When studying a river from a Brook Trout fisherman's perspective, I suspect most of us tend to think in terms of rapids, riffles runs, pools, shallows, bends, water levels, obstructions and current breaks.

But what of spring holes?

Esnagami Lake provides some of the best trophy Northern Pike fishing that you will experience anywhere – and to say that they love to attack a fly is perhaps one of the greatest angling understatements of all time.
