How do you know where a fish is in the water?
Find irregularities along edges that concentrate fish. Look for the tip of a long point extending into the lake, where it suddenly drops off into deeper water. The general edge of weeds attract fish. Any turn in the edge further focuses them within a distinct spot.Where do fish like to be in a river?
Look near islands or rock piles. On the downstream side of sandy islands or rock piles, you will find calmer water. Fish often rest, facing upstream, on the downstream side of a rock pile or island. These pockets of water may be large or small, but a smart cast in the right spot is likely to land you a fish.What is the best time to fish in a river?
