Should have fished more places.
Spent a fruitless couple of hours searching for a lost fly box, asking anglers fishing the pool where I last used it and checking fly shops to see if it might have been turned in - no luck. By the time I finished, the best Beaverkill pools were all filled with multiple fishermen. Drove up and down the stream using the "three rise rule" in deciding where to fish. Found a pool with six or eight fish n going, although when I got down to the stream the only things I was able to see on the water were one black midge and one large flying ant. First cast hooked a nice rainbow that tore around the pool apparently warning all the other fish because I never got to cast at another fish in the pool. Had the same experience in the other two pools I tried. The water is so low and clear that one hooked fish spooks the other fish and they stopped feeding. Tuesday and Wednesday I fished pools that normally (today for example) have numerous anglers fishing them all day long.
