- When Rainfall is too great, the flow direction reverses for the main part, dumping its contents into the Corrib River.
- Two narrow foot Bridges exist near both "holes" - for human convenience, I presume, and not wide enough for the usual Cattle populations, there.
- You don't really see a hole - you can see the Water heading somewhere - you can hear it . It wouldn't pull a Boat down or anything dramatic to that degree.
- At these points, the elevation is maybe, 2 metres, with the hinterland funneling anything responsive to gravity, into it.
- What is dramatic enough, is the alignment of boundary walls, above it. Presumably, this was a Drainage measure and is clearer in the old Maps. The Fields are long and thin - more structured than most places.
- The Castle in Castlegar Village was historically, the closest structure to the East. ,
