These go completely unmentioned in OED, a true JRRT original.
It’s an old concept, but a new way of putting the words together, unattested in OED as a single word or compound word.
This is a new combination word, not in the OED.
OED gives “midsummer” as on or about the summer solstice, which many will tell you is the beginning of summer, not the middle. I suppose it all depends on whether you count by light or by heat. The date can be set by the moment of solstice, or you can opt for John the Baptist’s natal feast day, June 24th. OED does not include the hyphen, just a space, so for our purposes I’m calling this a JRRT spelling.

Although I can picture and feel clearly what is meant, this word is not found in OED.
This word is not found in any form in OED.
This word does not have an OED entry, either under “low” or “seat”.
Obviously it’s a JRRT creation as a place name – but as a descriptive, it’s also not in the OED.
As a Middle-earth concept, of course, this does not appear in OED.
Note that in almost all instances “Lake-town” is the proper name of the town, well and good. But once, in 14.002, it is a word in itself a kind of town, the uncapitalized “lake-town Esgaroth”. “Lake-town” is not attested in OED.
