During the day, look for a steep river bank with huge stones, a stump pier, a tree and water area or a ridge with a water depth of 1.5-2.5 meters. (2) During the period from 5 pm to before dark, carp have the habit of cruising and eating. At this time, it is more appropriate to find a corner with overgrown grass and narrow river surface in the coastal area of 1.5-2.5 meters. (3) In case of rising water, as long as the current is not very urgent and muddy, it is a good time to catch carp. But the choice of fishing position is different from peacetime. It is mainly to find the entrance and exit of the river from the overflow, the pool, the backwater entrance of the upper weir and the lower weir, which should be near rather than far. Generally, the water depth of 2~3 meters is a safe harbor for them to avoid rapids.
