Frivolous question but - I was told once that the definition of a lake was
that it covered an acre of land. In discussing this with someone, I saw an
internet definition giving 0.25 of a hectare as a lake. Anyone got any
other ideas/sources/definitions?

I suspect the 'eye of the beholder' might have some bearing.
