3. water impoundment for public consumption, irrigation, recreation, etc.
Dams may prevent salmon from breeding by?
Dams can and have prevented the fish from getting to their normal breeding grounds which they have used for thousands of years.
Why is the three gorges dam needed for energy production?
It is a HEP (Hydro-Electric Power) dam, which means that it produces a vast amount of electrical power for China with minimal pollution. However its construction has had huge environmental and social impacts, many of which have been severely detrimental to China.
In a Car:
A tank to hold "overflow". When fluids heat up, they expand, and like radiator fluid, they need a place to go until they cool.
Some cars keep these under some pressure, and if there is a leak, then an engine light will now come on. In the older cars, a leak in this tank would be a minor problem because you'd loose fluid when it leaked out of the overflow.
The Anfat dam supplies potable water to Metro Manila and powers a hydro-electric power plant. The dam Angat dam was built in 1967 after a devastating typhoon.
How will the three gorge dam reduce flooding?
It will reduce flooding of the land beyond its position - by regulating the amount of water released downstream.
Dams were originally build so that farmers could have water to irrigate their crops, or to provide a source of water for a village or town. Beavers built dams so they would have a safe environment to live.
When electrical generators were developed dams were build to provide hydro-electricity as well, so most dams now have turbines to take advantage of the power of the water.
Shelter and their familes.
To stop water from flowing into cities and any populated areas.
AND CAUSE THEY WANT TO

What does a tour guide at the Hoover Dam earn?

Which produces more power-Bonneville or grand coulee dam?
Actual statistics are located at the bottom of this answer.
Bonneville dam's power production approaches 3x that of the Grande Coulee dam, although it's physical size is much smaller.
The reason for this is because, as with any other river, the farther down stream you go on the Columbia, the more tributaries (streams feeding larger streams or a lakes) there are that dump into it, each one increasing the rivers total water flow. This additional waterflow increases the power of the river, which in turn allow dams that are built lower on rivers to produce more power than those built farther upstream.

Which is the world's longest dam?
Grand Lake O' the Cherokees dam in Oklahoma
is only 1568 mt long, Hirakud Dam in Orissa, India is the longest in the world. It is 26 km or 16 miles long. The Afsluitdijk in the Netherlands, build between 1927 and 1932, is 30 km long (32.5 km if you take the parts on land into account). It divides the Zuiderzee (now called IJsselmeer) and the Waddenzee so it is really a dam not a dijk.
Which of the following is a benefit of using dams as a source of freshwater?
dams help control floodwater
What are advantages or disadvantages of building dams with the answers?
Advantages of dams:
- Dams are constructed based only on safety
- It is used to store water
- It used in hydroelectric power generation
- It is used in irrigation purposes.
- Fishing.
Disadvantages of dams:
- Requires skilled labour to construct
- Strong abutments is needed.
- Loss of habitat to many endangered species.
- Loss of shelter to many tribal people and they have to loose their occupation.
- Loss of hectares of forest land and shelter to many animals.
- Failure of dam leads to heavy loss.
- Heavy silt accumulation.
What is the 3 Gorges Dam and why is it important?
It is a dam in the Yangtze River in China. It is important as being the world's largest power station, as a means of limiting the flooding of the Yangtze, and as a means to increase the river's shipping capacity.
Can building reservoirs help in saving water?
Not necessarily. Building reservoirs simply provides the facility for storing rainwater. Its up to the actions of people - in recycling as much water as we can - that will ensure we have a plentiful supply !
