Mike, I fished there several times - CLoser to Ouluska Pass L/T with no luck, but post this over at www.ADKForum.com and you might find a few more sportsmen that have fished that area.
When I did a thru hike of the Northville Placid Trail a couple of years ago, I did some fishing up Cold River. I didn’t have any luck there except in the pool directly below Duck Hole dam, but this was the only time I’ve fished there.
