Colorado River Drought Agreements Part II: Minute 32x and US-Mexico Relations on the Colorado River

Relations between the United States and Mexico were of particular focus on Donald Trump’s presidential campaign. Whether discussing the border wall, revisions to NAFTA or drug enforcement policies, Mexico was a repeated and at times controversial topic of discussion. Strains over US-Mexico relations reached a focal point shortly after President Trump was inaugurated when Mexican President Enrique Peña Nieto cancelled a White House Visit scheduled for January 27th after President Trump demanded Mexico pay for the estimated $12-15 billion completion of the proposed border wall.

Negotiations on the Colorado River Part I: Despite Low Drought Figures, Colorado River Basin States Must Remain Vigilant

What is missing from the map of the United States right now? Well in general, drought is missing. According to a recent US Drought Monitor, the contiguous United States had the lowest reading of overall drought in the 17 year history of the weekly service. For the week of May 2nd, only 4.98% of the contiguous US had some form of drought. According to the USA Today, the lowest prior reading for the US was 7.7% of the US in drought, set in July 2010. It also compares favorably to a record high of 65.5% of the US in some form of drought set in September 2012. Continue reading

With Full Reservoirs and a Deep Snowpack, Why did the Central Valley Project Initially Hesitate to Deliver 100% Entitlement to each Contractor?

Looking at the current reservoir conditions from the California Data Exchange Center, it is clear to see that the conditions in California are much different than from a year ago. Nine of the state’s major reservoirs that serve both the Central Valley and State Water Projects have over 100% of their historic averages for this date. The state’s two largest reservoirs, Lake Shasta and Lake Oroville are at 96% and 84% full respectively. The San Francisco Chronicle published a series of before and after photos of reservoirs in the state to show the stunning change in hydrologic conditions in just one year. For example, in August 2016, the San Luis Reservoir outside of Los Banos was at 10% of capacity. Fast forward to today, and the reservoir is completely full. The much-improved hydrologic conditions prompted Governor Jerry Brown on April 7th to issue an executive order that lifts the drought emergency in all California counties except Kings, Tulare, Fresno and Tuolumne. The drought emergency he rescinded had been in place since April 25, 2014. Continue reading

The Water Haves and Have-nots in the Winter of 2017

In my last post, I wrote about how long-suffering California is having a good start to the water year as weather patterns have changed and so far, ample rainfall has fallen across the Golden State. A series of powerful storms this weekend and continuing this week has already caused flooding and widespread damage across parts of California. In Sacramento, Monday marked the first time in ten years that officials opened the Sacramento Weir to divert floodwaters to the Yolo Bypass and prevent further damage downstream. Strong winds also toppled the iconic Pioneer Cabin Tree, a hollowed-out sequoia large enough for cars to drive through. Further “atmospheric river” storms are expected to hit across the state as the week continues.
