The last couple of years, the striper fishing in Maine has been poor.
Hopefully this season will be better.
There's a resident population out of Merrymeeting Bay, but the migrant fish are not making it that far up the coast.
A couple of books that may interest you are Ed Mitchell's Fly Rodding the Coast and Lou Tabory's Inshore Fly Fishing
