Boomer's Reservoir
Reservoir · Fresh water · in Northern Ireland
A deep, 15-hectare rainbow trout reservoir off Derriaghy Road on the edge of Lisburn, fly only, with bank fishing round much of it and seating in several places.
Safety: cold water shock — can cause serious injury or death (general advice, not specific to this place). 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
- Regular local target
- Fishing sources describe this as a normal local target here, not merely as caught.
- 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 Boomer's Reservoir 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.

Also documented at neighbouring places
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.

- Tench — documented at Tullygiven Lough; Enagh Lough, Caledon
- Common carp — documented at Cypress Pond, Castlewellan
- Gudgeon — documented at River Lagan at Stranmillis
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.

Getting there
What public sources describe, last checked 2026-10-24. Car parks fill, services change and a path existing is not a path anybody may use — none of this is a guarantee of availability and none of it is permission to be anywhere.
- Getting to it
- From Lisburn, take Derriaghy Road and turn onto Linen Green. Tickets must be booked before you go.

Open all year, DAERA's page says.
Safety
Cold water shock — Can cause serious injury or death
General safety for this kind of ground, not a finding about this place.
Water around these islands stays cold enough all year to trigger cold water shock — involuntary gasping and hyperventilation on sudden immersion, which can cause somebody to inhale water in the first seconds regardless of swimming ability.
What reduces it: Wear a buoyancy aid where immersion is credible. If immersed, float on your back until the initial response passes rather than trying to swim immediately.
Drowning and immersion — Can cause injury needing treatment
DAERA describes a deep reservoir with steep drop-offs along the shore; wading is prohibited, and the dam wall is not to be fished when it is damp or wet.
What reduces it: Fish from the bank without wading, and stay off the dam wall in wet weather.
Rules and access
Licence
A rod licence is required, and Northern Ireland has two licensing authorities — DAERA and the Loughs Agency — covering different areas. Which one issues yours depends on where you are fishing.
Permission to fish
Separate, and both are needed. A rod licence plus a permit or day ticket for the specific water is the normal requirement here.
Particular to this water: DAERA's page, read on 24 October 2026, opens this water all year and requires a DAERA game rod licence from age 12 and Lisburn Angling Club's day ticket, which is limited to DAERA game season permit holders and members' guests and must be booked in advance. Fly only, barbless or de-barbed hooks, and no floating flies on a sinking line. One rainbow trout a day over 30 cm, then catch and release; fish over 3 lb go back. No wading. DAERA's page says the ground does not suit disabled anglers.
Beyond what is stated above, 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.
Who holds the answer:
- 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, for inland fisheries administration, rod licences and public angling permits across most of the jurisdiction.
- The cross-border loughs agency, which administers fisheries in the Foyle catchment and the Carlingford area across the frontier, and issues its own licences for those areas.
- The club, association, estate or private owner controlling the water, where the fishery is not publicly administered.
- The authority managing any marine protected area, area of special scientific interest or designated site, Strangford Lough in particular.
- Lisburn Angling Club, which manages the fishing on this DAERA-owned water under an agreement with the Department and sells the visitor's ticket; a DAERA rod licence is needed as well.
