Near Hartford and West Cornwall, the Housatonic River is a fly fishing haven. Expect to find hungry rainbow trout, but picky brown trout where patience is required. The best section ranges upstream from the SR112/7 bridge near Lookout Point to downstream near the Cornwall Bridge. This 7 mile stretch, the Cornwall Trout Management Area is an excellent trout stream passing through a rural farming valley. With patience, you may find some 18" wild trout.
There is a 10 mile long trout management area that begins near SR112 and SR7. It runs downstream to SR7 near SR4. Many consider this to be the best section for fly fishing. There are long, deep slow pools.
The 3 mile Kent Trout Management Area is also productive.
Note: the upstream dam has some unscheduled dam releases which can wreck havoc with local fly fisherman.
Overall, Housatonic River is the 3rd most popular fly fishing river of all 3 fly fishing spots in Connecticut.
