The extraordinary establishment of Grand Canyon National Park coincided with the astonishing rise of hydroelectric power generation, with the Colorado River Basin home to many promising damsites. The period from 1910-1930 was full of plans and schemes, and was crowned for the dam-builders by the 1930's construction and start-up of Hoover Dam, with its reservoir Lake Mead that extended some 40 miles into the Grand Canyon. 

The 1930's and 40's were full of more schemes and surveys, aimed at one or more damsites in the Canyon itself. These efforts were channelled in the late 1940's by the Bureau of Reclamation and Arizona into plans to use a dam at the Bridge Canyon site to generate electricity and bring water from the Colorado into central Arizona. The powerful sway held by the Reclamation view brought the National Park Service and non-governmental pro-Park organizations like the National Parks Association and the Sierra Club to a position of restive acquiescence. The Hualapai actively pursued its claim to a share of Bridge Canyon dam's benefits. When Congress insisted in the early 1950's that Arizona's water rights be adjudicated by the Supreme Court, Reclamation intensified its work on a dam in the Canyon's Marble Gorge and on a tunnel to divert the river around the National Park. 

In the 1950's and 60's, Arizona, as always alarmed by delay in securing its share of the Colorado's bounty, launched another effort to construct Grand Canyon dam(s) by itself, in alliance with the Hualapai. This effort was contested by Los Angeles, which had been scheming to control any such dam construction since the 1920's. In the same period, educated by dam fights in the upper Colorado River Basin, pro-Grand Canyon groups moved to a stance of opposing any dams in the Canyon. The Reclamation effort resumed in the mid-1960's, in an often-uneasy alliance with much of Arizona, parts of the federal government, and the other Colorado River Basin states. The Arizona go-it-alone faction was stopped cold in Congress. The Hualapai joined in support of a federal dam, re-christened Hualapai Dam. 
The climactic fight took place 1965-8, with a determined effort to authorize two dams. The effort failed; the dam dream of some had become too much of a nightmare for too many. Congress and the President instead took the path of declaring the Canyon off-limits to any more dams. In the 1970's, the Hualapai and the state Arizona Power Authority continued to promote the dam; gradually, even their effort flickered out.
