More on rivers today after yesterday's similar post.
During a discussion on the Middle Rio Grande Water Assembly discussion list on developing deep saline aquifers in New Mexico, Steve Harris of Rio Grande Restoration sent around this 1977 address by Albuquerque's favorite son, Luna B. Leopold.
Well worth reading.
"There are in various parts of the western states ground-water bodies too deep to be economically developed under usual economic standards, or they have marginal water quality. These, and especially those remnants of the ice-age ground-water bodies not being recharged now, should be saved from ordinary development and reserved only for times of exceptional need. But advance engineering is needed to explore and tap them and to connect to them transmission lines ready for some future contingency." ---Luna B. Leopold, "A Reverence for Rivers" (1977)
