Ahh, 1933. Native American children chasing chickens, the sweet smell of wheat on the air, and- a giant dam? The Grand Coulee dam left an enormous impact. Whether it was a negative or a positive impact, we're going to find out.
While dams are a great way to decrease the use of fossil fuels, construction leaves a massive negative impact. For example, the Grand Coulee Dam made salmon unable to migrate downriver to lay their eggs, thus forcing salmon to overpopulate or die out in that area. Another negative impact on the environment was getting materials to build the dam. I mean, those 12 million cubic yards of concrete had to come from somewhere.
Another notable impact was the death count. Seventy-seven workers died while building the Grand Coulee Dam, and it took eight years to construct it. Even though the 1930s were called the Great Depression, I'm sure these people still had a lot to live for, and these families must have been sorry to see them go.
While there were many negative impacts, the dam still helped society in many ways. For example, it still provides more than twenty-one billion kilowatts of electricity each year, and the energy is clean. Meaning, it doesn't pollute the air or the water.
The environment was also affected healthily. All that extra water helps trees and undergrowth, along with fish and land animals. Crops were also healthier and the economy grew. The dam also provided the power needed to make aluminum, which helped during World War II.
