Evaporation

December 28, 2015--University of Colorado scientists say reservoir evaporation a concern (Durango Herald)

 A focus should be placed on measuring and reducing reservoir evaporation in an effort to meet Colorado’s growing water supply demands, according to a study by the University of Colorado Boulder. The report, unveiled on Monday, focused on conservation, a popular theme touted by water managers across Colorado.


Report: Colorado River Water Evaporation Increases Due to Climate Change

A new report from the U.S. Bureau of Reclamation predicted an 8 percent increase in irrigation demand on the lower half of the Colorado River Basin and a 10 percent increase in evaporation from Lake Mead by 2080. The upper half of the Basin, above Glen Canyon Dam in Arizona, is expected to see demand for agricultural water jump by almost 23 percent, while Lake Powell loses 7 percent more water to evaporation than it did during the last half of the 20th century. The estimates are based on a projected temperature increase of about 5 degrees across the region.

The Colorado River faces a dual threat from climate change as rising temperatures increase the demand for irrigation water and accelerate evaporation at the river’s two largest reservoirs. So says a new report from the U.S.


January 24, 2015--Scientists measure reservoir evaporation to gauge water scarcity (Water Online)

Scientists are trying out a new approach to drought and water scarcity monitoring: They are measuring how much water evaporates from reservoirs in order to provide a more accurate picture of how much water is available.

Water stress — the general scarcity of freshwater for people who need it — is considered by many scientists as one of the biggest challenges facing humanity and struggling ecosystems in a world increasingly affected by climate change. Studies differ on how much the world’s growing population will be affected by the growing diff

[Opinion: Michael Black] I have been reading with amusement the trials and tribulations of Ridges Basin Reservoir. The old joke at Taxpayers for the Animas River was that if the Ute tribal members ever wanted to use the water in the reservoir, they would need to buy speedboats. Now, it appears even that won’t do.

John Martin Reservoir was created in 1948 for flood control and to divide the water of the Arkansas River between Kansas and Colorado. Congress approved the Arkansas River Compact in 1949, after the two states signed it in 1948. It is operated by the U.S. Army Corps of Engineers.

A collaboration of scientists from the US Department of Agriculture and the University of California Davis, among others, has introduced a precision instrument that can determine the water loss, or surface renewal, of agricultural systems that are threatened by water scarcity and climate change.


July 11, 2013--Climate change's heat intensifies drought in the USA (USA Today)

While drought has several causes, climate scientists say global warming is a long-term contributor that could be exacerbating current conditions, especially in the already-arid Southwest. They say it will likely do more damage in the future. Why? Higher temperatures cause more water to evaporate, and unless there's enough rain to offset it, the ground dries up. More heat is on the way, too.
