Fishing crane prairie res. for 8 days last week I finally saw a cali hatch come off the last couple days. although not very a strong hatch we were able to catch a couple adults and saw that in that region the hatch was more of a light grey? Now in the start of June I will be going back to do a combo trip to East lake and crane, east lake being known for it's great cali hatch I had to make some patterns to match the regions hatch. In the new addition of flyfishing and tying journal mag Skip Morris does a write-up of the best lake mayfly hatch - THE CALLIBEATIS - good article and flies tied for each stage. but I actually like Preston's patterns better, thank you Preston for sharing!
Here is what I came up with for central Oregon lakes. I haven't come up with a dry pattern yet but will probably be an up-wing of partridge soft hackle for wings in A parachute style. most of these patterns are with partridge soft hackle. just thought I'd share!
I am confused about the colors used from different patterns? Skips patterns are both light grey and light tan? the adult I caught and viewed was light grey so my flies are all in light grey for the region. Is there something I'm missing Preston, thanks for any feed back from the masses!!!
