Use

Tabalong River provides a large swamp land, which can be used to grow rice during the dry season. However, in wet season, the discharge of the river and its tributaries increases so high, that it often threatened the harvest and caused flooding in the nearby villages.[7][8] Therefore, the local government builds flood gates to control the flow and prevent floods.[9]

The abundance of water during the wet season is actually useful to fill up the pools for fishery.[10]
