At the time of compilation, the movement of the Bail was about 1088 square kilometres. On the southern edge of the Chaklan Bail, Gomani river which flows the water of the Bail and goes to the big Bail and finally falls into the Jamuna. When the height of the water increased due to the flood of Jamuna, the Baral kept the Bails slightly and the water of the bail increased; The height of the water does not decrease till the Jamuna water goes down.

In the dry season, the larger part of the bail is dried and it becomes a water cistern of 25.9 to 31.08 square kilometres, which can be said to be the main part of the Bail. The main part of this is, however, deprived of continuous water supply, but some shallow water bodies, which are connected by every large zigzag canal.

It is obvious from the fact that there is a fast falling. The land is recovering and villages are being developed with Bail marks. Without the deepest part of the centre, all the small-and-large Bail of dry season are dried. Boro and high yielding paddy are cultivated during the dry season in the coastal areas outside the centre. During the rainy seasons, deep water Aman paddy was cultivated in shallow areas. In the northern part of the country, the fish needs to be filled with the bail of fish.
