The ct river coves can be good for panfish, and you can catch walleye once in a blue moon. Don't go expecting to get walleye, but you can get bass, pike, catfish, bowfin, stripers, and pretty much everything else that swims in CT waters. If you want to target walleye the closest lake is Coventry Lake. It's less than 20 minutes away and has great action for perch and walleye. Most of the walleye are small, 14-18", but there are some bigger ones in there. If you want to go to one of the lakes that produce bigger fish you'll have to drive a lot further.
