The Deerfield River Fly Fishing Report for 7/15/2020: Our local tailwaters have been producing excellent fishing. My guided fly fishing trips on the Swift River have been producing double digits practically every trip. In house nymph patterns have been doing the most damage over there- think terrestrials fished on top and subsurface. The Deerfield has been best in the evening and after dark. The rain has brought a resurgence of insect activity-small sulphurs (16), small tan caddis (18-20), small black caddis (18-20) can be in the mix as well as big Iso’s (slate grey drake) 10-12. The sulphurs have been making appearances on the Swift too-(16-18) This activity for the most part is end of day, night, and first light. Midday has been better for swimming. I’ve been structuring my trips to address this typical summer pattern-early morning half days and evening half day trips are the most productive. It will stay this way until the fish start eating again midday- nothing worse than catching fish for the first four hours then nothing but a few dunks and oppressive sun for the remainder of the day. Covid is still out there so please bring masks as well as your own food and beverages. If you or someone you’ve been in contact with is sick or has been sick recently please stay home! Other than that we’re one of the lowest Covid areas in the state and we’d like to keep it that way! Best wishes for good health and productive fishing- I still have slots open in the calendar so give me a shout if you want to experience fantastic summer fly fishing!
