Sorry Tim , No smallmouth in the last 26 years of fishing the Cass chain.
Has a awesome walleye bite if you can find current in the out side mouths of the channels this time of year.
Day time bite, Don’t Laugh slow roll a White Beatle Spin in the out side weed lines and secondary breaks along the coon tail and cabbage.
Cass lake weed line Walleyes at its finest.
Hope this helps & Good luck
TK
