How did the New Deal reshape western communities and politics?Also, what specific programs had the greatest impact in the region? How are these changes still visible today?
The New Deal reshaped the West largely through creating new infrastructure that allowed much of the West to grow.
To me, the program that had the biggest impact in the region was the construction of the Grand Coulee Dam. The dam did two major things -- it allowed for the irrigation of much of Central Washington state and it created a large supply of cheap electricity that powered such industries as the aluminum industry during WWII.
The change is still visible today from my window as I type this. I live in the middle of the Columbia Basin project in Central Washington. Without the dam, my area would not be able to produce all the agricultural products that it now produces. And we would not have the cheap electricity that brings quite a bit of industry to our area.
