I target summer flounder (fluke) here in Connecticut in the late summer, early fall.
They follow the schools of the young of the year menhaden (peanut bunker) right into the surf zone
Clousers on a floating line work for me also. I cast in front of a moving school of bait, let the fly sink, then sharply jig it back.
While the fluke are a bottom fish, they'll hit a fast moving fly at any level of the water column
