byproducts. There are two main typed of hydroelectric dams. One version uses the natural flow of the water to spin a turbine and generate electricity and is significantly less ecologically damaging than its counterpart, the gravity dam. A gravity dam spins a turbine by using gravitational energy to transport water from the top of the dam to the bottom and the massive push of water generates large amounts of electricity. These are the types of dams that are most familiar when considering hydroelectric

emptying into the Columbia River in Washington. Fifteen dams have been built on the 1040 mile Snake River and its tributaries, mainly for purposes of providing irrigation water and hydroelectric power, ranging in size from small diversion dams to major high dams. While the many dams have transformed the region's economy, they have also had an adverse environmental effect on wildlife, most notably on wild salmon migrations. Nearby Hells Canyon is one

water run throughout the United States; and since the country’s conception, over 80,000 dams have impounded 600,000 miles of these waters [1]. Dams were originally constructed to provide water to towns and establishes energy sources for mills and later hydroelectric plants. Because these dams were constructed decades ago, they’re reaching a critical point of obsoleteness where they cause more harm than good. Dam removal is increasingly popular across the country to address the ecological problems including

Beavers are known for two things, they long teeth and their dams. According to Beavers Solutions LLC “The dams, canals and lodges beaver builds have gained them the reputation as “Nature’s Engineers”. No other animal with the exception of man so significantly alters its habitat to suit its own needs and desires. Native Americans revered the beaver and referred to them as “Little People” for this reason.”. Beavers build dams or lodges to create pond for their food. Like the quotes says beavers transform

The St. Francis Dam was built in 1926 in the month of May by William Mulholland. Mulholland used concrete as the material to build the damn. The St. Francis Dam was Mulholland’s first concrete based dam. He had previous experience with earthen dams but decided to practice outside of his expertise and use concrete. This decision was was because the mountainous site lacked the sufficient amount of clay or water to construct hydraulic fills. The design of the downstream of the dam was a wide set of

didn't seem to study much about dams because the dam that he built was built on schist which water slides under. This man was known throughout History for his confidence of how to build the dam. He seemed pretty gruff and impatient, He seemed like he wanted to just get done with his work. Mulholland wanted to get it done because it was a very long task, There are some answers to why Mulholland built the dam badly. One reason is that it was probably too much on the dam. As the head of the department

usually think of the Grand Canyon in terms of its rocks, and the story and history that they can contain, spanning as far back as half of the Earth’s age. There is more to this canyon though than the rocks, as it is still active as a forever changing landform, due to the power of running water. The Colorado River has carved out the Grand Canyon in just the last nine million years. In fact, the river itself carries about half a million tons of sediment through the Grand Canyon each and every day. There

color of the river is more of a blue-green though, due to the creation of the Glen Canyon Dam in 1963. The silt and sediments that gave the river its reddish-brown color are now trapped behind the dam at the bottom of Lake Powell. Before the construction of the Glen Canyon Dam, the Colorado river could carry around 500,000 tons of silt and sediment per day through the Grand Canyon. The peak flow rate before the dam was normally around 85,000 cfs (abbreviation for "cubic feet per second" which is

The Hoover Dam is legendary. Having visited and stood on it’s bridge many times, there is no way to describe the incredible power that one feels just setting foot near the place. In 1922, the Reclamation Service presented a report calling for the development of a dam on the Colorado River for flood control and electric power generation. Even before Congress approved the Boulder Canyon Project, the Bureau of Reclamation was considering what kind of dam should be used. Officials eventually decided
