The Old Bedford River and the Delph
Drain · Fresh water · in The Fens and their drains
Two straight seventeenth-century artificial channels running parallel across the Fens with the Ouse Washes flood storage area between them: uniform width, steep clay banks, silt bed, and no natural features at all.
Safety: drowning and immersion — can cause serious injury or death. 2 more points apply here.
FishingHQ describes what this place is. It does not say whether you may fish it: access rights, permits, licences, byelaws, closures and protected areas all apply, all differ and all change. Who to ask is below.
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
- Established quarry
- Fishing sources describe this as a normal local target here, not merely as caught.
- Repeatedly reported
- Several independent public accounts. Enough to say it happens more than once; not enough to call it a fishery.
- Places, accounts and sources are counted separately
- A fish documented once at each of six marks is still documented once at each of six marks. Breadth is reported as a place count and never raises the strength, and sources are deduplicated across places so one publisher covering a whole coast counts as one. A fishery account is a source describing the fishing; a recorded catch is a report of a specific catch. They are counted apart because they are not the same evidence.

How people fish it
Practised here: Coarse fishing.
Methods the sources name for this ground. Each one is explained in full on its own page.
- Float fishing
Suspending a bait at a controlled depth beneath a buoyant indicator — the most visual, most controllable and most widely applicable method in angling.
- Ledgering
Fishing a bait on the bottom held by a weight, with no float — the simplest way to fish at distance, in depth, or in wind.
- Deadbaiting
Presenting a dead fish as bait for predators — a method that works because scavenging is normal predator behaviour, not an exception.
- Spinning
Casting an artificial lure and retrieving it so that it moves like something alive — the most direct form of lure fishing.
The ground and the water
- The ground
- Two straight seventeenth-century artificial channels running parallel across the Fens with the Ouse Washes flood storage area between them: uniform width, steep clay banks, silt bed, and no natural features at all.
- Exposure
- Total. The Fens are the flattest land in Britain and there is nothing at all to break the wind on a drain bank.
- Depth
- Shallow and uniform, which is characteristic of every Fenland drain and is why they fish so differently from rivers.
- Tide and flow
- Not tidal, but heavily managed — levels are set by pumping and by flood operation, and the washes between the channels flood deliberately in winter, which is the defining event of the fishery's year.
Through the year
A winter predator fishery of long standing — pike and zander in cold, clear water — with roach and bream through the warmer months. The annual flooding of the washes redistributes fish through the whole system and is the reason the fishery is unpredictable year to year.
Safety
Drowning and immersion — Can cause serious injury or death
Fen drain banks are steep, high, smooth clay above cold water with no shallow margin and no natural handhold. Somebody who goes in cannot climb out at the point they entered, and the bank is frequently unfenced and unlit.
What reduces it: Test the bank before committing weight, wade only where you can see or have felt the bottom, wear a buoyancy aid on any water you would not want to swim in clothes, and do not fish alone at night on a steep or undercut bank.
Cold water shock — Can cause serious injury or death
UK coastal and inland water is cold enough for most of the year to trigger the involuntary gasp and the loss of swimming ability that decides most immersion deaths, and it does so within the first minute, long before hypothermia is relevant.
What reduces it: Wear a buoyancy aid rather than carry one, carry a means of calling for help on the person rather than in a bag, and plan on the assumption that an unplanned entry into the water is survivable only if somebody knows immediately.
Fishing alone — Can cause injury needing treatment
The Fens are remote, featureless and largely without mobile coverage in places, and a drain bank in winter can be several kilometres from the nearest occupied building.
What reduces it: Tell somebody the specific drain and access point, not the general area; carry a means of calling for help on the person; and do not fish a remote bank alone in winter darkness.
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.
Particular to this water: This ground carries conservation designations that constrain access, vehicles, bait collection and disturbance independently of any fishing rule.
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 national fisheries authority for England, for rod licensing, byelaws, close seasons and fisheries enforcement.
- The internal drainage boards, which operate the pumping stations and sluices and manage water levels across the system.
- The navigation authority for the navigable rivers and channels within the system.
- The angling club, consortium or landowner controlling the specific water, for permission to fish it.
- The authorities responsible for invasive and non-native species, for the rules on moving or returning particular fish.
- The internal drainage board and the Environment Agency, as the bodies that manage water levels and the flood operation.
