The Beaverkill is very low, as are most all of our Catskill streams, due to a lack of significant rain since the beginning of autumn. However, the cooler evenings have helped to keep water temperatures favorable, heading into these last two weeks of the regular trout fishing season.
There have been reports of good hatches of dark caddis flies and a few Isonychias (mayflies) during the afternoon and into the early evening. In addition, watch for hatches of Blue Winged Olives, especially after a frost.
Dry fly fishers might switch to slightly longer leaders, and making more careful casts to keep water disturbance to a minimum.
Autumn is a good time to fish with terrestrials such as ants, beetles and hoppers, as well as caddis flies and Isoychia imitations. However, late-season trout fishers may find that streamers, such as the Black Ghost, Mickey Finn, Black Leech and Muddler Minnow might be effective, especially with the young-of-the-year fingerlings now present in the riffle areas. Other flies used during fall fishing include Beadhead nymphs, a Black Leech or Woolly Bugger.
Don’t forget that you’ll need to purchase a new fishing license, as the license year began on October 1, and will run through September 30 of 2014.
