River Eske

Overview

The River Eske (Irish: An Easca) begins its 5 km journey at the tranquil Lough Eske in the south‑eastern part of County Donegal. From the lake it winds westward through the foothills of the Bluestack Mountains, picks up the Drumenny Burn near the Community Hospital, and then threads its way through the historic streets of Donegal Town before emptying into Donegal Bay at the harbour.

The river is a magnet for anglers – its waters host spring salmon, sea trout, char and a healthy brown‑trout population. The fishing season runs from 1 March to 30 September, with the most productive runs of salmon and sea trout occurring in the summer months.

Beyond sport, the Eske provides a scenic promenade for walkers, a series of striking bridges that chart the town’s development, and a dramatic setting for the 15th‑century Donegal Castle, which crowns a bend in the river near its mouth.

History & Background

Historically the Eske has been the lifeblood of Donegal Town. Its banks have witnessed the rise of the O’Donnell clan, the construction of Donegal Castle in 1474, and the later English occupation that saw the nearby Franciscan Abbey destroyed after the Flight of the Earls in 1607.

The river’s bridges tell a parallel story of engineering and community. The first crossing, Lough Eske Bridge, appears almost immediately downstream of the lake. Further downstream lies the 19th‑century Thrushbank Bridge, followed by a modern concrete span on the N56 bypass. Inside the town the river is crossed three times: Kennedy Bridge (erected 2004 on a site used since the 1830s), the iron‑clad Tyrconnell Bridge – originally built in 1895 and substantially rebuilt in 2018‑19 – and the historic three‑arched Bridge Street crossing, listed on the Record of Protected Structures since 2003.

The Lost Six‑Arch Bridge

Older maps and a 19th‑century lithographic print reveal that before the present three‑arch stone bridge a six‑arch bridge stood just north‑east of the current structure. Samuel Lewis’s early‑1800s topographical work and the 1837 six‑inch Ordnance Survey map both show a “tolerable bridge of six arches” carrying the main road behind Donegal Castle, linking Bridge Street to what was then known as Bridge End (now Meetinghouse Street). The National Inventory of Architectural Heritage records that the current three‑arch bridge was built c. 1855, replacing the earlier six‑arch bridge which co‑existed with it for a short period around 1860. The older bridge likely replaced an even earlier crossing dating to the pre‑1700 era.

What to See & Do

Angling

The Eske is a premier salmon‑and‑trout fishery. Anglers favour sections such as Timony’s Turn to the Mill Pool, the stretch below Miss Jenny’s Bridge, and the Eel Weir Turn downstream of Lough Eske Bridge. Both fly‑fishing and spinning are popular, with flies like the Fiery Brown, Jacob’s Ladder and Donegal Blue proving effective.

A permit is mandatory (see Practical Information). The river offers wheelchair‑friendly access at the Mill Pool, making it one of the few inclusive angling sites in the region.

Walking & Heritage

The Bank Walk follows the western bank of the Eske for roughly 2 km as it approaches the bay. This tree‑lined path is dotted with whimsical “fairy doors” that delight children and adults alike. From the walk you can glimpse the ruins of the Old Abbey (Donegal Friary) on the opposite bank, founded in 1474, and enjoy panoramic views of Donegal Castle perched on a river bend. The walk is fully paved near the Mill Pool and provides easy access for families and wheelchair users.

Photography & Scenic Views

Photographers will appreciate the river’s changing moods – from the gentle ripples near Lough Eske to the brisk currents as it rushes under the historic bridges. Sunset over the estuary paints the castle’s stone walls in gold, while the surrounding Bluestack Mountains provide a dramatic backdrop.

Wildlife & Birdwatching

The Eske supports a healthy fish community – salmon, sea trout, char and brown trout – which in turn attracts a range of birdlife. Kingfishers are frequently seen darting over the shallows, while grey herons and ospreys patrol the estuary during migration season. Otters have been reported along quieter stretches, making early‑morning walks a good chance to spot Ireland’s shy mammals.

Recent Environmental Incidents

• Oil spill (June 2024) – A noticeable oil sheen was reported flowing down the Eske into Donegal Bay, prompting an assessment team to investigate. Local authorities warned of potential impacts on fish and other marine life. Visitors are advised to check the Donegal County Council website for any water‑quality advisories before planning a swim or a close‑up wildlife walk.
• Flood risk – The river has a history of rapid rise during heavy rain. In October 2019 the town faced high‑tide flooding after Storm Lorenzo, with roads such as the Quay Car Park and Old Laghey Road affected. During the fishing season, especially after prolonged rain, keep an eye on local weather updates and avoid low‑lying paths that may become water‑logged.

Seasonal Highlights

• Spring (March–May) – Early salmon runs begin, offering the first opportunities for anglers and a burst of activity among river birds.
• Summer (June–August) – Peak salmon and sea‑trout runs; the river is at its busiest, and the long daylight hours make walking and photography especially rewarding.
• Autumn (September) – The final salmon run and the start of the fishing season’s close; colours along the banks turn golden, providing striking landscape shots.
• Winter – While fishing is closed, the river remains accessible for peaceful walks; the misty atmosphere creates a different, contemplative experience.
