Course

Main course

The Ballyboghil rises around Tobergregan, south of Garristown in the extreme northwest of Fingal and the traditional County Dublin. It curves southeast near a cemetery in the townland of Grallagh, and continues to Brownscross. At Westpalstown it receives the tributary Daws River, which has come by way of the hamlet of Oldtown. The river flows on to and through the village for which it is named, Ballyboughal, itself named for a holy staff associated with St Patrick. Richardstown River flows into the Ballyboghil near the site of the school and nunnery of Grace Dieu, and a channel takes some of the flow of the river south to the Turvey River. As it approaches its estuary, the river flows under Daws Bridge, and then as it widens into the estuary, the Corduff River, also known as the Ballough Stream, and once also the Nine-Stream River, joins.

Rogerstown Estuary

The Ballyboghil and Corduff combined flow is the main supply to the 4.5 km-long Rogerstown Estuary, into which Balleally Stream, Bride's Stream, Jone's Stream and two small streams flow. The estuary is bisected by the Dublin-Belfast railway. 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.

Flora and fauna

The Ballyboghil holds both brown and sea trout, as well as eels and Atlantic salmon. The Ballough also holds trout and salmon.
