How Did The Hoover Dam Affect The Three Gorges Dam

The one feature common to the Hoover Dam, The Mississippi river and the three gorges dam is that they all tried to control nature’s swings, specifically in the form of flooding. Before the Hoover dam was built, the Colorado river “used to flood spectacularly…but after 1900 the Colorado provoked a vehement response” (Pg 177). The response was simple, but large. The U.S. built several large dams, including the Hoover dam, on the Colorado to decrease its flooding and increase power and irrigation. Unfortunately, just as human control of the Colorado’s flooding increased, its organisms and habitats were detrimentally influenced, and the water became more and more salinated.

The Missisippi was also managed in New Orleans to limit flooding. This was done through levies that were at first naturally built by the river’s mud flows during floods. Later the levies were built higher and higher to keep the flooding Mississippi into the New Orleans area. But the levies were often ineffective in managing, or led to more flooding. Kelman explains this when they write “With the development in the Mississippi Valley ongoing and artificial banks confining more runoff inside the channel, the river set new high-water marks” (Pg 702). Yet this is not the only example of the failure of Mississippi river management. Only 10 years ago, New Orleans’ levies failed, an example of the inability to control the flooding.
