Digging the main drain

10. The main drain starts at one dam and ends at another dam.

It is dug with a hoe and a shovel, right through the middle of the field. Dig it as straight as possible: if it is not straight, the water is slowed up and can destroy the levees.

Levees are little walls on both sides of the drain. These walls are made with the earth dug out when digging the drain. The main drain carries away the water after it has irrigated the rice field.
