Today, if you were to stand in the same spot, you would find no lake at all, only wet, marshy ground, and somewhere within it a low, oval rise in the earth measuring roughly fifteen metres by ten. That modest hump is what remains of a possible crannog, an artificial or partially artificial island of the kind built and inhabited in Ireland from the Bronze Age through to the early modern period, typically constructed from timber, peat, and brushwood to provide a defensible or simply practical dwelling place on water.

The lake itself has been drained since those nineteenth-century maps were made, shrinking from an open body of water to a waterlogged field. The slight elevation that once formed an island now sits close to what would have been the southern shoreline after drainage altered the landscape. No archaeological features have been identified on the raised area, which means the crannog classification remains tentative. It is possible that whatever structures or deposits once existed here were disturbed or lost during the drainage works, or that the mound was always a natural feature that happened to resemble the man-made islands so common across the Irish midlands and west.
