Check out local guide/writer/blogger Steve Culton's article on the Farmington River in the latest issue of Eastern Fly Fishing- there's even a big picture of yours truly in the article, but check it out anyways...:)
The low light periods of dawn & dusk are typically the best streamer bites, but overcast days are good and as we get further into Fall the bite can often be good all day as trout aggression ramps up. Try different size flies. Yes, on average, bigger flies will catch bigger fish, but some days the trout (even the bigger ones) don't want big flies. Or try a two-fly rig, with either a smaller, unweighted streamer or a nymph behind a weight streamer- this will get you some of those trout that move for your bigger streamer but won't eat it. In lower flows like we've been having a floating line with a weighted streamer will get you deep enough, but if flows are medium to high you may want to use some sort of sinking line or leader to get your fly deeper. Use heavy enough tippets so that you don't break off fish on the strike- I typically go 0x on my bigger streamers (you can go even heavier with really big flies), and even on average sized ones (#6-8) I wouldn't go below about 2-3x as trout hit streamers HARD. You can fish normal ize streamers on your #4-5 rods for sure, but.... a #6-7 rod with a medium-fast to fast action will do a better job casting, setting the hook, playing bigger fish, and throwing bigger flies.
As of September 1st, the entire Farmington River from the dam in Riverton for 21 miles downstream to the Rt 179 bridge in Unionville is now Catch & Release until Opening Day in April 2020. If you see anybody keeping fish in this section, please call the CT DEEP at 1-800-824-HELP and report the violation. Even if they are not able to respond to it on time, the info goes into their database and helps to create better/more policing of the area in the future.
Dry/Dropper can be a fun way to fish as long as water temps are 50 degrees or higher (I'd do mainly in the afternoons), and there are decent hatches: use a bigger buoyant dry (like a Mini Chernobyl, Chubby Chernobyl, etc.) and drop a #16-18 tungsten bead nymph 1-3' below the dry. Most fish will take the nymph, but you will get some bonus fish on the dry also. Tie the nymph off the hook bend. Run it closer (12-18") to the dry during insect activity/hatches or in shallow water, run it further apart (2-3') in deep water and during non-hatch periods. It's like the fun of dry fly fishing, combined with the consistent effectiveness of nymphing. Plus it allows you target fish at distance and not spook them. If you wanna target big trout on the surface after dark, try a short/heavy 6-7.5' leader (0x) with a deer hair mouse pattern- make sure to bring a BIG landing net with you...:)
Zach St. Amand, one of the top local guides and frequent flyer in our big fish pictures, is leading a trip with Andes Drifters to Patagonia for big wild trout, February 8-15th 2019. He still has some availability, call him at 646-641-5618 to find out more or to get onboard.
From April through October we are open 7 days a week, 8am to 6pm Monday through Friday, and 6am-5pm on weekends (this will be pared back to 8am-5pm 7 days a week in November).
