How big do cutthroat trout get or what is considered a big cutthroat trout cause the biggest cutthroat trout i have ever caught was 16 inches so im curious cause ive caught many much larger rainbows?

I have landed cutties up to 22 inches. I have seen them up to 24 and a half inches and rumors of over 30 inches. There are 2 main types of cutties, a sea cuttie and a fresh water cuttie. Sea runs will come into lakes following the salmon in order to eat the eggs. They are rumored to hit the salmon on the side to force out the eggs. I hope this can give you a bit more insight on this highly prized trout as I duely love chasing them down. Gang trolling is my best method sometimes up to 90 feet down.
