The Water Knife
https://www.usbr.gov/projects/index.php?id=504 |
Almost 97% of the world’s water is salty or undrinkable and 2%
is locked in glaciers and ice caps. That means that all living things on the
Earth rely on just 1% of the world’s total
water supply.
The book The Water Knife paints a vibrant picture of what
life may look like in the near future if our climate problems aren’t addressed
soon. The author Paolo Bacigalupi hones in on life in the Western states of the
U.S.-- namely Arizona, and to a lesser extent, Nevada and California. He describes a world where water is entirely
too scarce to support life in the regions that were originally desert. The author
makes many mentions of the Central Arizona Water Project (CAP) and its fictitious
destruction in his novel. Turns out the CAP is real, and I decided I wanted to learn
more about it.
Firstly, in the early 1900s, seven states who share the Colorado
River Basin settled on how they were going to share the water. They ended up
dividing the river basin into Upper and Lower Basin with each basin given 7.5
million acre-feet (MAF) of water. Arizona was allotted 2.8 MAF of the Lower Basin’s
water supply. 1 acre-foot of water provides a year’s worth of water for a
family of five.
In 1968 current president Lyndon B. Johnson signed the
Colorado River Basin Project Act, which permitted the construction of CAP by
the US Department of the Interior’s Bureau pf Reclamation. Its purpose: to
provide a means of moving 1.5 million acre-feet of Arizona’s water from the
Lower Colorado River Basin to the most populated areas of the state. It was
also created in the hopes of limiting how much groundwater was used for
farming.

The CAP is a system on canals that extend over 336 miles and
raises the water over 2,900 feet in elevation over the course of the system.
The system also includes 14 pumping plants, 39 radial gates, more than 50
turnouts that deliver water, and one hydroelectric generator. It is so large
that, depending on water flow, water can take up to a week to ravel from
beginning to end. This massive project
allowed one of the country’s driest states to also become one of its fastest
growing with a current population of over 6 million people.
Paolo Bacigalupi predicts a dark future for the CAP and the
western states. Knowing how important the CAP is to Arizona, I can see exactly how
devastating its destruction would be.
Wow that is crazy, its scary to think that if CAP was to fail how lost Arizona would be and how true the book would be. I had no clue how much the CAP actually did that is amazing. It also shines light into how powerful CAP truly is and how without it the driest states would be like the book showed them to be.
ReplyDeleteI didn't know what CAP was before we began reading the Water Knife. A lot of us didn't. It's amazing to know how much it does, but it's also scary to think about what happens if it fails. Great blog post!
ReplyDeleteThanks for the information on what CAP is. It's incredible to me how much mankind can do if we put our minds to things. Too bad we don't put our minds to many things anymore. Crazy to know that we are living off of 1% of our natural water supply...
ReplyDeleteIt is clearly a massive construction; the question is will it work in a climate change world of drought and increasing water scarcity?
