So much for a “drought-busting” El Niño winter in California. While the warming of the equatorial Pacific waters (known as the Oceanic Niño Index or ONI) was one of the strongest on record, California unfortunately did not enjoy the plentiful rains that many expected. Atmospheric conditions steered storms to the Pacific Northwest and away from Southern California, much to the surprise of many meteorologists. As a result, Seattle officially experienced its wettest winter in recorded history. In California, tests conducted last week showed that the state’s overall snowpack was less than average. While the 2016 spring survey was markedly better than one year ago, (Governor Jerry Brown stood on a bare meadow exactly one year ago – it was the first and only time since 1950 that there was no snow at the Phillips Station site on this date) snow at the site totaled 58.4 inches, just 97% of average. Statewide snow totals average just 87% of average for this date. The snow totals in the state decrease the further south you go. While the Northern Sierra has a 97% of average snowpack, the Central Sierra has 88% and the Southern Sierra only 72%. Continue reading

El Niño Is Not Treating All of California Evenly
In August 2015, forecasters predicted that a “Godzilla El Niño” would be heading to the western United States, potentially wiping out (or at least putting a major dent) in the widespread drought. Meteorologists pointed to the similarities between the ocean warming in 1997 and the pattern seen last summer. So far, the forecasters correctly predicted that the El Niño warming patterns would continue to build and rival the intensity of the 1997-1998 El Niño. But unfortunately for the drought in the western United States, the El Niño ocean warming patterns have not translated into significantly above average rainfall totals. After series of promising storms in January, a warm and dry February provided little relief to the drought. At the beginning of February, the US Drought Monitor reported that 39.41% of California faced exceptional drought conditions. At the last update on March 8th, 38.48% of the Golden State had exceptional drought, a reduction of less than 1%. Continue reading
What is the Environment Telling us About the Water Situation in the West?
This year’s Groundhog Day was symbolic in more ways than one. When Punxsutawney Phil emerged from his burrow on February 2nd, he did not see his shadow and predicted an early spring. In the Southwest US, his prediction has so far come true. Despite early hopes in January that the strong Pacific El Niño would help bring an end to the drought, February has so far been a bust. The National Weather Service reports that globally, January 2016 was the hottest on record and that temperatures across the Southwestern US reached records. In some parts of California and the desert Southwest, temperatures have been between 15 to 25 degrees hotter than average. As the temperatures have risen, precipitation amounts have fallen. While forecasters believe that the storms may return with some intensity in March, a ridge of high pressure has come into place that blocked storms from tracking through California and the Southwest US. These patterns are reminiscent of the El Niño predictions in 2014 and 2012 that never showed up. But unfortunately, much like Bill Murray’s character woke up to the same day over and over again, the California remains in the midst of exceptional drought conditions month after month.

Beyond Flint: The Future of Water Quality Issues in the United States
In my last post, I wrote about how the water problems in Flint, Michigan may not be an isolated incident in the United States. While a series of missteps and mismanagement led ultimately to the water crisis in Flint, the situation there highlights a much greater problem in the United States: We have generally under-invested in our water infrastructure, and water quality may continue to suffer in other parts of the nation as a result. The water system in Flint has pipes in it that are in some instances 100 years old, and many main lines contain lead. But Flint is hardly alone in facing the problems that aging infrastructure cause. Cities on both coasts, from Washington, D.C., Philadelphia, Chicago, and Los Angeles all have lead and cast iron pipes in the ground that will need to be replaced. In 2013, the American Society of Civil Engineers (ASCE) created a US infrastructure “report card” which assigned grades to a host of infrastructure types. ASCE’s report was not kind to the various water categories. Drinking water, waste water and dams got “D” ratings, and our levees got a “D-“ rating. The report estimates that the drinking water system alone will take $1 trillion in investment to bring the US as a whole up to a satisfactory level of service. Continue reading
