Monknash and the Nash ledges

Rock mark · Salt water · in The Severn Estuary

Limestone ledges running out below the Heritage Coast cliffs west of Nash Point, uncovering on the ebb into a mixture of rock, gravel and sand. The ledges are what is fished; they are flat, they are wide, and they are under water for most of the tide.

Safety: cliffs and rock platforms — can cause serious injury or death. 3 more points apply here.

What each one does, and what reduces it ↓

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

Regular local target: Fishing sources describe this as a normal local target here, not merely as caught.
Seasonal: Well supported, and concentrated in part of the year rather than spread through it.
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.

Fish documented nearby, not here

Nothing below has been documented at Monknash and the Nash ledges itself. Each one has been documented at a named place on the same ground, and the places are listed with it. Treat this as what the water around here holds rather than as a catch list for this mark.

Widely documented on this ground

Documented at three or more neighbouring places, fished a way this place is also fished. That is a pattern about the ground rather than about any one mark, and it is the closest this site comes to saying you will probably meet a fish somewhere nothing has been written about.

One or two accounts each, on the ground around here. Enough to know the fish is caught in these waters; not enough to say anything about this place.

How people fish it

Practised here: Sea fishing.

Methods the sources name for this ground. Each one is explained in full on its own page.

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.
Surfcasting
Casting heavy baited tackle from a beach into surf — a method defined by distance, by tide, and by reading water that all looks the same.

The ground and the water

The ground: Limestone ledges running out below the Heritage Coast cliffs west of Nash Point, uncovering on the ebb into a mixture of rock, gravel and sand. The ledges are what is fished; they are flat, they are wide, and they are under water for most of the tide.
Exposure: Open south-west, and the ledges are exposed by the swell that makes them fishable.
Tide and flow: Fished around low water when the ledges are out. The Bristol Channel range means that window is short and the return is uphill.

Not to be confused with Nash Point, which is a separate record for different ground.

Through the year

The months the sources attach to each species here. Where a species carries no season it is listed underneath rather than assumed to run through the year.

Safety

Cliffs and rock platforms — Can cause serious injury or death

Anglers are swept from rock platforms by individual large sets rather than by the average sea, which means the conditions that kill people frequently look survivable for the twenty minutes before they arrive. Wet rock, weed and a swell running onto a sloping platform remove any chance of recovery.

What reduces it: Watch the water for a full set cycle before committing to a position, know the escape route and how long it takes, wear a flotation aid rather than carry one, never fish a platform alone, and treat a rising swell forecast as a reason not to go rather than a reason to be careful.

Tides and being cut off — Can cause serious injury or death

The flood fills the ground behind an angler before it covers the ground in front, so the water arrives between them and the shore while the position they are standing on is still dry.

What reduces it: Read the tide table before going rather than after arriving, set a leaving time from the tide rather than from the fishing, and identify the exit and how long it takes while the ground is still uncovered.

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

FishingHQ does not know the current access position here. Shore angling in Wales is not rod-licensed, but access rights, landowner permission, local authority and harbour byelaws, national and inshore fisheries measures, and site designations all apply and all change. Check the current position with Natural Resources Wales, the harbour or local authority, and the landowner before going.

Who holds the answer:

Natural Resources Wales, which administers marine and fisheries regulation in Welsh waters.
The local authority and, where one exists, the harbour authority, for access, byelaws and shellfish classification.
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.

On a narrow screen the plot is wider than the screen and scrolls sideways inside its frame. Positions are approximate by design — they are capped at about a hundred metres and describe where a named public place is, not where fish are and not a mark.
