The ground and the water
- The ground
- A glacial fjord running fourteen kilometres inland between the Mourne and Cooley mountains, with a shallow bar across its mouth, deep water inside, extensive mussel and oyster ground, and a clean sand shore at Cranfield outside.
- Exposure
- The mouth takes Irish Sea swell from the south-east; the lough inside is sheltered by mountains on both sides, which also funnel the wind along its axis.
- Depth
- Deep in the fjord basin, shallow over the bar at the entrance.
- Tide and flow
- A strong stream through the constricted mouth over a bar, with an international boundary running down the middle of the water and two jurisdictions either side of it.
Through the year
Bass and ray through the warmer months, flatfish year-round, and a substantial commercial shellfish fishery in the lough.
Safety
Moving water and currents — Can cause serious injury or death
The bar at the lough mouth breaks when an Irish Sea swell meets the ebb, and the stream through the entrance is strong. The combination has taken vessels and it is close to a shore that looks benign.
What reduces it: Treat the entrance as a bar crossing requiring current local knowledge, never attempt it on an ebb against a swell, and stay clear of the mouth channel from the shore.
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.
Boat safety — Can cause serious injury or death
The lough is strewn with hundreds of rocky pladdies, many unmarked and many just covered. They show as a slick in flat calm and are invisible in the ripple that makes the fishing, and striking one at speed can hole or capsize a boat.
What reduces it: Keep to known passages, go slowly on unfamiliar water, take local knowledge of the safe routes before travelling at speed, and treat a chop as a reason to slow down rather than to press on.
Rules and access
FishingHQ does not know the current access position here. Sea angling access in Northern Ireland is governed by landowner permission, harbour and council byelaws, and fisheries and conservation measures, all of which change. Check the current position with the Department of Agriculture, Environment and Rural Affairs, the harbour or council, and the landowner before going. This water is tidal and transitional, so the freshwater regime may also apply above the tidal limit: FishingHQ does not know the current access position here. Angling in Northern Ireland generally requires both a rod licence from the relevant fisheries body and a separate permit for the water, and the two are issued by different bodies. Rules, seasons and permit arrangements change. Check with the Department of Agriculture, Environment and Rural Affairs, the Loughs Agency where relevant, and the permit issuer before going.
Particular to this water: Shellfish harvesting areas are classified for food safety and are opened and closed on monitoring results a gatherer cannot see. Neither cooking nor appearance removes a biotoxin. Check the current classification with the local authority before taking anything.
Who holds the answer:
- The Department of Agriculture, Environment and Rural Affairs, for sea fisheries and marine conservation in Northern Ireland.
- The harbour authority or council, for access to the structure or the shore.
- The Department of Agriculture, Environment and Rural Affairs, for rod licensing and fisheries regulation.
- The Loughs Agency, in the Foyle and Carlingford catchments.
- The club, association or owner that issues the permit for the water.
- The Northern Ireland department responsible for agriculture, environment and rural affairs, which administers sea fisheries measures and marine conservation here.
- The Loughs Agency or the Northern Ireland licensing body as applicable, for rod licensing and permits on freshwater and migratory fisheries, which differ by area.
- The Northern Ireland Environment Agency and the site management bodies, where a marine designation affects anchoring, access, collection or disturbance.
- The harbour authority at each port, for access to and fishing from harbour structures.
- The local district council and the Food Standards Agency framework, for shellfish harvesting area classification.
- The Loughs Agency, which is the cross-border body for the Carlingford catchment.
- The harbour authority, for navigation in the lough and its entrance.
