Using less and paying more. A conundrum it seems, until you dig a little deeper
Doing nothing about the Colorado River鈥檚 decline is too risky
Arizona is with its Colorado River water users about how to get by with less. There鈥檚 general acceptance that we need to use less Colorado River water now to prevent a crisis later. As details get worked out, there may be resistance because a drought contingency plan costs money鈥攜et doing nothing could cost a great deal more.
This almost 20-year drought is affecting water supplies across the Southwest. We already know the Colorado River System is over-extended 鈥 more water is taken out by water users than is put back in by snowpack and rainfall. Millions of people, businesses, birds, fish, and wildlife all rely on a healthy Colorado River and the water it provides.
Given today鈥檚 , in order to stabilize our water supply and reduce the chance that Lake Mead declines more rapidly, we鈥檒l need to incentivize those who would take their water to leave it behind Hoover Dam instead. Enter the Drought Contingency Plan (DCP).
The DCP, according to Bureau of Reclamation Commissioner Brenda Burman, is a seven-year agreement to 鈥渂uy down risk鈥 on the Colorado River system. She said it in the first word: BUY. In other words, .
A couple of reasons why DCP will cost money:
- Certain water users will need a financial incentive, aka payment, to leave their water in Lake Mead, instead of using it.
- Since some water users will be leaving more water in Lake Mead, less water will be coming down the 336-mile long (CAP) canal. When there is less water ordered, there is less water sold, yet the fixed costs to maintain this large piece of infrastructure remain. There are fewer units over which to spread costs. Therefore, cost per unit of water rises.
However, not implementing the DCP, not implementing a formal mechanism to encourage water users to leave more water in Lake Mead is far too risky, and potentially more costly, or catastrophic, to our economic and environmental livelihood. The cost of no DCP may be much greater than the cost of having a DCP.
DCP acts as an insurance policy to buy down risk. We buy down the risk of climate change and an over-allocated Colorado River system by using less water now. Our economies and our environment depend on it.
