recover into.
Boat safety — Can cause serious injury or death
A large open reservoir gives wind a long uninterrupted fetch, so a steep sea builds quickly and a boat that could make ground half an hour ago may not now. The shore under the lee may be bare drawdown bank or rip-rap with nowhere sensible to land.
What reduces it: Follow the fishery's boat and buoyancy aid rules, which are the operative framework. Fix a turnaround time and a named landing shore before setting off, and go in early when the wind starts rather than after it has built.
Overhead power lines — Can cause serious injury or death
Overhead electricity lines cross some reservoir approaches and margins. Carbon rods conduct and electricity arcs across a gap without contact, so raising a rod beneath a line kills instantly.
What reduces it: Look up before setting up and before moving with a rod raised, and do not fish a swim with a line over or near it.
Rules and access
Licence
A rod licence is required for freshwater rod fishing in England, issued by the Environment Agency.
Permission to fish
Separate. Almost all fishing rights are held by a club, association, riparian owner or navigation authority, and the licence does not grant access to any of them.
FishingHQ does not know the current access position here. Freshwater rod fishing in England requires a current rod licence AND separate permission from whoever controls the fishing, which is frequently a club, riparian owner or navigation authority rather than a public body. Close seasons, byelaws and local rules apply and change. Check with the Environment Agency and with the controlling club or owner before going.
Who holds the answer:
- The Environment Agency, for rod licensing, close seasons and fisheries byelaws in England.
- The club, association, riparian owner or navigation authority that controls the fishing.
- The Environment Agency, for rod licensing in England and for fisheries enforcement.
- The water company or fishery operator that runs the reservoir, whose own rules govern methods, bag limits, boats and access and are the operative constraint.
- Natural England and the site management body, where a reservoir carries a conservation designation affecting access, disturbance or timing.
- The fishery lodge or manager on the day, for boat safety requirements, buoyancy aid rules and any conditions in force.
The fishery on this water
This water is public geography and is also somebody’s business. What follows is the operator’s own account of the fishery that runs on it: what they stock, how you get a day, and the conditions they set.
These are the operator’s rules, not the law. A fishery can require barbless hooks, refuse a method, close a water or ask you to leave, and none of that is a legal requirement. The licence and the close season are set by the fisheries authority and are the section above. Being listed here is not a recommendation and it is not permission — telephone before travelling.

- Flies no larger than two inches, and no fly heavier than five grams.
- Leader strength must not exceed twenty-five pounds, and wire traces and armoured tippet are not permitted.
- Pike fly fishing is not permitted, and the operator states that carrying pike fly tackle here will result in an immediate ban.
