In a river, the downstream suddenly widens, or there is a depression, which is counted as the slow flow of water in the bay. Small fish will rest in the bay and attract carnivorous fish to eat.

2. Bridge bottom

The shade under the bridge is very low, especially in summer. People are afraid of heat, so are fish. Naturally, they will find a shady place, and there will be uncleaned gravel at the bottom of the bridge when it is built. The ambush fish will hide and ambush the passing small fish.

3. Dam sluice

There will be food washed down from the upstream at the water outlet, and there is plenty of oxygen, so a large number of small fish will gather. If there are many small fish, carnivorous fish will come to hunt. Moreover, the sound of the current is loud, which will make carnivorous fish relax their vigilance and be easier to catch.

Slow down the rapids.

When there are ridges and dam exits in the river, rapids will form, but if the river widens or there are big stones blocking the water flow on both sides of the rapids, slow-flow areas will be formed, and the ambush fish will hide here and wait for the tired little fish at the top.

5. Deep knot

When you see that the color of water is very obvious from shallow to deep (which can also be seen through satellite maps), it shows that there is a height difference in this area. Small fish like to eat in shallow water, and ambush fish will hide in deep water and wait for opportunities.

6. Rock areas

Because there are many large and small pebbles and branches in the rock area, it is the only place for ambush fish. Fishing with soft worms will increase the chance of winning and reduce the chance of hanging the bottom.
