Spirit Lake has been closed to fishing since the mountain blew. 2 USFS biologists managed to use federal money to buy rods, reels, a boat with an illegal gas outboard motor and have "test fished" the lake for 30+ years. To date, we have seen nothing in the way of research papers from the data they claim to have a critical need to obtain.
IMO, this is a private fishing lake used by the 2 biologists at taxpayer expense.
