Amid concerns over reduced water levels this year on the Grand and Royal Canals, Afloat.ie reader and former Oireachtas policy advisor Cathal Murphy fears for the future of Ireland’s inland waterways

Water levels on the canals plummeted over recent months. This was seen on the Royal Canal and Grand Canal and along the latter’s Barrow Line. They were so bad in parts that boats could not move on these 200-year-old navigations.

The water levels in parts were allegedly down over half a metre, the lowest in living memory. These historic pieces of heritage are under threat because if water levels continue to decrease they will not survive.

Is it structural problems? Is climate change responsible? The answers are yet to be found. The canals are supposed to have a stable water level, they are supplied off feeders which are water sources redirected from rivers.

These canals are great pieces of engineering, naturally maintaining their levels for boats to navigate. But suddenly after two centuries of functional infrastructure, we are seeing boats halted as water levels shrink.

The State at the moment is putting millions into greenway and blueway routes along these canals, but without the water and the boats these will become just paths along empty trenches in the countryside. It should be a basic function to keep water levels up as has been done for the past 200 years.

It is not just the heritage affected. These waterways maintain immense biodiversity. Low water levels increase algal blooms, with devastating effects on fish and other invertebrates that use the habitat of the canal.

There is huge cultural and historical importance to the canals, forming a network upon which nature flourishes, history is functioning and people travel. Ireland needs them. They encourage tourism from both home and abroad so people can navigate these waterways like the canals of England and France.

Waterways Ireland, who maintain the canals, have said previously that low levels are due to leaks and not enough machinery to maintain the feeders that supply the canal, and maintain canal navigation.

Although this year we have seen some of the lowest levels, this has been an ongoing issue for a decade. This year marine notices stated that water levels were down 45cm in late August, and anecdotally they were down 60cm from Monastarevin to Athy along the Barrow Line.

The drying up of our canals is happening in front of our eyes. Some interim measures have been taken that have seen a rise in water levels in recent weeks but these are not long-term.

Whatever the reason for the water disappearing, the canals need to be protected, and to be seen as the asset of the State that they really are — and an amenity to all.

Waterways Ireland advises masters and owners of vessels that low water levels are being experienced on the 26th level (Long Level) of the Grand Canal’s Barrow Line.

As of Friday 30 July, water levels are down 400mm from expected levels. As a result, masters of vessels are advised to proceed with additional caution and to contact the water patroller (Joe Moore at 087 247 3093) for latest advice and assistance.

Waterways Ireland advises masters and owners of vessels that due to technical difficulties, the lifting bridge on the Grand Canal’s Barrow Line at Monasterevin cannot currently be opened for navigation traffic.

Staff are working to put the bridge back in operation, and the cross-border body for Ireland’s inland waterways says it hopes to issue an update by the coming weekend.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
