Water projects in the United States gained a new principle in the 1930’s.And during this time the nation suffered its worst economic depression and the Great Plains region suffered its worst drought in recorded history.(1) _______________________________________.President Franklin Rooseveh’s first 100 days in office brought a number of new laws to deal with the severe economic depression.The natural pattern of the Tennessee River was characterized by large spring flows that produced destructive floods and low summer flows that inhibited navigation.The intensity and frequency of the events discouraged development and contributed to persistent poverty in the valley.To counter these natural obstacles,the Tennessee Valley Authority Act of 1933 created the Tennessee Valley Authority (TVA),a public agency with broad powers to promote development in the region,including the authority to build dams and reservoirs and to generate and sell hydroelectric power.(2) _________________________________________.The TVA inherited the Wilson Dam,and by the beginning of the Second World War it had completed six additional multipurpose dams with power plants and locks for navigation.(3) ________________________________________________.The NIRA authorized the creation of the Public Works Administration to create jobs while undertaking work of benefit to the community.The NIRA also gave the United States President unprecedented powers to initiate public works,including water projects.
As the economy sunk into a deep depression and unemployment rates increased, the political climate for direct federal government involvement in water projects improved.
This organization used its authority to transform the river into one of the most highly regulated river in the world within about two decades.
Investments in dams and hydropower facilities within the Tennessee Valley also received high priority during the war.
