The pores are very small

Explanation:

Soil permeability is an important phenomenon that allows water and air to transmit from the pores of the clay. It is very important for the agriculture of fish etc. If a pond is constructed without permeability, soil loses the water through the seepage.

How much the soil is impermeable, as the seepage occurs according to it. Soil is made up of the layers. The quality of soil depends on layer to layer. It is very important that before construct pond first of all to determine the permeability and impermeability of the clay layers.
