Ballyboghil River

[1] One of the larger watercourses by volume in the north County Dublin, the Ballyboghil is a salmonid river, with several species of fish, including brown trout.

It is under the responsibility of Fingal County Council, and the oversight of the Environmental Protection Agency.

The Ballyboghil rises around Tobergregan, south of Garristown in the extreme northwest of Fingal and the traditional County Dublin.

Inside the line of the rail embankment the estuary is muddy, and a large refuse facility operated for many years.

Beyond the railway the estuary continues, bends north, and then runs east and southeast out to the Irish Sea.
