The principle--on a grander scale--is the same as that of the Tennessee Valley Authority of the 1930s, and the 1950s St. Lawrence Seaway, both shown on the map. NAWAPA could supply an additional 135 billion gallons of fresh water to the United States, Canada, and Mexico, plus power, and vast new areas of cultivation. It would involve thousands of skilled jobs to construct and operate.
When you visualize overlays on this NAWAPA map, of expanded rail links, magnetically levitated routes, upgraded levees, and new power, water, and mass transit for cities, plus refurbished farm regions, you begin to see the vast overdue projects and potential at home in North America.
