The open end of a river culvert in the bank of a much wider river, with office buildings and development visible above the waterside.
The Blackstaff emerges from a culvert at the confluence with the Lagan.

The Blackstaff River is a watercourse, a tributary of the River Lagan. It flows underneath the city of Belfast, Northern Ireland. It was formerly visible, but much of it was culverted and built over in the late 19th century.

Course[edit]

The Blackstaff rises on the slopes of Black Mountain and enters the River Lagan a short distance east of Belfast city centre. It was historically known as the Owenvarra, which comes from Irish Abhainn Bheara, meaning "river of the staffs". It is likely that this referred to a crossing made from oak beams, and that the "black" element referred to the colour of the beams.[1]

Maintenance and flooding[edit]

The Blackstaff is known as a "Designated Watercourse" and is controlled and maintained by the Department for Infrastructure's Rivers Agency. It has been cited as a main contributor to the high flood risk in central and low-lying areas of Belfast.[2] In particular on 16 August 2008, a newly opened underpass carrying the M1 motorway onto the A12 Westlink controversially flooded to a depth of 20 feet (6.1 m)[3] during heavy rain with water from the culverted Blackstaff and Clowney Rivers.[4]
