Our group of carpers fished Little Lake for years....the smallest I saw was about 15 lbs...mostly 18 to 22 lbs...my son caught a 25 lbr. five years ago (our last carp fishing adventure) A friend got a 30 lbr...
I miss carp'n a lot but my health failed me the past few years so it is playing with the play fish now...
No slot size for carp but you will need a licence to fish for any species...lots of luck Mate
