The takeaway from the “500-plus plan,” the recently inked effort to save Lake Mead, can be summed up in just three words:
We’re. Not. Done.
That doesn’t make the deal any less consequential.
A federal plan to spend $210 million on water conservation programs includes $40 million for “conserving 500,000+ acre-feet of water over the next two years to stabilize the decline of Lake Mead.”
The plan also includes $10 million for efforts to suppress wildfires in the West.
Trying to stave off dangerously low levels of water in Lake Mead, officials in California, Arizona and Nevada have reached an agreement to significantly reduce the amount they take from the Colorado River.
The problem took on new urgency this summer when the federal government declared a first-ever water shortage in the 86-year-old reservoir near Las Vegas.
State water agencies in Arizona, California and Nevada announced a $200 million investment in Colorado River conservation projects on Wednesday, in a last-ditch effort to keep the basin’s biggest reservoir from dwindling to dangerously low levels.
The cross-border collaboration, which also includes the Department of the Interior, will aim to add 500,000 acre-feet of additional water to Lake Mead — the Colorado River’s largest reservoir — in 2022 and 2023, by facilitating initiatives that promote water conservation in the Lower Colorado River Basin, according to the partners.
That additional water, which is enough to provide for 1.5 million households each year, would boost the reservoir’s level by 16 feet, a news release from the agencies said.
The river that supplies water to about 40 million people is getting worryingly dry. Since the federal government officially declared a water shortage this summer, the Colorado River has been thrust into national headlines, and so have the scientists and decision makers who track and shape its future.
The Central Arizona Project’s governing board took the first steps Thursday toward approving Arizona’s share of a plan to save a half-million acre-feet a year of Colorado River water in order to prop up ailing Lake Mead.
The plan, adopted unanimously by the board, calls for Arizona users of the river water — mostly those on CAP supplies — to shoulder more than 40% of that total, or 223,000 acre-feet in 2022. The cuts are all supposed to be voluntary and temporary, and to be compensated by either state or federal money, totalling $100 million a year for the entire conservation program.
Arizona’s water authorities are close to entering into a new pact with officials from Nevada and California they hope will restore water levels at Lake Mead and stave off future rationing requirements.
A Tier 1 Colorado River water shortage begins in 2022, triggering a mandatory 512,000 acre-foot reduction to Arizona. The emergency stems from the Lake Mead reservoir reaching water levels not seen since its construction. The designation doesn’t affect Arizona residents, rather the state’s agriculture industry that represents the majority of water usage.
Two and a half years after signing a deal aimed at averting a damaging crisis along the Colorado River, water officials from California, Arizona and Nevada are discussing plans to take even less water from the shrinking river and leave it in Lake Mead in an effort to prevent the reservoir from falling to dangerously low levels.
Representatives of water agencies from the three states said they are firming up the details of a deal that would leave an additional 500,000 acre-feet of water in the reservoir next year, and the same amount again in 2023 — about double the quantity of water used annually by Las Vegas and the rest of southern Nevada.
When a fierce early-season storm drenched parts of Northern California last month, some experts said it was in the nick of time.
Reservoir levels were critically low. Soils were parched. Fires rampaged through dry forests.
There was general consensus among climate experts that not even the record-breaking downpour would end the two-year drought plaguing the state. There was too much of a deficit, and a single storm — even of biblical proportions — would not be able to solve it in one fell swoop.
Arizona, California and Nevada are moving forward with a plan to save another 500,000 acre-feet of water in Lake Mead annually until 2026.
We’re talking 500,000 acre-feet over and above the mandatory cuts that are spelled out in the 2019 Drought Contingency Plan (DCP). Each year. For five years. Just to keep the lake from tanking. That’s a significant amount of water. That required a significant bit of negotiation.
The so-called “500-plus plan” is the result of a provision within DCP that required the Lower Basin states to “consult and determine what additional measures will be taken” to keep the lake from falling to a dangerously low elevation of 1,020 feet.
