Dam the Dams?!

Is It What We Think It Is?

Many people are stuck on the opinion that dams don’t harm the environment. There all wrong. If there’s one thing a dam does is destroy the life of the river. In this article I’m going to inform you all about the effects of a dam and how it is created.
The first thing you do when you when you want to build a dam is creating a diversion with a non-permanent dam called the cofferdam. The trick is to not take too long for the construction of the real dam or the river dries up and all life is starved downstream.
When the dam is finally built we start construction on heated gates and fish ladders. These are extremely important because first of all when water flows through a dam it is usually colder than it once was when there wasn’t a dam in the river.
This is why we use heated gates or else the life downstream can’t adapt to the change of temperature and freeze.
The reason we use fish ladders is for migratory (traveling fish like salmon. Some times when traveling upstream they bang into to dams and they can’t mate. In fact a very large percentage of salmon is cut every year because of dams.
Fish ladders are imitations of water drop-offs that fish usually jump over to get to their mating grounds. Dams also stop the flow of nutrients downstream which can starve the organisms in the river so we are very lucky to have solutions for these problems.

Dams can be used for flood control, power, deepening water for ships, irrigation and for clean drinking water. In fact some of the first dams were built before Christ .The hydroelectric dam works by letting water flow through a tunnel and then turns the turbine.
The water exits through gates at the front of the dam much cooler than when it entered the dam. Dams generate a lot of electricity and are very useful. Big dams like the Grand Coulee Dam make enough electricity to power entire cities!
I think this is important because dams create so much electricity and can be used to save the world from Global Warming…
