And its salinity level was.510 percent, water level was 52 metres, depth of water was 16 meters. The water level in the Aral sea started drastically decreasing from the 1960s onward. In normal conditions, the Aral sea gets approximately one fifth of its water supply through rainfall, while the rest is delivered to it by the Amu darya and Syr Darya rivers. Evaporation causes the water level to decrease by the same amount that flows into the sea, making it sustainable as long as inflow is equal to evaporation on average.

The Army was trying to get rid of its germ weapons and stored the bacteria on one of the Arals islands.

Soldiers dug large pits and poured a mixture of anthrax bacteria and bleach. The bleach was supposed to kill the bacteria, but it did not. Even with the passage of time, the bacteria stay alive. Now, the sea is drying out and this island can become a part of land. This fact carries the threat that anthrax bacteria can be exposed to atmosphere one day, and it will become a very serious danger to both countries. At this time, both governments in cooperation with the United States are undertaking actions in order to prevent the extension of the bacteria.

Another side effect imposed on the population is a dramatically increased rate of tuberculosis in the area. One of the causes of health deterioration is that over three decades the water could not or barely could make it to the Aral sea. The Arals water contains a lot of pesticides. The pesticides sank to the bottom of the lake. As the lake dried up, this layer of pesticide became exposed to the wind, which blows it away on the other lands.

The partial solution for the problem is to build a dam to keep water from flowing into the larger, southern portion. Plans call for the structures base to be 150 yards wide. If money is found for the construction, the water level of the northern sea will rise to the same level it was in 1960s. As a result of the construction, salination of the sea will decrease. This fact might contribute to restoration of fishing and resort industries. For the population of this region, the dam is a rare ray of hope.

In city of muynak, the three hundred-vessel fleet once employed a thousand fishermen. It is now a collection of rusting hulls half-buried amid the dunes on the edge of town.

The disappearance of the sea as a part of the ecosystem is just one problem that is followed by hundreds of subsequent problems.

One can see white ridges amid the soil in the field. Salty dust from the dried out land blows in squalls through the area, causing discomfort and respiratory problems. Wind brings more than a hundred tons of salty dust per square mile on the region every year. As a result of this, trees do not bear fruit any more.

disappearance of the sea, and the danger of the broad extension of anthrax bacteria that was stored by the soviet. In comparison with the size of the sea in the 1960s, the sea has declined in size by seventy-six percent. The initial reason for the Arals decline is the fact that soviet planners diverted water from Arals two big feeding rivers (Amu darya and Syr Darya) into cotton fields in the territory of Uzbekistan. Because of this irrigation, the sea is now seventy miles away from its former bank (in some places even more). Ninety percent of the syr dayas water is diverted into canals and reservoirs. Millions of people in Central Asia rely on the rivers for a livelihood. Uzbekistan, for instance, generates twenty-eight percent of its hard currency from cotton irrigated with river water (The Aral sea, planning the irrigation system, the soviet planners were only after high rates of cotton harvests. Unwise use of water has led to the current state of the Aral sea.
