S8, Ep 71: Fall Fishing Forecast: George Costa on Streamers, Hatches and Safety Tips

Episode OverviewGeorge Costa, manager of TCO Fly Shop in State College, Pennsylvania, returns to The Articulate Fly for another Central PA Fishing Report as the region shifts firmly into fall. Recent rain has pushed creeks across Central Pennsylvania's limestone country well above seasonal flows and off-color, but George reports everything is on the drop and should be fishable again this weekend, with cool water temperatures keeping trout active and comfortable. Fall hatch activity is picking up, with Isos (Isonychia), tan caddis and October caddis all showing well, and George notes a recent streamer bite that produced trout already colored up for fall. He and host Marvin Cash also flag a practical safety reminder: Pennsylvania's fall hunting seasons open October 1st, so anglers fishing shared public waters such as Spring Creek Canyon on state game lands should wear blaze orange. Away from the water, George runs down what's happening at TCO's shops heading into the off-season, including end-of-summer clearance pricing on Simms, Grundens and Patagonia gear, and a full slate of fall and winter fly tying and on-the-water classes across TCO's locations. Among the highlights is a class taught by Allen Rupp, Dave Whitlock's legacy tyer, covering streamer tying and the NearNuff Sculpin pattern.
