Recent rains have brought the Beaverkill up to a slightly higher level than the average flow for this end-of-summer time of year, which should bode well for fly-fishers. Cool evening temperatures have kept water levels nice and cool and favorable for trout.
While the major summer hatches have finished, watch for Blue-Winged Olives and midges on the water. Terrestrials should still produce trout, especially imitations of ants and flying ants. A few Sulphurs may be about as well, and as we head into September, Isonychias will become more prevalent.
Fishing during this time of year can be productive pretty much any time of the day, from early mornings to evenings; overcast and cloudy conditions are more favorable. The best trout activity seems to occur when the sun is not on the water.
Remember to drop down in tippet size with smaller flies; use 5X for sizes #14 and #16; 6X for #16 and #18, and 7X for midges or flies in the size #20s.
When no hatches are apparent, use attractor flies, such as the Royal Wulff in sizes #14 and #16. In addition, favorite Beaverkill flies include the Adams in sizes #16 and #18 and the Elk Hair Caddis, which works well in the faster water, as its light colored elk hair provides buoyancy and visibility in the riffle sections.
