We just don't have the hatches. Fish some streamers and woolly buggers, you should catch some fish. Want to know what water temperatures to look for check out my General Information page the part titled Trout Temps. Note the best temperatures for Landlocked Salmon, it might be worth doing some fishing in Winslow near Ft. Halifax or the new Donald Carter bridge - there are landlocked salmon there.
Fishing is still good though and it is worth the cold.
Last year they stopped feeding at about 42 degrees so we don't have much time left. All this rain is coming through high and fast. But that is a good thing - the fish have been holding in the lower part of the river and this should bring them up to the dam. Also if any alewives have been holding up above the dam waiting for water to wash over the top - well they have what they have been waiting for. Water should be down and fishing up by Thursday or Friday.
