Black Cart

The River Cart (Scottish Gaelic: Cart) is a tributary of the River Clyde, Scotland, which it joins from the west roughly midway between the towns of Erskine and Renfrew and opposite the town of Clydebank.

The River Cart itself is very short, being formed from the confluence of the Black Cart Water (from the west) and the White Cart Water (from the south east) and is only 0.75 mile (1 km) long. The River Cart and its tributary the White Cart Water were navigable as far as the Seedhill Craigs at Paisley; and, as with the River Clyde, various improvements were made to this river navigation.

In 1840 the 0.50 mile (0.8 km) Forth and Cart Canal was opened, linking the Forth and Clyde Canal, at Whitecrook near Clydebank, to the River Clyde, opposite the mouth of the River Cart. The aim was to provide a direct link between Paisley, Port Dundas, Edinburgh, and the Firth of Forth.

The Black Cart Water originates at Castle Semple Loch in Lochwinnoch, Renfrewshire. From there, it flows northeast to Johnstone; and then under the M8 motorway at Blackstoun, where it is joined by the River Gryfe. The river then flows parallel with the main runway of Glasgow International Airport; passing under the A8 at Renfrew by means of a stone bridge, where it joins the White Cart Water.
