Buiston Loch (NS 416 433) (locally pronounced /ˈbɪstən/), also known as Buston, Biston, and Mid Buiston was situated in the mid-Ayrshire clayland at an altitude of 90 m OD. It is visible as an often flooded surface depression in pastureland situated in a low lying area close to the A735 road between the farms and dwellings of Lochside, Buistonend and Mid-Buiston in the Parishes of Kilmaurs and Stewarton, East Ayrshire, Scotland. The loch was natural, sitting in a hollow created by glaciation. The loch waters drained via the Garrier Burn that joins the Bracken and Lochridge Burns before joining the River Irvine. It is well documented through the presence of a crannog first excavated 1880-1 and then documented by Mr. D. McNaught, Dr R. Munro and others.
