From The Pueblo Chieftain (Matt Hildner):
The basin’s projected water demand is expected to rise from 19,900 acre-feet in 2008 to between 28,450 and 34,000 by 2050…
The [draft state report on future statewide water needs] calculates that population would grow in the basin from 49,000 now to 88,000 in 2050, based on formulas used by the Colorado State Demography Office. The draft said the Rio Grande basin may see increased demand from industry for water in the future because of oil and gas and solar energy development, although it did not quantify the demand as it did for other industries in other parts of the state. Mike Gibson, the roundtable’s chairman, said the demands of solar power on the valley’s water supply would be minimal compared with agriculture. He cited a proposal from Tessera Solar, which is one of a number under review by Xcel Energy, that would consume 10 acre-feet per year to run a 200 megawatt concentrated solar plant near Moffat. He noted that a 120-acre field of potatoes would consume 164 acre-feet annually while a similarly sized field of alfalfa that sees two cuttings would consume 310 acre-feet in a year.
