No. I highly doubt this is a sheep dip. The drain makes a sharp turn, and I don't see any access to the water. Also, I don't think they are allowed in running water as farmers usually add chemicals.

There are cattle pens and a cattle crush there. I'm not sure how these should be mapped. Perhaps stockyard, but I hate that term for a small cattle pen or cattle crush. https://wiki.openstreetmap.org/wiki/Tag:farmyard%3Dstockyard
