Can Lake Mead be semi-saved?

With the kick-in of a federal Drought Contingency Plan earlier this year, Arizona, California and Nevada all have to cut the amount of lower Colorado River water they use. But, because of past deals Aridzona made with California so it wouldn't block progress on the Central Arizona Project, Aridzona will take the biggest hit, and California isn't really hit at all by Phase 1, as I discussed when the trigger hit.. That's even more true if Phase 2 of the DCP is triggered in just two years, which many people believe likely.

The Arizona Republic, via Yahoo, talks about a new voluntary plan hammered out among the three states that claims it will get deeper cuts than Phase 1 of the DCP mandates and so, hopefully, avoid Phase 2. 

Color me skeptical. We've already seen that  California water conservation seems to have hit a brick wall. While Pinal County, Aridzona farmers are drilling even deeper water wells, what if some of them start bringing up either sand or brine, and sooner rather than later? Or, some of this starts leaching from aquifers that are supposed to be part of the guaranteed 30-year water supply of new residential developments?

Per that second link, I expect negotiations to fail.

That said, what about DCP Phase 2, if it kicks in? Who's going to enforce the cutbacks? Them's fighting words.

That second link also indicates the lack of reality still in place.

Aridzona is talking about building desal plants in the Sea of Cortez and swapping that water with Mexico for a share of its Colorado River allotment. Desal plants, especially larger ones, have generally been a massive failure.

That ain't all. Lake Powell now reportedly has a 17 percent chance of hitting power pool in just three years. Power pool, per previous blogging, is when the lake falls below the level of the penstocks to generate hydroelectricity. That CAP water ain't going to Pinal County if there ain't juice to pump it there. And, considering that projection is by BuRec itself, the actual odds are surely higher.

Oops, that may be out of date. New BuRec report, per CNN, says 1-in-3, and by 2023. Same piece offers 66 percent chance of Mead hitting 1,025. That's DCP Stage 3. The first stage hit earlier this year at 1.075 feet; Stage 2 is at 1,050. At 1,000 feet, Vegas gets cut off. Also, at that point, Mead nears power pool.
