The Beaverkill is low, as is common during the month of August; in fact, is slightly lower than the average flow. But fortunately due to cool nights, temperatures remain favorable for the trout. The best times for fishing continue to be during the early mornings (before 11:00 am) and evenings, right up until dark.
The best trout activity seems to occur when the sun is not on the water, in the deeper pool areas and along laid-up stonewall banks during the day. In the evenings and also at dark, good numbers of trout have been seen rising, presumably to Sulphur or Light Cahills.
Tricos (size #18 or smaller) are still hatching in the mornings; as well as various caddis flies or Blue Winged Olives. During the afternoons and toward evenings, watch for Isonychias to make an appearance again, along with the lighter colored mayflies (Sulphurs and Light Cahills) that may appear in the late evenings.
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, the Elk Hair Caddis works well in the faster water, as its light colored elk hair provides buoyancy and visibility in the riffle sections. The Royal Wulff in sizes #14 and #16, and the Adams in sizes #16 and #18 are also Beaverkill favorites.
