The Bella Coola River is opaque off white color in the summer from glacial flour. Last time I was there I talked with a fellow who fished for salmon, but the technique was to floss or snag them with conventional casting gear. The visibility in the water is so poor that I think the odds of a fish grabbing an artificial lure or fly is very low, and I fish for steelhead in some pretty turbid water. I've heard that some anglers go there in the spring, late April and early May before the runoff, when the river is clear, and the sea run cutthroat fishing is extremely good. The cutthroat feast on pink salmon fry as they migrate downstream.
