The Beaverkill at Cooks Falls was recorded as flowing at 174 cubic feet per second on Wednesday afternoon, July 20. This is above the average flow of 150 cfs over 102 years of record-keeping. Water levels have been above the average flow over the past week, thanks to the numerous rain showers and storms, and fortunately we have enjoyed some cooler evenings as well - and so the water temperatures remain favorable for trout.
Good fishing has been reported in the mornings and evenings, with smaller Trichos and small Blue-Winged Olives in the mornings, along with various sizes of caddis flies. By late afternoon there may still be some dark-colored Isonychia (a Dun Variant in size #14 works well during this hatch) and the lighter-colored Sulphurs mixed in. Mid-summer is a great time to use terriestrials, such as ants, beetles, grasshoppers and inchworms, especially along a streamside-log or below overhanging branches. Observe the water before you enter and begin to cast, as mid-summer fishing can be challenging with lower flows and spooky trout. A favorite fly in the faster water is the Elk Hair Caddis, whose light-colored elk hair is buoyant and easily seen.
The West Branch Delaware River has held its level steadily between 550 and 600 cubic feet per second all week, thanks to bottom cold water releases, and has provided good fishing in the afternoons pretty consistently, with water temperatures varying between 48 and 58 degrees Fahrenheit since last week. Look for Isonychias, Sulphurs and Blue-Winged Olives on this river, as well as the East Branch Delaware anytime after noon.
