The Beaverkill has been rising due to consistent rain showers these past few days; although the upper Beaverkill is at a normal/slightly lower flow than average for this date, the lower Beaverkill at Cooks Falls has risen to almost 1200 cubic feet per second, which is more than double the average flow of 503 cfs on May 24 over 99 years of record-keeping.
There have been sporadic hatches from morning until dark of a variety of flies; caddis, mayflies and stoneflies. Fishing can be productive all through the day. This is the time of year that fly fishers anticipate, with a number of hatches that can occur at almost any time – and it’s a good idea to have an assortment of flies to choose from.
In addition to various sizes of caddis flies and a few remaining Hendricksons, there are reports of March Browns on the water. These are large (size #12) mayflies that hatch in the afternoons. Gray Foxes are around in the afternoons as well, and Blue Winged Olives have been coming off the water during the day. There have been reports of a few Green Drakes on the lower river.
When flies are hatching or on the water, try to match the size, shape and color. And when no flies are hatching, use attractor flies such as a Royal Wulff, to spur on some activity. Favorite Beaverkill flies to use for this time of year include the Elk Hair Caddis in a size #14 and the Adams in sizes #14, #16 and #18.
In high and discolored water, a large streamer, such as a Black Leech, can be productive.
