The U.S. has more than 87,000 dams greater than six feet high (and two million overall). While many dams continue to provide benefits such as flood control, irrigation, and water supply, for other dams the cost of maintenance or the negative effects on communities, fish, and tribes justifies their removal.
Dam owners and regulators decide whether to remove a dam by weighing many factors including: the cost of removal and the ability to replace any lost power generation against avoided long-term maintenance; safety concerns; benefits to endangered fish populations; increased recreational and commercial fishing; and restoration of cultural values of nearby tribes.
By 2020, roughly 70% of dams will be more than 50 years old, inviting us to reconsider the value to the public of long-term investments in this infrastructure.

<h3>What do you mean by high altitude?</h3>
The distance above sea level is known as altitude, just like elevation. If an area extends at least 2,400 meters into the atmosphere, it is frequently referred to as being "high-altitude."
Mount Everest, which is located in the Himalayan mountain range on the border between Nepal and Tibet in China, is the highest point on Earth. 8,850 meters is how high Mount Everest is.
The highest city on Earth is El Alto, which is located in Bolivia. The average elevation of the 1.2 million population is 4,150 meters above sea level.
Air pressure decreases as altitude increases. In other words, low air pressure indicates a high apparent height.
Two things account for this. The primary cause is gravity. Density is the second justification.
