The lakes created store water.
The Tampa Bay Hydro Dam is a way for the city to benefit from hydropower. This can greatly benefit the city and residents as it is a renewable resource.
a water way dam system to pass boats byound the dam
It efect the dam because on of the dams is moving a way and the other dam is going the other way and if the dam is built right were the river conects it would efect the river or stream.
replanting forests that have been cut down for lumber use
There are two main reasons for a dam's broad-base design, and both are explained by the fact that all materials have limited strengths. The only practical way to increase strength is by adding material. The first idea is that a dam has to support its own weight. The heavier a dam gets, the more material is needed at the base to support itself. Hence very large dams have enormous bases. The second idea is that the dam has to also support water behind it. The top of the dam is thinner because it does not have to support too much water; only the surface of the water needs support. But as the water gets deeper, the dam has to support all that water above , and then its own weight. At the bottom, the dam has to support all the water and its own weight. This means that as you get lower, the dam has to get stronger. And as mentioned above, the only practical way to do so is to add material.
A dam is a big wall to stop water getting through to certain places. It is also used to irrigate water, and some dams, to make hydroelectricity. Hydroelectricity is electricity that comes from water. It is a environment friendly way of getting energy or power. Dams are, of coarse, found mostly on rivers though always on water of some kind. Some are huge and some are smaller. For example, on the Euphrates River, the Ataturk dam, it very big and is used for quite a few things. It is found in Southeastern Turkey and is the 5th biggest dam in the world.
Actually, I think it's the other way around. That is, unless you consider precipitation of water from the sea to lakes.
Dams generally serve the primary purpose of retaining water, while other structures such as floodgates
A wier is a way to have a road cross a stream or wash. It also acts likes a dam, because it is raised a little above the water level, thereby limiting the flow of water past the point.

A dam is way to control floods by putting a large wall across a river
One way is by building a hydroelectric dam. This is where the water runs down a stream or river, into an area where the water rotates water turbines. Then, the water get sucked in or captured by a generator. The water is either stored for use later or converted into electricity right away. But the problem with this is that the dam can easily flood a large area which can badly harm the wildlife.
Density of water per unit volume ie. g/cm3 * depth of water (cm). Answer will be in g/sq cm. Density of water is approximately 1g / cm3 therefore pressure at the bottom of a dam wall with 1m of water = 0.1kg / sq cm. Note: this is only valid at the bottom of the wall, half way up the 1m of water the pressure would be 0.05kg / sq cm. At the very surface of the water, there would be no pressure. Thats why a finger in a dyke (dike) can hold back the North Sea!
