Sanmenxia

The silt-laden, unnavigable Huang many times has broken through its dikes and changed its course, bringing famine with flood. In recent years the Chinese have tried to harness its power by building giant hydroelectric dams, notably at Sanmenhsia in Honan Province and at Liuchia Gorge near Lanchow. But work came to a standstill with the departure of Russian engineers in 1960.]
