I think there's a couple of books on ff'ing your area, possibly one by Paul Marriner. Try searching Amazon.

Many of the same insects hatch in rivers all over the world. The main difference is timing and quantities. A general flyfishing/hatch book will be very helpful. I use one that covers the whole western U.S. then try to match up what I see for fine tuning.
