Phishprheak, Goat Lake WAS planted with Atlantic Salmon which dined on the scuds and bacame big up to around #5-6. It was well known among the Olympics fishing/hiking fraternity back in the late 70's and 80's. I doubt the plants were continued,last I heard there were no more Atlantics. But like you say it does get planted once in a while w/bows.
Don't worry about me or any other guys getting in there and depleting it. By the time anyone finds the maps that show it,hike up the mountains a long hike,etc. they'll be ready to head for home with just the experience to show for it.
