Origins and placenames of the Lord Sempill looking over the loch from the north
Hector Boece (1465–1536) is the first to publish a reference to the loch, using the name 'Garnoth', in his book of 1527 the 'Historia Gentis Scotorum' (History of the Scottish People), saying that
nocht unlike the Loch Doune full of fische. There is a long history of drainage schemes and farming operations in the area, with co-ordinated attempts dating from about 1691 by
Lord Sempill, followed by Colonel McDowal of Castle Sempil in 1774, James Adams of Burnfoot, and by others. Until these drainage works the two lochs nearly met and often did during flooding, to the extent that early writers such as Boece, Hollings and
Petruccio Ubaldini regarded the lochs as one, using the name 'Garnoth' or 'Garnott'. 'Loc Tancu' is seemingly the earliest recorded name from circa 1210 and the name 'Loch Tankard', 'Thankard' or 'Thankart' was used locally. A farm named 'Unthank' or 'Onthank' existed until the 19th century near to the old
Nether Mill opposite the lost 'Cairn' island and together with 'Thankard' may be derived from 'Tancu'. The term 'Garnoth' has also been used and may derive from 'Garnock'. In early feudal times many
Flemings were granted land in the valley of the Clyde, including an individual named 'Thankard', who gave his name to Tankerton, Wice in Wiston, Lambin in Lamington and William, the ancestor of the family of Douglas. A Lochend Farm existed in the area that is now occupied by Glengarnock. Early maps, circa 1600, show the two lochs with separate names, but effectively a continuous body of water. The place name 'Kerse' used for the farms and the bridge at the northern end of the loch refers in
Scots to 'Low and fertile land adjacent to a river or loch'. The old Barony of Kersland was held by the Ker (latterly Kerr) family; by chance or by association with this site the surname
Kerr may derive from the nature of the location. The term 'Loch of Kilbirnie' is sometimes found in books, on older maps, etc.
Ownership The monks of Paisley Abbey once held the lands between the Maich and Calder and it is likely that the old toll route, using the toll point of Maich, came through this area. The loch is situated in the Parish of Kilbirnie and the ancient
Barony of Glengarnock once held by the Cuninghams, a cadet branch of the
Earls of Glencairn from
Kilmaurs; it later formed part of the estate of the Crawfurds of Kilbirnie as a result of the Honourable Patrick Lindsay acquiring, in 1677, the Glengarnock estates and marrying Margaret, heiress of Sir John Crawfurd of Kilbirnie. Their son became the first
Viscount Garnock and in 1707, he had the baronies of Kilrbirnie and Glengarnock combined under into the 'Barony of Kilbirnie'. The boundary shown in 1654 between the baronies of Kilbirnie and Renfrew did not follow the Maich Water and Dubbs Water, it even ran into the loch itself, reflecting the aforementioned disputes. In 1775, Armstrong's map records 'Loch Tankard' as
the property of the Earl of Crawford, but holds of the Prince of Wales. In the 1860s, the loch was owned by James,
Earl of Glasgow. The solum of the loch is now owned by
Scottish Enterprise, however '
riparian owners' possess the loch shoreline and have certain duties and obligations as well as rights. An artificial island was created at the south-east end of the loch for nesting birds in the 1980s.
Flax and steel Lochside Farm was present on the north-west side of the loch in the 19th century, lying below and to the south-west of Lochrig, later Lochridge, as shown on the 19th century
OS map; a 'Flax Pond' for rhetting
flax, as part of the process of linen manufacture, is also shown nearby on the loch bank; it is now visible as a wet area dominated by rushes. The firm of William & James Knox, linen thread manufacturers, established as early as 1788, are still based in Kilbirnie. Scotland was amongst the first producers of flax. The road running down to the loch here from Baxter Head became known locally as the 'Shanks-McEwan Road' after the company that was contracted to remove the old steelwork's slag heaps. The Glengarnock Ironworks and the later steelworks produced slag and other wastes which were disposed of into the loch, significantly reducing its size and depth. The south-west section of the loch is still hazardous due to slag lying close to the surface. The Dubbs Water was originally dug as a canal in the late 18th century for transporting coal and iron ore to the steelworks and to take finished products to their markets. Roads were unsuitable for transport of heavy goods at the time and the railways were in their infancy.
Loch Riggs This was a collier's hamlet near the Maich Water. The Loch Riggs Colliery was abandoned in 1808, when the works were flooded. The rich coal seams ran under the loch and were never further exploited. In 1900, the old colliery waste was encountered by the navvies during the construction of the railway between Lochwinnoch and Kilbirnie. A nearby road was locally known as the 'Back-Stair-Heid' and it has been suggested that this refers to the location of a pit ladderway used to carry coal out of the mines before winding engines were in use. ==Geology==
