River Brosna and Streamstown Tributary – A Mid‑Ireland Riverside Journey

📍 County Westmeath and County Offaly, Westmeath

🏛️ Attraction

Last updated: 28 April 2026

Overview

The River Brosna (Irish: An Bhrosna) stretches 79 km through Ireland’s Midlands, rising in Lough Owel north of Mullingar and winding south‑south‑west past Mullingar, Lough Ennell, the historic town of Kilbeggan, and the villages of Clara, Ballycumber, Pullough before joining the River Shannon at Shannon Harbour near Banagher. A modest side‑stream, the Streamstown River, flows through the village of Streamstown in County Westmeath and feeds the Brosna’s lower reaches, adding a gentle ribbon of water to the landscape.

History & Background

The modern shape of the Brosna owes much to the Arterial Drainage Scheme of the late 1940s‑early 1950s, when engineers deepened and widened the channel to improve drainage across the low‑lying midlands. A 2008 diversion rerouted the river beside the N52 roundabout in Mullingar, illustrating ongoing flood‑management efforts.

Historically the river powered local industry. The Kilbeggan Distillery, Ireland’s oldest licensed whiskey distillery, still draws water from the Brosna, while the old mill at Kilbeggan bears witness to grain‑grinding wheels that once turned along its banks.

Streamstown’s own story is tied to transport. The village grew around a Midland Great Western Railway station opened in 1851, linking Athlone and Mullingar. After the line closed in 1963, the trackbed became the Old Rail Trail – a 43 km greenway that runs close to the Streamstown River, allowing walkers and cyclists to experience the waterway as part of a longer, mostly flat countryside route.

What to See & Do

Fly‑Fishing

The Brosna is prized for brown trout, salmon and grilse. Anglers launch from banks near Kilbeggan or quieter stretches downstream of Lough Ennell. Despite occasional storm‑driven sewage discharges from Mullingar, the fishery remains robust. Anglers should ensure they have a valid Irish Angling Licence and check any local restrictions before casting.

Heritage Walks & Mill Visits

A short riverside stroll in Kilbeggan brings visitors to the historic distillery mill, where interpretive signs explain the water‑wheel’s role in whiskey production. The Kilbeggan Distillery Visitor Centre offers tastings and insight into the river’s industrial legacy.

Scenic Stretches & Photography

From the clear headwaters of Lough Owel through reed‑fringed banks to the dramatic high banks created by the drainage works between Clara and Ballycumber, the Brosna offers countless photo opportunities. The quieter Streamstown stretch provides reflective water surfaces that mirror sky and cloud, perfect for contemplative moments.
