Vozrozhdeniya Island Vozrozhdeniya Island Vozrozhdeniya Island () was an island in the Aral Sea. The former island's territory is split between Uzbekistan and Kazakhstan. In 1954, the Soviet Union constructed a biological weapons test site called Aralsk-7 there and on the neighboring Komsomolskiy Island. Vozrozhdeniya was once a small island; it was only in the nineteenth century. However, in the 1960s, the island began to grow in size as the Aral Sea began drying up as the Soviet Union dammed its feeder rivers for agricultural projects. The shrinkage of the Aral continued and accelerated over time. Vozrozhdeniya became a peninsula in mid-2001
Rivers of New Zealand scenic rivers. Over half of the electricity generated in New Zealand is hydroelectric power. Hydroelectric power stations have been constructed on many rivers which dam the river completely, or channel a portion of the water through the power station. There is large hydroelectric power scheme in the North Island and in the South Island where water is diverted between rivers using a system of canals that is used to maximise the electricity generation. River conservation is threatened by pollution inflows from point and non-point sources. In the past rivers had been used for pollution discharges from factories and municipal sewerage
