About Lough Island Reavy Dam

A Brief Description

Lough Island Reavy Dam is a small reservoir dam located at coordinates 54.237028, -6.020814. The structure creates the serene Lough Island Reavy, a lake that reflects the rolling hills and woodlands of the Castlewellan area. While the exact height and altitude of the dam are not publicly documented, its modest scale makes it an ideal spot for leisurely walks and picnics rather than extreme adventure sports.

History & Significance

The dam’s origins trace back to the early 20th century, when local authorities sought to secure a reliable water source for agricultural use and the nearby community. Over time, the reservoir evolved into a recreational asset, attracting anglers, birdwatchers, and families seeking a quiet day out. Its presence also contributes to the region’s biodiversity, supporting aquatic plants, fish species, and a variety of waterfowl.

Why It Matters

• Ecological value: The lake serves as a habitat for native fish and migratory birds, making it a subtle but important piece of County Down’s ecosystem.
• Cultural relevance: As part of Castlewellan’s rural heritage, the dam reflects the historical relationship between the community and its natural resources.
