Not enough water to go around: the Colorado River Basin

This is a repost from the CBS News 60 minutes segment all about the Colorado River. The Colorado River has been hitting record low volume as seven states and 30 Native American tribes lying in the Colorado River Basin prepare to make hard choices as water levels plummet due to a 22-year drought. Bill Whitaker reports. Check out the full video segment below.

This is why it's so important to be involved in Colorado's Water Plan, as the Basin Implementation Plans are being updated and we need YOUR input right now thru Nov. 15. It’s time to make your voice heard: What do you think needs to happen in your local watershed for the health of your local rivers, the environment, and water supply?

TAKE ACTION

What's in a drought? That which we call a drought.

A report published by the Colorado River Research Group takes a look at the word "drought" and why it might be time to retire its usage based on the data seen from the Colorado River Basin.

“Drought: a period of dryness especially when prolonged; specifically : one that causes extensive damage to crops or prevents their successful growth”

— Merriam-Webster Dictionary

According to that definition, a drought refers to a period of time which would mean there is a beginning and a foreseeable end. What we are noticing in Colorado is a drought that seems to have no end. That's why scientists from Arizona, Utah, California, Colorado, and Michigan are starting to label the changes we have seen in the Colorado River Basin as aridification. It's true that the word does not share the same one-syllable punch that drought delivers, but the research groups says that it better defines what is happening to the area.

“aridification: the gradual change of a region from a wetter to a drier climate, often measured as the reduction of average soil moisture content”

— Merriam-Webster Dictionary

What this study suggests is that the years upon years of weather patterns we have seen in Colorado are pointing to a larger trend that is simply more than just a temporary drought or warming.

Other topics addressed in the report include: 

• Measuring the likelihood of future megadroughts in terms of low soil moisture
• What studies say about the "dust on snow" phenomenon
• What are two possible new normals based on climate models, trends, and Colorado population demand and growth
