Aral
The Aral sea has not been diverted, but much of the water from the rivers flowing to the Aral sea have been diverted for irrigation, particularly for cotton and rice production in central Asia.

The shrinking of the Aral Sea affected public health in the surrounding of the region because its enormous loss is the result of extensive irriagtion projects that have diverted water away from the rivers that feed the lake.
The main reason why the Aral Sea has shrunk so dramatically is because water from the rivers flowing to it has been diverted for irrigation. The Aral Sea basin is fed by the Syr Darya and Amu Darya Rivers, which flow directly into the sea. Other rivers feeding the basin are the Tedzhen and Murgabi Rivers and the Karakum canal, as well as shallow rivers from Kopet Dag and western Tien-Shan. Water from the two largest rivers has been diverted for purposes of irrigating Central Asia's rice and cotton production. Therefore, it could be said that human activity has been the main cause of the shrinking of the Aral Sea. The problem with the shrinkage of the sea is that desertification has increased. Salinity has increased, as have dust storms, and the desert which surrounds the Aral has recaimed more and more of the basin, meaning that the Aral's future looks very bleak.

The effect irrigation has on soil is that it dampens it, making it better for growing crops. To groundwater, irrigation fills it up with water. Rivers are affected by irrigation by the irrigation flowing into it.
It sounds like you're referring to irrigation, where water is diverted by ditches and canals to make land more suitable for planting crops. Irrigation ditches can divert water from free-flowing rivers and streams or from reservoirs created by dams.
Rivers, and the word is "dammed", not "damned".
I think the Inka tribe used irrigation.
