Here’s a guest column running in The Denver Post, written by Allen Best, that gives an overview of the current state of the Colorado River. Click through and read the whole article. Here’s an excerpt:
Tow icebergs from Alaska? Pilfer from a tributary of the Yellowstone River in Wyoming? Or, even sneak water from the Snake, boring a 6-mile tunnel from a reservoir near Jackson Hole to the Green River? While it’s sure to make Idaho’s spud farmers cranky, it would help Tucson, Los Angeles and that parched paradigm of calculated risk, Las Vegas.
Interior Secretary Ken Salazar and everybody else with a megaphone has carefully branded these ideas as improbable or worse. Only slightly more credible is the idea of a pipeline from the Mississippi River. It could originate near Memphis, traverse 1,040 miles and, if reaching Castle Rock, rise 6,000 feet in elevation. Pumping would require a steady 800 megawatts of electricity, or a little more than what the Comanche 3 power plant in Pueblo produces.
In theory, this 600,000-acre feet of muddy Mississippi would replace diversions from the Colorado River headwaters between Grand Lake and Aspen. Those diversions range between 450,000 and 600,000 acre-feet annually. That would leave the creeks and rivers to the whims of gravity and geography, at least until arriving at Las Vegas and other places with growing thirst.
Cheap water? Not exactly: It would cost $2,400 per acre-foot for this Memphis-flavored sludge, assuming the idea isn’t grounded by protests from barge and riverboat operators. (Sometimes they, too, say they need more water.)
