Acidification[eedit | eedit soorce]

By 1800 the watter o Loch Enoch haed awready become acidic.[3] J. McBain in his 1929 beuk The Merrick and the Neighbouring Hills - Tramps by Hill, Stream and Loch descrieves a troot 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 recordit troot catcht wis in 1899. Syne 1940 the loch becam mair acidic acause o acid rain[3] an in the 1950s it completely tyne't its fish population.[5] In 1994 it wis restockit wi 3,000 troot.[4] The loch haesna become mair acidic syne the mid-1970s an haes become a wee nae sae acidic fae the 1980s onwart,[1] wi the pH increasin slaw fae aroond 4.3 in 1978 tae 4.9 in 2003.[6] Atween 1983 an 2003 the loch's Dissowle't Organic Caurbon levels increased.[7]
