The northwest part of the U.S. has a lot of rainbow trout for good eating or trophy photos to show your friends. Crappie, walleye, and bass are also pretty common and easy to catch there.
If you’re unsure about what fish are in a body of water, throw in some food scraps and wait. See what fish come to the surface. Identifying the fish is tricky when you’re starting out since you don’t know how different fish behave, but it’s something you can learn by fishing often.
