The HEX hatch is in full swing. Find a lakeside, white birch tree and shake it sometime just after noon and watch what falls out. The notorious Hex hatch is one of the most coveted hatch for fly fisherman. Big trout will feast on this big bug throughout all of its life stages. Primarily found on lakes and ponds, the Hexagenia Hatch starts around the end of June and finishes up around the 15th of July. Tonight throughout the remainder of this upcoming weekend you will find me in my Kayak, fly rod in hand waiting for this hatch to occur.
