I'M right now tying patterns for my trip next week over east - so am going through some "theories" on patterns and water clarity. bakerite informed me that right now there is only 4 to 5 feet visibility in the lake. now from when I fished it in the spring (very clear water) they did not like the white beaded chiro, but in other lakes in the region that had low visibility the fished loved the white bead chiro! I had been tying black and red nymphs and other natural colored nymphs before finding out about the "visibility" now that I have enough natural colored flies tied I now am working on brighter white beaded flies. I found that in two lakes that had super clear water they did not like the white beads and darker beads and nymphs worked much better. now in the low visibility lakes the white bead ruled hooking at least twice as many fish! My theory is that it is a (being able to see it thing) from a distance more then matching what might be hatching. black being the most visible and white being a close second I am tying red - n - black white beaded chiro's with a sparkle white shinny short tail (shuck) to help them find them better - we will see if I'm right! what might you think?????
