Loch Enoch is a multi-basin freshwater loch in Galloway, to the east of Merrick and south of Mullwharchar. The loch is situated in a granite basin and has several small islands and some beaches on its shore. The sharp granite sand of these beaches was collected and sold for sharpening knives and scythes. [2] The catchment area's vegetation is mainly Purple Moor Grass and Heather. [1]
The loch's outflow supplies Loch Doon and the River Doon, both in Ayrshire.
Acidification
By 1800 the water of Loch Enoch had already become acidic. [3] J. McBain in his 1929 book The Merrick and the Neighbouring Hills. Tramps by Hill, Stream and Loch describes a trout that 'bore the unmistakable marks of a Loch Enoch trout, i.e. it was minus the lower half of its tail and part of its ventral fins'. [4] McBain writes that the last recorded trout caught was in 1899. Since 1940 the loch became more acidic due to industrial emissions [3] and in the 1950s it completely lost its fish population. [5] In 1994 it was restocked with 3000 trout. [4] The loch has not become more acidic since the mid-1970s and has become slightly less acidic from the 1980s onwards, [1] with the pH increasing slowly from around 4.3 in 1978 to 4.9 in 2003. [6] Between 1983 and 2003 the loch's DOC levels increased. [7]
