. Some 2,000 villagers were resettled to make way for the dam's reservoir. Many claim they did not receive adequate compensation for the loss of their livelihood and only received compensation for 80% of their land. Furthermore, they claim that the land in the resettlement village is of poor quality and few crops can be grown, and that a proposed irrigation canal was never built.

. More than 144,000 floating solar panels were installed in 2021, increasing the power to 45 MW. Though covering less than 1% of the reservoir's surface area, the floating solar panels prevent 460,000 cubic meters of evaporative water loss per year. There is a park near the dam headquarters and a restaurant and bungalows for visitors. There is a golf course in this area also, at the north end of the lake. The ''Nature Walkway'' was introduced in 2021. This viewpoint offers tourists a good overview of the reservoir.
