A century later, that geometry has largely dissolved. A reservoir was built in the vicinity at some point after the map was made, and what remains on a slight ridge is a low, poorly preserved subcircular mound measuring just over 22 by 21 metres, with faint traces of an external fosse, a defensive ditch, visible on the north-west side. The name "Moat" attached to a site like this is a common Irish placename signal pointing toward earthwork remains, often associated with Norman or medieval activity, though the precise origin and function of this particular enclosure is no longer recoverable from what survives above ground.

The mound sits approximately 30 metres south-east of a separate cairn, a type of stone monument typically prehistoric in date, which raises the possibility that the ridge was a focus for human activity across more than one period. Whether the rectilinear form visible on the 1920 Ordnance Survey map represented the original shape of the monument or a later modification is now difficult to say. The construction of the nearby reservoir has altered the landscape enough that the earlier topographical context is partially lost, leaving a site that is more gap than evidence.
