About Lough Island Reavy Dam

Lough Island Reavy is a modest‑sized reservoir created by a dam on a small river in the heart of County Down. Though the exact height and altitude of the structure are not widely published, the dam’s presence has shaped the local landscape for decades, providing water management for the surrounding countryside and creating a picturesque lake that attracts walkers, anglers, and birdwatchers alike.

History & Significance

The dam was built in the early‑to‑mid‑20th century as part of a regional effort to improve water supply and flood control for the agricultural communities around Castlewellan. Over time, the reservoir has become more than a functional piece of infrastructure—it’s now an integral part of the area’s recreational network.

Because Lough Island Reavy sits within a region famed for its glens, forests, and historic estates, the dam adds a modern contrast to the ancient scenery. Its calm waters reflect the surrounding hills and the iconic Castlewellan Forest Park, making it a favorite spot for sunrise and sunset photography.

Why It Matters

• Ecological haven: The reservoir supports a variety of fish species and provides feeding grounds for waterfowl, making it a subtle hotspot for wildlife enthusiasts.
• Recreational hub: Easy walking routes circle the lake, and the calm surface is suitable for non‑motorised boating and kayaking (where permitted).
• Cultural link: The dam ties into Castlewellan’s broader story of community development, showcasing how engineering projects can coexist with natural beauty.

Parking & Access

A small, free car park sits at the north‑east edge of the reservoir. The lot fills quickly on sunny weekends, so arriving early (before 10 am) ensures a spot. The main footpath to the lake is well‑marked and wheelchair‑accessible up to the water’s edge.
