Small – Likely catch is less than 14 inches
Medium – Likely catch is 12 – 18 inches

Few – You’ll have to work to find and catch fish
Some – With proper technique, you’ll find a good amount of fish
Many – There are a ton of fish in nearly every spot of the river

POPULARITY
Low – There are few to no people when you fish. Weekends you’ll only see a few people at most with plenty of room to fish.
Medium – There are a few people and you still have room to fish, but you won’t find complete solitude. On weekends you’ll have some company, but won’t feel crowded.
High – There are people fishing here every day and even at night sometimes. During the weekends, it’s a social setting as much as it is a fishing location.

RIVER TYPE

Tailwater – The water below a reservoir dam
