A local company Ekapa Mining, moved 26,000 tons of material to create the island. All was delivered along a narrow 200m causeway, and deposited in an S-shape to create two bays. The dam typically supports 20,000 lesser flamingos, but occasionally over 50,000 lesser flamingos are present, a large proportion of the subregion's total population.
The dam has high concentrations of blue/green algae and diatoms providing the main food source for the flamingos whilst ponds provide clay for the flamingos to collect and build their nest turrets.
