Mako Mike,
No not alewives. They're in there too, but there are smelt in West Branch Res. because Iv'e caught them through the ice, and seen them running up tribs while trout fishing in the spring. In fact the DEC stocked landlocked Salmon this year in West B. to keep the population in check. I've heard they're in East Branch too but I've never caught any. I may try w/ a sabiki rig for them this year to up the catch. USually I fish 3 ice flies on a line just under the surface w/ a lantern after dark.
Tom B,
It was just a thought. I know the Hudson used to get a pretty good run years ago and you can still take 8 qts. if you can find them. I rarely fish in CT. but I think the CT. river is an estuary, right? Anything is possible.
