You can not control flood in the rainy season with Dam. Dam is meant to hold water in Dry season. In rainy season it is wide open. We already built enough embankment (No Dam) to control flood. So dont worry about flood.
Jiyo Einstein... Dams are made to store surplus water in Rainy season and releasing it in summer as well.. Dams are made to regulate water, generate electricity. By the time summer end, the dam water level go to minimum mark, In rain the dam get water, end of rainy season dams are almost full , or sometime over flow...
If there is heavy rain (very heavy rain) then god only can save.
Dams
Main article: dam
Many dams and their associated reservoirs are designed completely or partially to aid in flood protection and control. Many large dams have flood-control reservations in which the level of a reservoir must be kept below a certain elevation before the onset of the rainy/summer melt season so as to allow a certain amount of space in which floodwaters can fill. The term dry dam refers to a dam that serves purely for flood control without any conservation storage (e.g. Mount Morris Dam, Seven Oaks Dam).
[edit]
Most dams also provide flood control, and some are used to facilitate navigation. Dam reservoirs are essentially storage areas that can hold large amounts of rainwater and runoff when heavy rains hit. Dams have a series of gates, called spillways, that provide a tunnel or throughway for water from the full reservoir to be emptied into the river below, at a controlled rate. On a large river, like the Tennessee, the dams work in synch to keep each reservoir level stable, pouring water through the spillways, all the way downriver, as the elevation drops. In this fashion, no one reservoir bears the brunt of heavy rains.
