The general consensus among inhabitants of the Colorado River basin and government officials was that a high dam had to be built on the Colorado to control floods and provide carry-over water storage for times of drought. Possible locations for this dam were debated for years, and in fact the Bureau of Reclamation's first study for a dam at Glen Canyon was made in 1924, in addition to studies for locations at Black and Boulder Canyons lower on the Colorado, below Grand Canyon. These studies found that the lower Colorado sites had stronger foundation rock which might result in less reservoir seepage. The Glen Canyon site, furthermore, was so remote that delivering supplies and transporting workers there would be infeasible at the time. However, what really killed the first Glen Canyon proposal was the fact that it lies upstream of the Lee's Ferry dividing line, and thus would be considered the Upper Basin's water. With its substantial Congressional clout, California refused to allow the "virtual faucets" of a Colorado River dam "to be built in what amounted to hostile territory."
