In the upper and middle reaches, lightly weighted stoneflies and mayfly patterns such as Pheasantail, Halfbacks and Hare and Copper in sizes 14 to 18.
Popular patterns include Royal Wulff, Adams, Blue Dun, Coch-y-Bondhu, green beetle patterns (during the early summer), and cicada and cricket patterns late in the summer.
Wet flies / Streamers:
Small bully patterns such as Mrs Simpson and Hamill's Killer during the day and dark patterns such as Craig's Night-time and Scotch Poacher during the evening and at night. In the middle and upper reaches use small wee-wets such as March Brown, Greenwell's Glory, Red Governor and Hardies Favourite during the evening rise when fish are often taking emerging insects just subsurface.
Black and gold Tobys and silver Tobys in the lower reaches, and small bladed spinners such as Mepps or Veltic in the middle and upper reaches. As this is a rainbow fishery, brighter colours such as gold and red tend to work well during the day.
