Colorado Fly Fishing Conditions So. Platte River – 6/18/12

Monday dawned clear and hot early on. We arrived at the Trumbull – Swayback improvement area about 8:30 and wer on the rive at 9 AM. The water was gin clear, the sky was clear and the air temperature was already at 80 degrees.  From the bridge, we could see a pod of 6 fish hanging over a medium yellow sand bar at the edge of a run with moss on the bottom. They were moving around like they were feeding but nothing was coming off the water.

This pretty much summarized the trip. Low clear water, water temps in the high 40s and lethargic fish was the norm as we worked upstream to Deckers.

After lunch we went bug hunting at several places along the river.  The picture below is a good example what we found. There is one Golden Stone, I think. The most light yellow stone may have just molted and shed it previous exoskeleton. The large black stone could be a Black Stone or a Golden ready to molt. But just look at the size of that crane fly larvae. We also found a number 8 Pat’s Rubber Legs fly stuck to a log in the same area. So who says you have to fish microscopic flies on the Platte. Not so true anymore. It has taken a while but the 2002 Hayman Fire changed the So. Platte in areas from size 22 bugs to size 8 and 10 bugs.

So the next time you fish the So Platte toward Deckers, take some time to bug seine and think larger.
