Is みなすじ a "Precedented" Reading of 水脈?


I heard the word 水脈 sung as みなすじ in a song, and I wouldn't have known what
word was actually being said if I hadn't had the lyrics present. My dictionary
doesn't show that as a possible reading, so I checked the individual kanji
readings, and while すじ is indeed the kun-yomi for 脈, みな was only listed for 水
as nanori. I wanted to ask if this reading has any precedent--that is, if
someone heard this and did not have printed lyrics handy, would they know what
word this is? Is this a reading that has been used before or regularly enough
to be associated with the word?




脈 as すじ is probably rare, but the same meaning is suggested by compound words
that use it such as 山脈, where it means a line of something.

As for みなすじ, it seems to be a word invented by the person who wrote the lyrics
as far as I can tell from google results. However it follows the rules for old
words that use 水 as a prefix: 水面｛みなも｝, 港｛みなと}, 源｛みなもと｝ 水底｛みなそこ｝.

It's not a piece of standard vocabulary, but I'd say it's definitely "wordy"
enough to use as an author.
