In the spring you can count on sauger, striper, hybrid striped bass, cat fish, carp, perch, and unfortunately Asian carp. Most of the time you can find a good spot an catch them all. Those are just the big species, you can catch more than that. Bass and bluegill will be there too. Its the best time to fish for your wide variety of fish. All can be caught as simple as a jig and grub.
