Three Sinn Féin MLAs have brought a motion to the newly restored Stormont Assembly for action to save Lough Neagh from its pollution crisis, as The Irish Times reports.

MLA for North Antrim, Philip McGuigan described the situation on the lough as an “ecological catastrophe”.

“The work of saving Lough Neagh and repairing the damage to its ecology and environment and that of its tributaries and surrounding land must be a top priority for the Executive in the time ahead,” he told the Assembly on Tuesday (13 February).

The motion comes on the heels of last summer’s spate of toxic blue-green algae blooms, which caused the deaths of numerous pets and was blamed for the collapse of the lough’s renowned native eel fishery.

Untreated wastewater and agricultural run-off — not to mention climate change, invasive species such as the zebra mussel, and political inaction due to the collapse of the Northern Ireland Executive — have been singled out as reasons behind the current crisis.

Warning signage is being removed from locations around Lough Neagh following this past summer’s blooms of toxic blue-green algae.

But as BBC News reports, it could be years before the ecological impact on the lough is fully understood.

Ulster Angling Federation chair Gary Houston claimed that the collapse of the Lough Neagh fly, attributed to the cyanobacteria blooms, has had a knock-on effect on all other species in the area — most notably its native trout and eels.

A spokesperson for the Northern Ireland Environment Agency (NIEA) said the fly species was not previously monitored as it was “commonplace and not a protected feature” but confirmed they are “a key trophic (food) component of the Lough Neagh ecosystem”.

“We’ve been damaging the ecosystem in Lough Neagh now for 60 years or so and we’ve been doing it knowingly for 50 years, but we’ve got away without the acute impacts [until now],” said Dr Adam Mellor of the Agri-Food and Biosciences Institution (AFBI).

All parties acknowledge that the current crisis is the result of multiple factors over decades — including climate change, changes in agriculture and the presence of invasive species — and some believe it could take just as long to turn it around.

Lough Neagh “isn’t just dying, it’s been killed” by a combination of human-made factors, one conservationist has declared as the crisis around toxic blooms of blue-green algae continues.

Speaking to The Irish Times, Friends of the Earth NI director James Orr says the situation “has literally blown people’s trust in the health of the lough out of the water”.

As previously reported on Afloat.ie, the lough — which is the source of nearly half of Northern Ireland’s drinking water — is in crisis due at least in part to the affects of pollution from untreated wastewater and agricultural run-off, as anglers and other groups have claimed.

Similar blooms of cyanobacteria have been recorded across the region, such as on the Lower Bann — which has lost at least one long-standing watersport business to the “unsustainable” situation — and with the latest confirmed at Lough Ross in Crossmaglen.

The issue prompted protestors to hold a ‘wake’ for Lough Neagh last weekend, as others lamented the collapse of the lough’s renowned eel fishery and even the Catholic and Anglican archbishops of Armagh were moved to call for immediate government intervention to help reverse “an environmental disaster”.

In recent days the SDLP has made a renewed bid to recall the Stormont assembly to address the crisis — the lack of a functioning devolved government in Northern Ireland since February 2022 being cited as one of a combination of factors that’s led to the current state of affairs.

Peter Harper of the Lough Neagh Partnership tells The Irish Times that other salient factors include the impact of the invasive Zebra mussel as well as climate change, which has raised the temperature at the bottom of the lough by one degree, in turn contributing to wetter weather that feeds the cycle of pollution from farmland and an overwhelmed sewage system.

“The lough’s in crisis,” says Ciara Laverty of the Lough Neagh Partnership. “The ecology’s changing, unless we do something drastic about it now. Decades of neglect have led us to this point.”

Causeway Coast and Glens councillors have echoed growing concerns over the state of the aquatic environment following recent blooms of toxic blue-green algae, as the Belfast Telegraph reports.

Alliance Councillor Peter McCully tabled a motion at last week’s Environmental Services Committee Meeting that emphasised the “detrimental impact these blooms have had on local businesses”.

As previously reported on Afloat.ie, at least one long-standing business on the Lower Bann has announced its closure, claiming its future is “unsustainable” given the likelihood of dangerous cyanobacteria blooms happening “on a yearly basis”.

Cllr MuCully said the response from Northern Ireland’s Department for Agriculture, Environment and Rural Affairs (DAERA) to this summer’s incidents is “not sufficient” and his motion calls for DAERA to convene cross-party talks across all affected council areas to develop and action plan.

Lough Neagh has also been affected by toxic blue-green algae blooms in recent months, with angling groups claiming that the lough is “dying” due to the affects of pollution from untreated wastewater and agricultural run-off.

The lough’s eel fishermen have added their voices to the call for action, saying their industry has collapsed this season.

"Never have I seen so many eel fisherman resorting to scale fishing in order to make some form of income,” one co-op member told the Irish News, which has more on the story HERE.

A popular destination for watersport on Northern Ireland’s North Coast has blamed governmental inaction over wastewater discharges for its decision to close after nearly three decades.

In a statement on social media, Rob Skelly of the Cranagh Activity Centre said recent blooms of toxic blue-green algae that have affected Lough Neagh and the Lower Bann are travelling out to sea through the river system, past its location.

“With this likely to happen on a yearly basis we feel that our business has become unsustainable and that we have no option but to close,” Skelly added.

He also echoed recent comments from concerned angling groups in saying that “we are seeing the collapse of the ecology of the Lough Neagh and Lower Bann system”.

Waterways Ireland advises all recreational users of the Erne System and Lower Bann Navigation that blue-green algae is present in a number of locations on these inland waterways.

Blue-green algae blooms can be toxic to humans and potentially lethal to animals under certain conditions. A number of serious incidents involving blue-green algae have been reported in Northern Ireland in recent week.

Waterways Ireland calls on all users of these waterways whether on or adjacent the water — and especially pet owners — to comply with any notices placed by their local authority and avoid contact or immersive activities in areas where blue-green algae is present.

Waterways Ireland’s jetties and slipways remain open, but the public is advised to refrain from immersive activities including swimming and not to allow pets to drink from or swim in affected areas.

The surface of slipways can become slippery due to algae build up, and Waterways Ireland advises additional caution when using slipway facilities in affected areas.

In addition, the public is encouraged to report encounters with blue-green algae blooms on the inland waterways via any of the following means:

Lough Neagh is “dying” due to the affects of pollution from untreated wastewater and agricultural run-off, angling groups have claimed.

BBC News reports on the concerns which follow recent toxic algal blooms on the lough — which has an important commercial eel fishery — and other waterways in Northern Ireland, including Lower Lough Erne.

As previously reported on Afloat.ie, three NI councils issued warnings earlier this summer following the deaths of multiple pet dogs after coming into contact with waters that had confirmed blooms of toxic blue-green algae.

But the situation goes back to at least February, where a fish kill close to Lough Neagh near Crumlin in Co Antrim is feared to have wiped out a whole year’s worth of spawning salmon and trout.

Angling club secretary Nick Hagan suggests that no one is taking responsibility for pollution of rivers that flow into the lough via untreated wastewater or alleged run-off from farms.

“The amount of slurry and raw sewage being pumped into Lough Neagh, it’s just accumulating a huge amount of nutrients,” he says. “From what I can see, the lough's dying.”

Three councils in Northern Ireland have issues warnings over the presence of toxic blue-green algae in their local waterways, as BelfastLive reports.

Fermanagh and Omagh District Council is warning people away from the water at Lough Melvin after an alarming six dogs died following visits to the area in recent days.

Another dog died after contact with the shore of Lough Neagh, where Antrim and Newtownabbey Borough Council confirmed the presence of the algae.

And Mid Ulster District Council has also identified blue-green algae in the waters of Ballyronan Marina and Battery Harbour.

The bacteria that comprise blue-green algae produce toxins that are harmful to humans and even more so to animals when ingested, inhaled or they make contact with the skin.

BelfastLive has more on the story HERE.

Waterways Ireland says it’s been notified of the presence of blue-green algae in a number of locations on the inland waterways.

Blue-green algae are toxic to humans and potentially lethal to animals.

The cross-border body for Ireland’s inland waterways asks boaters to comply with the notices placed by local authorities and avoid contact or immersive activities in areas where blue-green algae are present.

Waterways Ireland jetties and slipways remain open, but the agency advises boaters and other users to stay out of the water.

It also asks for the public to report any encounters with blue-green algal blooms to the relevant local authority.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
