just a few before I go to bed
First off on my 3% of this planets water is considered fresh drinkable water. Of that there percent 68% is in glaciers.
Water in ground often know as aquifers fill at a certain rate. the available water in a given location will decrease as use raises above the refill amount. Also water can.be contaminated by a variety of human activities .
Dams effect the flow of water, shape of the land and impact on wild life. If a Dam is built in one location, locations below it will receive less water.
Only 3% of the planet's water is fresh? Have you ever been to the Mississippi River? How about the Sacramento and San Joaquin Rivers? They NEVER stop flowing, even in drought years so, that means, communities that depend on them for fresh water have a constant supply of it.
Also, Sacramento has another river called the American River that NEVER stops flowing. It doesn't flow as much as the Sacramento River though. So, Sacramento has TWO rivers that always provide it with fresh water and this winter has been one of the wettest on record and the Sacramento Water managers voted to continue drought water restrictions because they said that people have to get used to using less water.
The dams in California are so full they are releasing water through their spillways. The water behind the Oroville Dam actually overflowed the side dam emergency spillway, yet, Californian's are told they have to not use as much.
The ground reservoirs have been pumped out too much by the California farmers but that is because California won't let them use river water to irrigate their farms. The reason is because the extreme environmentalists have convinced the government that taking water from the rivers reduces the fish populations. Once again, the major rivers in California NEVER stop flowing, even in drought years.
Dams affect water flow, shape of the land, and impact wild life? Yes, dams affect water flow, they reduce the highs and increase the lows.
Dams affect the shape of the land, so, you don't like the way they look, that's it?
Dams affect wild life? They do, they're reservoirs provide a large marine habitat and a source of water for game. Did you think the lake created by a dam was empty of life?
Locations below a dam receive less water? Only in winter, in summer they receive MORE water. That's what dams do, they fill up in winter and release that water in summer, so, the rivers below them have a more regular flow.
