What was one environment consequence of the Hoover Dam  being built?

Whenever a dam is built, it creates a lake, in this case Lake Meade. The lake then grows and smothers the plants in the surrounding area. These plants then die off and because they decay in an anaerobic environment, they give off methane, which is a greenhouse gas 10 times as potent as carbon dioxide. Hope this helps :)

An objective analysis of the effect of constructing a sea-level canal across Central America is attempted. This canal, unlike the present Panama canal, has not been built, though it is a feasible proposition. The canal would run almost north-south, and would be 50 miles long. Proposed routes are noted; these resulted from a joint study by the US Army Corps of Engineers, the Atomic Energy Commission and the Panama Canal Co. in 1964. Extracts from their report are reproduced. In evaluating the report, the author takes account of some biological and physical features of the area, with particular attention to the potential effects of allowing mixing of Atlantic and Pacific biotas. The work of the Committee of Ecological Research for the Interoceanic Canal (CERIC), established to investigate the possible effects of building the canal, is reviewed. Finally, an alternative plan, involving the construction of a third, larger, set of locks on the present canal is presented, and the author concludes with the hope that ecological impact of canal building will be given as much attention as economic etc. when the decision to build, or not to build, the new canal is taken.

Dams and levees change the course of rivers.  Farmig, forestry, and suburban development lead to erosion.  Mining can change the forms of mountains.

The most power plants burn coal to generate high pressure steam, which is then passed through a turbine to generate steam.  The leftover steam, now cooler and at a lower pressure, is collected, cooled, and then recycled to the boiler to begin the process anew.\n\nThe most obvious environmental impacts are from combustion - this releases pollutants such as carbon dioxide (a greenhouse gas), nitrogen dioxide (which contributes to ozone, or smog, formation), and carbon monoxide.  Depending on the fuel used, impurities such as sulfur or mercury may also be emitted.\n\nOther ancillary environmental impacts include waste residue from combustion - for example, disposing of the ash from coal requires a landfill.  Also, a great deal of water is used for cooling purposes in most power plants.  If the water is drawn from a nearby river or lake, it will likely be discharged back to that water body, but often at a higher temperature.  This can negatively impact ecosystems.  Finally, the process by which the fuel is obtained can have significant environmental impacts of its own - consider the mining necessary to obtain coal.

Obviously, don't get that stuff on yourself.  There is also the waste material produced (but all energy production involves waste which is the inefficient use of material in the production of energy).  Finally, remember that no one died at Three Mile Island.

There is no particular change in the regulations.  What likely happened, is the particular power plant negotiated with other plants that were more efficient in controlling polution and "bought" some of their credits so they could use these to pollute at a higher level until they get their act together too.

Yes, after constructing the dam, they do cause an area to be "flooded" but it is usually a very low-lying wet place anyways. The sad thing is that sometimes they take some historic sites, cemetaries, & even some people's homes. See website below about how Santee Lakes were created in SC. One of SC's Revolutionary War hero's homes *was covered for that purpose.\n\nSediment will keep building up behind a dam. I am not sure if this compromises the structure of the dam; I guess that depends on materials from which the dam was constructed.\n\nThese sediments will start filling in the lake.\n\nFish that go upstream to spawn will have a barrier so it may cut fish populations upstream.\n\nI can't think of anymore.\n\nDownstream is more detrimentally affected than the upstream.\n\nThere is less water being channeled through the stream/river bed. This can be a problem for cities that use the river as a water source or for irrigation.\n\nExample: Colorado River in western US has several dams of which the most notorious are the Glen River & Hoover Dam. I think there are about 6 or 7 along the entire stretch of the river. B/c of this, all the water in the river is completely depleted before it ever reaches the Gulf of California; it actually dries up before it gets there!\n\nKeep in mind, you are in an arid region which requires irrigation. But the whole point of me telling this is that dams are used to reservoir the water & that is where they mostly get their stores/supplies of water.\n\nAnyway, as with anything else, dams serve for good as well as they do for bad. It's just a matter of weighing the whole thing out.\n\n:)

interaction of man with the environment is definitely essential for his survival.but the important thing is  not to exploit it.man should somewhere become satisfied and draw the line.man's insatiable quest for everything is leading to the exploitation of the environment and ultimately environmental pollution.

They are planning some new dams in some very exotic locations in South America.  The climate of equatorial regions may have some interesting affects on dam materials.

During the 1960's, Shell Chemical Co dug a well (12,500 ft deep) to dispose of toxic waste water at the Rocky Mountain Arsenal at Denver, CO. The volume of waste water injected into the well  lubricated the layers of subterranean rock enough that it created small earthquakes. Some registering 3.5, and several hundred in number.
