Lots of comments on this body of water! First let's admit Most people fish Walleyes to EAT!Almost ALL waters in SE Wi. Are put and take Walleye fisheries! How much natural reproduction on Kosh is a crap shoot!Since the Hatchery is back millions of fish,fry and fingerling have been stocked in the system!Anyone that fishes the system knows in the Rock the fish come up in waves,some days the river is full at certain places and catches are plentiful a day later gone! Just look at this spring! Cell phones and ( catching reports) contribute to massive number of fishermen!Many comments that they are runing the fishery,well license fees are enabling the fishery!If a 5 fish limit can't substain  the stocking program the the dnr should drop it to 3 or raise stocking numbers!Slot limits seem to work,why the are not used here seem to indicate natural reproduction is not to good on this system!Closing the system in spring is NOT the answer!
