Black Devon
The Black Devon is a river in Scotland. It rises in the Cleish Hills,[1][2] specifically the area known as Outh Muir,[3] 1.5 kilometres (0.93 mi) north of Knockhill Racing Circuit, around 9 kilometres (5.6 mi) north-west of Dunfermline, Fife, with the gathering of three small streams in branch formation.[4] The river flows westwards through Balgonar, north of Saline, and then merges with the Saline Burn. The Black Devon flows into Clackmannanshire, through the hamlet of Forestmill and past the town of Clackmannan. The Black Devon enters the River Forth south of Alloa,[5] 1 kilometre (0.62 mi) north of Dunmore Pier.
It is a narrow and shallow river that holds wild brown trout, and also sees sea trout in winter months that come into the Firth of Forth, which is tidal as far as Stirling. The Rivers and Fisheries Trusts of Scotland manage the River Forth and its tributary rivers, which besides the Black Devon include the River Devon, River Teith, and River Allan.
Disappearance
In June 1952 the last two miles of the Black Devon disappeared[6] into old coal mine workings. These eventually filled with a mixture of fresh and salt water, the river being tidal at the point where the collapse into the mine workings occurred.
Wetland Scheme
Coal mining over a long period of time, from probably at least three collieries working different strata, had caused significant subsidence around the lower reaches of the Black Devon and its confluence with the River Forth. There was also concern about the effects of rising sea levels generally. The area between the west bank of the Black Devon and the Forth had subsided considerably and had been useful for landfill, however modern environmental considerations meant that this had to cease. Accordingly, a scheme was devised to create a wetland area.[7][8]
Gartmorn Dam
This is a reservoir which was initially built in the 18th century by John Erskine, Earl of Mar (1675–1732), and later upgraded several times by others,[9] to provide water power for the pumps which drained his collieries in Alloa. Gartmorn Dam[10][11] does not lie on the Black Devon, but is fed from it by a lade originating at a weir in the Black Devon just above Forestmill.[12] Today Gartmorn Dam is used for leisure activities. The weir and lade remain in good condition.
Other Industries
The 1956 2 1/2 inch OS map[13] shows weirs and the Linn Mill, traces of which still exist, at NS 926930 and further downstream a Woollen Mill, now obliterated by a housing estate, at NS 914923, apparently worked by water power. It is not known to what extent the various quarries and mines on either side of the river utilised water power.
