The Owendoher River (Irish:An Dothra Bheag, i.e. "The Little Dodder") is a small river in southern County Dublin, Ireland, the largest tributary of the River Dodder, and a part of the River Liffey system.
Course
The Owendoher rises in two main branches. The larger branch flows from Glendoo / Glencullen valley, and meets the second, in turn formed from two streams, one sometimes called Kilakee Stream, from the slopes of Killakee Mountain, and the other Glendoo Stream, from west of Glendoo Mountain. The two branches merge near Rockbrook Cemetery, along with another small stream from Woodbrook and Piperstown, and the Owendoher flows north to Ballyboden, and on to Rathfarnham, receiving the Whitechurch Stream.
The Owendoher joins the River Dodder south of Bushy Park near the former settlement of Butterfield, just south west of Rathfarnham village.[1][2]
There were historically a number of mills on the Owendoher and its tributaries; none now operate.
Bridges
As the Owendoher now passes, in its lower reaches, through heavily developed areas, it features many bridges - from where the river joins with the River Dodder to its source in the south:
