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 and destroyed in the Reformation period.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. The Corduff, in turn and as indicated by one of its alternative names, has many small tributaries.
