By James R. Riordon 17 June 2024 (NASA GSFC) – Record snowfall in recent years has not been enough to offset long-term drying conditions and increasing groundwater demands in the U.S. Southwest, according to a new analysis of NASA satellite data [Snowfall Replenishes Groundwater Loss in the Great Basin of the Western United States, but […]
By Tom Philpott4 August 2014 (Mother Jones) – Science papers don’t generate much in the way of headlines, so you’ll be forgiven if you haven’t heard of one called “Groundwater Depletion During Drought Threatens Future Water Security of the Colorado River Basin,” recently published by University of California-Irvine and NASA researchers. But the “water security […]
By Brett Walton7 July 2014 (EcoWatch) – 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. The record-setting low […]
Wet Desert Expeditions7 February 2011 Every year around this time I start to hear comments along the lines of “I heard the lake is supposed to go up 20 feet this winter” or “I was at the lake this weekend and it was up 10 feet!” I call this period the Winter Bump, where for […]
By Bryan Walsh February 10, 2011 It’s not the heat that might get us with climate change—it’s the humidity, so to speak. The risk of sea level rise due to melting land ice is one of the most recognized—if controversial and hard to predict—threats posed by global warming. Other potential impacts from global warming include […]
By HENRY BREAN, LAS VEGAS REVIEW-JOURNALJanuary 6, 2011 | 12:00 a.m. A flood that destroyed homes near Mesquite last month also delivered a welcome boost to Lake Mead. High flows on the Virgin River and its tributaries raised the level of the reservoir by about a foot and a half, according to rough projections from […]
Federal forecasters say it is likely that Lake Mead will receive a larger than usual release of water from Lake Powell in the coming year, as conditions in the two reservoirs approach a trigger point for so-called “equalization.” The extra water for Lake Mead — 9 million acre-feet instead of the standard 8.23 million acre-feet […]
By Rebecca Kimitch, Staff Writer, rebecca.kimitch@sgvn.com Posted: 12/24/2010 10:21:50 PM PST The storms that brought flooding and destruction to the region last week had something of a silver lining, at least to water managers. The rains went a long way to refueling water supplies that were precariously low after three years of drought. More than […]
By Lauren Morello and ClimatewireDecember 14, 2010 A 60-year drought that scorched the Southwest during the 12th century may be a harbinger of things to come as greenhouse gases warm the Earth, according to research published yesterday in the Proceedings of the National Academy of Sciences. The study’s authors used tree rings to reconstruct a […]
By FELICITY BARRINGEROctober 18, 2010, 2:05 pm Sometime between 11 and noon on Sunday, the water level in Lake Mead, the massive reservoir whose water fills the taps of millions of people across the Southwest, fell lower than it ever has since it was filled 75 years ago. Even as a flurry of thunderstorms dropped […]
