I don't have sufficient habitat for crawdads. The only shallow areas I have are the boat launch and a failed brook trout breeding area. Otherwise, step off the bank and its straight down. Sure, it's possible they are in there and bigfoot is feeding on them at night, but I highly doubt it. Sasquatch are vegetarians.

There is a reason every state in the US regulates crawdads, native or non-native, as do most industrialized countries in the world.
