Lambroughton Loch or Wheatrig Loch was situated in a low lying area between the farms and dwellings of Hillhead, Lambroughton, Wheatrig, Titwood and Lochridge mainly in the Parish of Dreghorn, North Ayrshire. The loch was mainly fed by the Lochridge (previously Lochrig) Burn, the Garrier Burn and surface runoff, such as from the old rig and furrows indicated by Roy's Maps of the mid 18th century. The loch outflow was via the Lochridge Burn that runs into the Garrier Burn, passes the site of the old Lochend habitation and into the Bracken Burn near Little Alton.
