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This is in regarding additional problems with water use including groundwater depletion where water is withdrawn from the ground at a faster rate that it can be replenished.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.)

What are the green circles near the Goose Island Dam and how far upstream of the dam do they occur?

Explanation / Answer

Fresh water shortage and irrigation

We have to consider the national importance such as Agricultural growth and economic development.

We have to give the support to endangered species. So eliminate the construction of dams and choose alternative ways for water resources.

Due to dam construction the growth will increase

They are Agricultural fields and nearby the dam
