The River Camac (sometimes spelled Cammock, or, historically, Cammoge or Cammoke; Irish: An Chamóg or Abhainn na Camóige) is one of the larger rivers in Dublin and was one of four tributaries of the Liffey critical to the early development of the city.
The Camac forms from a flow from Mount Seskin southeast of Saggart, to the southwest of Dublin city, and other mountain streams, as well as an 18th-century diversion from the Brittas River tributary of the River Liffey.
It flows through a mountain valley, the Slade of Saggart, southwest of the broad Tallaght area and east of Newcastle, then past Saggart, through Kingswood and under the N7. The Camac proceeds through Kilmatead, where there is a small lake with islands, and from there flows into Corkagh Park (formerly Corkagh demesene) where the river was diverted into numerous ponds over the centuries that provided water for local mills. There are two ponds at the back of Kilmatead, a new fishery pond in Corkagh Park, the dry bed of a pond at the back of the Fairview Oil Mill ruins (near Cherrywood), and further downstream next to Moyle Park College where the water was used by Clondalkin paper mills in the past. Many of the concrete ponds are now in poor condition as water levels have dropped and the ponds have silted up. The Mill pond (Leinster Paper mills) was situated on old Nangor Road, but was unfortunately covered to make way for a car park and entrance for the Mill Shopping Centre from the Nangor Road side.
The Camac then flows through Clondalkin village opposite the Garda Station, down Watery Lane, and goes on to Inchicore, where it is tunnelled under the Grand Canal before a bridge crossing at Golden Bridge, and Kilmainham, where it runs behind the jail museum, before entering the Liffey alongside Heuston Station, a little upstream of Sean Heuston Bridge. The river was culverted underneath the railway station when it was built in 1846.
The Camac receives tributaries in the Slade of Saggart, including the Ferny Glinn and the Two Slades, and later from around Newcastle, and near Clondalkin (including the Boherboy, Brownsbarn and Fettercairn Streams, the latter joining near the boundary of Corkagh Park, in which the Camac features). Lower tributaries include the Robinhood Stream (Coolfan River), Gallblack Stream (formed from the Blackditch and Gallanstown Streams), Drimnagh Castle (or Bluebell) Stream, and Walkinstown Stream.
