Drumaleague Lough (Irish: Droim Dhá Liag Loch, meaning 'lake of the ridge of the two stones')[2] is a very small freshwater lake in County Leitrim, Ireland.

[8] A, the central oblong portion, consists of a platform of round logs cut in lengths of 1.2m to 1.8m, possibly the floor of the hut ; B, a collection of stones with marks of fire on them ; C, a heap of stiff clay; D, the root of a large tree nearly buried in the peat, the surface of the wood bevelled off, so as to form a sort of table, under which was found a considerable quantity of bones, apparently those of deer and swine.

The annexed section conveys a good example of the flooring of an oblong house for this type of crannog, surrounded by a regular circular enclosure formed of a single row of oak stakes F, F; and being 22 metres (72.2 ft) in diameter.

[8] G, the lower stratum of decayed and blackened sticks and branches of all descriptions lying in every direction : this layer extended as far as it was pierced in the examination, viz., about 1.2 cm, but was evidently of greater depth.

[10][n 1] The recording of large numbers of ancient dug-out canoes found in County Leitrim remind us that waterways also provided a key means of transport both before and since the Middle Ages.
