Hey Fossman, I don' t know exactly when, but I know it' s early in the year-March sometime. One of my uncles told me it' s lae Feb. to early Mar. You might be able to call the ODNR for more info. I normally don' t fish the walleye run, and might miss it again this year, but we' ll see. Where did you fish last year? All I' ve ever done is the Maumee at Orleans Park and a spot in Waterville once. Happy fishin to ya.
