Just in case anyone thought that awareness of the likelihood of shortages on the lower river was a more recent phenomenon. Additionally, this is reported in a book that was written in the 1970s. 1945 was still a few years before the construction of Glen Canyon Dam, which certainly changed the projections for reservoir exhaustion at Mead, but the possibility remains frighteningly real.
