I have heard inside the bay. I had success late last year near river mouth in Cle area in November. Jumbos but not great numbers. The Perch school and bite well in August near Catawba but most other places in Lake Erie the catch numbers are down. The Western lake Perch are generally 8-9 inches. Most everywhere else the keepers are closer to 12.
Recently a near record perch came from Presqe isle area.
