The Annick Water (previously also spelled as Annack, Annoch (1791) or Annock) is the largest tributary of the River Irvine. The river runs from Long Loch, just inside East Renfrewshire, in a generally south-western direction through North Ayrshire and East Ayrshire, to confluence with its parent river at Irvine, North Ayrshire on the west coast of Scotland. The name may derive from the Gaelic for 'overflowing' and Strathannick is very much prone to flooding as recorded by SEPA. The water now (2006) appears to be pollution free for most of its length. An independent survey in the Bourtreehill (1999) area revealed a strong colony of freshwater shrimp, a crustacean known only to live in relatively clean water. On 27 January 2009 a BP tanker train carrying liquid fuels (diesel and heating oil) from Mossend to Riccarton was derailed near the bridge over the Stewarton to Kilmaurs road at Peacockbank Farm. Several wagons subsequently caught fire. The Annick Water was polluted, however, it escaped major contamination. History Mesolithic man used the Annick as his waterway. From Bourtreehill to Dreghorn, the Annick has presented us with many artifacts dating from that time. Indeed, recent archaeological evidence from Dreghorn uncovered the oldest continually used settlement in Europe. This mesolithic village was on the banks of the Annick. A number of mills existed along its length with only Cunninghamhead Mill still standing today (2006). Lambroch Mill was located near Laigh Castleton Farm. Scroaggy or Fairliecrevoch Mill was a waulk or cloth mill and existed until the 1960s, with its lade cutting across the large loop in the river near Ramstane. Downstream from Cunninghamhead was a sawmill and a corn mill existed in Perceton near the old church. Scroag or scrog is a crab apple or gnarled treestumps in old Scots and this 'nickname' well describes the area where the mill stood. A number of fords and stepping stones are present, notably at Chapeltoun, Lambroch Mill, and at Ramstane where a footbridge was also present. A footbridge is still present at Laigh Castleton and a weir existed close to Lainshaw House, raising the water level to form an area which was ideal for water fowl. A small weir is still present beneath the surviving bridge into the Lainshaw Holm. Wooden carriageway bridges existed at two places on the Lainshaw estate; the stone built abutments are still visible. A number of old bridges cross the Annick
