Question

This is in regarding additional problems with water use including groundwater depletion where water is withdrawn from the ground at a faster rate that it can be replenished. Many areas of the Mid-West are experiencing this. In many locations, dams are used to divert water to areas that need it. For example, Hoover Dam provides electricity for Las Vegas and also water to cities in the southwest as well. But, dams also have very significant environmental impacts. Four dams along the Snake River in Washington State were built to generate electrical power and provide irrigation water to farmers. The Snake River produced half of the chinook salmon in the Columbia watershed before these dams were built. By blocking migration routes, the dams threatened this species. The Snake River sockeye was the first of 13 salmon and steelhead stocks in this watershed to be declared endangered. The federal government was forced to prepare recovery plans, but over the past 15 years, the courts have repeatedly rejected proposed plans that tried to protect the salmon while still maintaining the dams. Should we maintain the dams, or should they be eliminated to protect the salmon? What do you think? How should we weigh the economic, ecological, cultural, and health effects of projects such as this?

This is regarding Freshwater Shortages. Open Google Earth and in the search box enter: Ice Harbor Dam. Click Search. Zoom out to see the darker (previous size of the lake) and lighter green areas (present size). Zoom out a little to see Goose Island itself just to the west (left). Zoom in on the Snake River and travel east until you reach another dam. Be sure that “Roads” is checked in the left column. When you find a dam zoom WAY in to see the name of the road either over or leading to the dam. This tells you the dam's name. Continue upstream, toward the east to locate the other two dams. Don't get tricked by railroad and bridge crossings.)

Besides Ice Harbor Dam, what are the other three dams on the Snake between the Columbia and Lewistown?

Explanation / Answer

In this question the application of dam were well explained how it is helpful for the economic development of any country by different means like generating electricity irrigation and hazard controls.

During dam construction we should keep in mind several parameters which are very important like catchment area surrounding locality geological structure geomorphic drainage patterns and affect on biodiversity. According to my opinion development of country is more important for different aspect in which dam construction/maintenance also playing very important role although protecting species is also government duty. BUT keeping some parameters is very important before to put any decision like most of the species are diverted them according to habitat and time frame is one of them.

AS we know very well how a single dam can effect on development rate of large number of peoples and area and finally country. So it’s very important to make proper maintenance of DAM. On rating basis we should weigh first the Economical on project health.

Total fifteen dams have been constructed along the Snake River. Besides Ice Harbor Dam, the other three dams on the Snake River between the Columbia and Lewistown are-

1)      Lower Monumental Dam

2)      Little Goose Dam

3)      Log Cabin Island (Lower Granite) Dam
