Perfect. Thank you Bozeman and Fishidiot.
FREESTONERS ALSO COME FROM SPRINGS, and the same is true of those springs, it's essentially the same temp year round.
If you were to compare the fraction of water on a freestone stream (like Slate Run) that comes from springs it would be far less than what you get from springs on a true spring creek like the Letort. Freestoners like slate run depend heavily on precipitation to maintain flows that are suitable for trout.
whereas freestone spring sources are likely to be areas of moisture saturation much closer to the surface of the land, which itself warms and cools considerably depending upon atmospheric conditions
Springs in the north country in PA flow at 48F, even when the air temperature is over 90F.
Their water temps are actually colder than the limestone springs in central PA (50F), and southcentral PA (52F).

Hmm, suspecting my thermometer reads a few degrees warm!!!! But very similar observations.
This reflects a misunderstanding of freestoners, and I don't think it is true.
