Cooler air temperatures but warmer water temps.

It looks like the next few days on the Mckenzie will be a bit cooler. I would expect the March Brown hatch to remain strong. You may also see a few Blue Winged Olives, and a few caddis on the surface. The large caddis emergence that occurred during this past (warmer) week will be less of a factor. Nymphing will still be good, try March Brown nymphs in #12 and #14 coupled with a stonefly or mega prince. The traditional wet fly swing should really be productive under the cooler, wet conditions. Try  Royal Coachman Wet #12, Hares Ear Soft Hackle #12,14, and Dark Cahill #12,14.  The Mckenzie remains in good shape and water temps are moving up,  despite the weather the outlook is good.
