The nation’s two largest reservoirs, Lake Mead on the Arizona/Nevada border and Lake Powell on the Arizona/Utah border, were brim full in the year 2000. Four short years later, they had lost enough water to supply California its legally apportioned share of Colorado River water for more than five years. Now, 17 years later, they still have not recovered.
Colorado faces an estimated water deficit of 560,000 acre-feet by 2050, due in part to an expected population increase. But it has a long-term plan to address that looming shortage. … To learn more about the [Colorado Water] plan, Water Deeply recently spoke with Bart Miller, Healthy Rivers Program director at Western Resource Advocates in Boulder.
There was no electricity when Vickie Buchanan’s family came to Diamond Valley in 1958. Nor were there many crops. But there was water, and as early settlers, Vickie’s parents were given priority access under a rule fundamental to Western water law: “first in time, first in right.” A steady flow of farmers followed, planting alfalfa and timothy hay grass in the high-desert soil of the central Nevada valley.
A federal forecast of water levels at troubled Lake Mead took a big turn for the worse this week — a 20-foot drop in the lake’s expected January 2019 elevation. The U.S. Bureau of Reclamation’s monthly prediction for Colorado River reservoir levels says the lake could drop to 1,076.53 feet by the end of 2018 or Jan. 1, 2019.
The effects of lingering drought, and the unrelenting demand for water from farmers, cities, and energy producers converged today at Lake Mead, which drained to its lowest level since 1937 when the Hoover Dam closed off the Colorado River to begin filling the largest reservoir in the United States.
Lake Mead, the reservoir created by Hoover Dam, is anticipated this week to reach its lowest water level since the lake’s initial filling in the 1930s. The Bureau of Reclamation’s Boulder Canyon Operations Office is projecting the elevation to drop to 1,081.75 feet above sea level during the week of July 7 and to continue to drop, reaching approximately 1,080 feet in November of this year.
Drought in the southwestern U.S. will deplete the vast Lake Mead this week to levels not seen since Hoover Dam was completed and the reservoir on the Colorado River was filled in the 1930s, federal water managers said Tuesday.
Lake Mead — America’s largest reservoir, Las Vegas’ main water source, and an important indicator for water supplies in the Southwest — will fall this week to its lowest level since 1937 when the manmade lake was first being filled, according to forecasts from the federal Bureau of Reclamation.
From the Las Vegas Review-Journal Outdoors, in a post by C. Douglas Nielsen:
If you have not yet done so, and should you have the chance, get a firsthand look at the Colorado River between Hoover Dam and Willow Beach. While it is impressive to look down upon the river from atop the dam, experiencing the river at surface level is even more remarkable.
Scientists say it would have been a catastrophe of unprecedented proportions. If the Glen Canyon Dam had failed, it would have changed the lives of millions of people and reshaped the history of the American West.
Arizona could be forced to cut water deliveries to its two largest cities unless states that tap the dwindling Colorado River find ways to reduce water consumption and deal with a crippling drought, officials of the state’s canal network said Tuesday.
“A point-counterpoint debate about whether one size fits all and the federal role in managing regional water resources took added significance Thursday during an American Bar Association water-law conference at a casino in drought-threatened Las Vegas.”
“The Colorado River basin is being listed as a critical conservation area under a new multi-billion dollar program that will fund conservation and soil-protection efforts, U.S. Secretary of Agriculture, Tom Vilsack announced Tuesday.”
From the Las Vegas Review-Journal, in a commentary by David Festa and John Entsminger:
“Today, there is water flowing in the Colorado River Delta — where water has not flowed regularly for half a century — all because water managers, conservation organizations and policymakers in both the United States and Mexico were able to find common ground. …Someone cue music heralding the ‘new era of Western water management.’”
From the California Department of Water Resources (DWR):
“Thousand-year tree-ring reconstructions of river flows prepared by the University of Arizona for DWR are highlighted this week at a Scripps workshop in San Diego. The workshop, led by DWR Deputy Drought Manager Jeanine Jones, is to examine patterns of climate variability that may provide predictive capability for drought or help support climate change modeling.
“A federal appeals court says environmental reviews were properly done on the nation’s largest farm-to-city water transfer, the latest ruling to uphold a 2003 agreement on how California agencies divide that state’s share of Colorado River water.”
“The Colorado River has been reunited with an old friend—the sea. Thanks to an agreement between the U.S. and Mexico, water from the river has reached the Sea of Cortez in northwestern Mexico for the first time since either 1998 (according to National Geographic) or 1993 (according to AP).”
From the Environmental Defense Fund (EDF) Voices blog, in a post by Jennifer Pitt:
“This week, the Colorado River will be reunited with the sea – a destination it hasn’t seen in many years – thanks to the ‘pulse flow.’ Scientists monitoring the flow expect the two waters to meet sometime today [May 15], during high tide, but it’s actually possible that the river reached the sea last week, as we learned from a handful of adventurers who rode their stand-up paddle boards to the tidal interface.”
