One more stream to add to the list is the Genesee between Wellsville and Shongo. The Wiscoy has a nice native population of Brown Trout. Oatka Creek has some terrific Sulphur Hatches and is close to Spring Brook which is a spring creek with educated native fish. I would agree with Chitown Joe the Cattaraugus Fly Shop or locally the shop is called Buffalo Outfitters has provided me with some great information. They know the waters in that area. Good group of guys at the shop.
