Study finds Colorado River Basin’s worst known megadrought was 1,800 years ago

Green Car Congress

The ongoing severe drought in the Colorado River Basin has led to the river flowing at 84% of its historic average flow. The new study used tree-ring data and other climate records to identify a drought period unmatched in severity by the current drought or other ancient droughts. Gangopadhyay, S., Woodhouse, C. McCabe, G. Routson, C.

Satellite study shows drought-stricken Colorado River Basin states depleting their groundwater

Green Car Congress

A new satellite study finds more than 75% of the water loss in the drought-stricken Colorado River Basin since late 2004 came from underground resources. The extent of groundwater loss may pose a greater threat to the water supply of the western United States than previously thought. This is a lot of water to lose.

Researchers use IPCC AR5 models to forecast 10% drop in Colorado River flow in next few decades

Green Car Congress

The Colorado River Basin encompasses much of the American West, covering parts of seven US states and two states in Mexico. It may not sound like a phenomenally large amount except the water and the river is already over-allocated. Population growth in the Southwest is putting added pressure on regional water resources.
