There used to be a few springers in the satsop back in the day.How I know this, is I almost went on a guided trip there for them in the late 80's early 90's,but our original plan came thru so we didn't have to end up there,but it was an option @ that time.Not gonna mention the guides name as he's a good one and still guides to this day,just not for springers on the satsop.Good luck,

Like drifter mentioned,they most likely were netted out.
