Perhaps the Loch offers a more abundant food supply, or a haven safe from predators to breed, or relief from salt-water parasites (who cannot survive in fresh water). There are parallels in nature.
Not fun for long, sadly. It's highly unlikely a plesiosaur sized creature could pass undetected along the river, and certainly not through the canal. Wrt food supply, the loch actually doesn't have as much food in there as you'd think (or, to inject a bit more fun, as much as there "should be"!).

Indeed. Loch Ness is large, and is extremely deep. It actually contains more fresh water than can be found in all of England and Wales - there'd be room for an immortal creature or two to hide in there, for sure, but there's not enough room for a breeding population to go unnoticed.

You wouldn't need a camera - just knock something together. Folk will be buying cuddly toy versions of that out of Drumnadrochit within weeks.
