I had the good fortune to fish the Wood River today.  The Wood River is a classic spring creek in Oregon located north of Klamath Falls.  This is a challenging fishery and a must-visit fishery for dry-fly aficionados.  The mahogany mayfly hatch started around 11am and was still going strong when I had to head home around 2:30pm.  The Wood can be floated in a drift boat or pontoon boat, but I was on foot today.  I had about 3 hours of head-hunting for risers.  For the most part I had to stay low and sit or kneel while fishing to avoid spooking the fish.  I saw some fish that were in the 18" range rising regularly, but they were very smart.  I landed several fish in the 10-15" range on dries today.  All but one were brown trout and every single fish jumped multiple times.  If you like technical dry fly fishing you should book a trip on this river with one of the regular guides up here.  It's pretty sweet.  Summer is hopper time and spring and fall is mayfly time.
