Llandegfedd Reservoir
Reservoir · Fresh water · in The Severn Estuary
A fertile lowland reservoir in a shallow Monmouthshire valley, with weedy bays, a soft bed and a long-established stocked trout fishery.
Safety: moving water and currents — can cause serious injury or death. One more point applies here.
FishingHQ describes what this place is, not whether you may fish it. Access, permits and who to ask.
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.
- Seasonal
- Well supported, and concentrated in part of the year rather than spread through it.
- Repeatedly reported
- Several independent public accounts. Enough to say it happens more than once; not enough to call it a fishery.
- 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.
The ground and the water
- The ground
- A fertile lowland reservoir in a shallow Monmouthshire valley, with weedy bays, a soft bed and a long-established stocked trout fishery.
Safety
Moving water and currents — Can cause serious injury or death
Tidal streams here are among the strongest around Britain and are unsurvivable to swim against. Underwater visibility is effectively nil, so anybody in the water cannot see and cannot easily be seen. Soft mud can trap a person, and being stuck in mud on a rising tide in this estuary is a recognised recurring emergency.
What reduces it: Stay off soft mud entirely, fish from hard ground, wear a buoyancy aid where there is any chance of going in, and if trapped in mud call for help immediately rather than after struggling. Do not enter the water for any reason.
Cold water shock — Can cause serious injury or death
Water temperature is low enough for most of the year that immersion triggers gasping and hyperventilation, and the ability to swim is lost in the first minute. Combined with a strong tidal stream and zero visibility, an immersion here is a very serious event at any time of year.
What reduces it: Wear a buoyancy aid, keep off slippery hard structures near deep fast water, and if immersed, float and control breathing before attempting anything else.
Rules and access
Licence
A rod licence is required for freshwater rod fishing in Wales, issued by Natural Resources Wales.
Permission to fish
Separate. Fishing rights are held by clubs, associations, riparian owners or navigation authorities, and the licence does not grant access to any water.
FishingHQ does not know the current access position here. Freshwater rod fishing in Wales 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 Natural Resources Wales and with the controlling club or owner before going.
Who holds the answer:
- Natural Resources Wales, for rod licensing, close seasons and fisheries regulation in Wales.
- The club, association or riparian owner that controls the fishing.
- The environment agency in England and natural resources Wales, for migratory salmonids, eels, elvers and the historic net and fixed-engine fisheries.
- The inshore fisheries and conservation authority for the English side, and the Welsh government's marine and fisheries function on the Welsh side, for sea fishing.
- The statutory nature conservation bodies, for the European habitat and bird designations and the site of special scientific interest covering the estuary.
- The harbour authority for the port and navigation areas, whose rules govern access to piers, walls and navigable channels.
- The local authority and food standards agency, for shellfish ground classification and biotoxin monitoring.
