Source of the Delgany Stream is about here and it flows just inside (East side) Bellevue Hill Road then turns East along field ditch into Carmelite Monastery Walled Garden then South and underground under Convent Rd down the hill under village centre emerging in back garden of the Old Rectory, out under (and over when flooded) Priory Road and into Three Trouts Stream just south of the bridge on Priory Rd

Brown Trouts Stream (Castle Stream branch) rises here in Old Bellevue Estate close to Sheila's Well, flows South East, joins with the other (Mill Stream) branch south west of Kindlestown Castle, down Delgany Wood and joins Three Trouts Stream on the Archers Wood Estate close to Evans motors
