{'answer_start': array([-1]), 'answer_text': array([''], dtype=object)}
The dam discharges its reservoir during the dry season between December and March every year.[99] This increases the flow rate of the river downstream, and provides fresh water for agricultural and industrial usage. It also improves shipping conditions. The water level upstream drops from 175 to 145m (574 to 476ft),[100] preparing for the rainy season. The water also powers the Gezhouba Dam downstream.
