They are on now!

The Olives are on Spring Creek coming off in waves after about 12:00 noon but again you'll have to look for them, do not assume that they will come off where you are, be mobile! It does help if you have seen them in an area before but not a guarantee they will be there, I would avoid any areas below Bellefonte because of the volume of water the spring and Logan Branch bring in. Look for a good riffle coming into a long deep pool to find the best area, a small #18-20 pheasant tail nymph fished deep and left to hang in the current at the end of a drift will work well before the main hatch. When the action starts nothing works better than a emerger or a small soft hackle dead drifted into the pod of rising fish. No need to fish spinners at this time, have never encountered them during this event. Do not leave if the fish stop rising just sit tight and wait, Olives come in waves, most of the action will be over by 5:00 or a bit later.
  If you head over to Fishing Creek, be aware that the water is still up but if you want to fish use a small Chimera pupa, #16-18 bright green thorax with a black or dark brown head and get it down. I have tied a few of these with Loon UV resin on the Datum Glo Brite Floss of flour. orange for the thorax. If you get your fly down to the bottom you'll find a ton of these attached to your hook when you inspect it at this time of year, the trout love them. Any other time I would fish a flour. green thorax pattern. The Chimera is also a wonderful pattern for Penn's.
  If your on the way to Penn's nothing works better than a #12-14 golden stone fly tumbled along the bottom. But a traditional Hare's Ear tied short on a standard length hook works really well. I tie them short meaning I don't tie them to the bend because if you look at a lot of the clinger type nymphs they are all a bit short in length, do by all means use Partridge for legs on them or if your a hunter good quality wood duck works well, legs and tails are very important for this pattern. Be careful if you wade, the water on both Penn's and Fishing Creek is cold and swift.
  A word about Patagonia, I have complained to them for the last couple of years about where they get their models from, all their sleeves are longer than normal, heck I have some new base lawyers that seem to fit people who have orangutan length! They have told me that in 2019 changes will be made so normal people can find clothing that fits them and not something you have to constantly push up to be comfortable. A solid buy can be fount at Dick's, a Patagonia Better Sweater is on sale now but get their fast before your size is gone, normal pricing is $99.00 now down to below $70.00, they are the warmest piece of clothing that you can take along fishing with out adding bulk to your body, check them out.
