The case for a BDCP with no tunnels:  In Sunday’s Sacramento Bee, Dr. Jeff Michael makes the case for a BDCP without the tunnels, and follows it up with a few other points over at the Valley Economy blog.  Bottom line, says Dr. Michael:  ” … The BDCP has ignored a number of viable and less costly no-tunnel alternatives.  As today’s op-ed said, a reasonable conclusion from their own studies is that simply removing the tunnels from the current BDCP is almost certainly better than the tunnels plan.  The BDCP study also found that a plan with super extensive modifications to Delta channels is better than the current plan.  In light of this evidence from their own reports, the continued tunnel vision of BDCP is inexcusable.  … ”  Click here for the Sacramento Bee commentary; click here for the Valley Economy blog.

The Economist’s Babbage blog wanders through the Delta in a piece that talks about many things, including the levees, likening an earthquake-induced massive levee failure in the Delta to Katrina:  ” … Local interests label all talk of levee failure as scaremongering. There have been numerous major earthquakes over the years, they argue, but no catastrophic collapse of the Sacramento-San Joaquin River Delta’s defenses. They point to seismic testing done on Sherman Island in 2011 that failed to breach a levee and precipitate a flood. Only 100 or so of the delta’s levees have failed since the 1890s.  All true. But the past is no guide. The biggest difference today is climate change, which is already affecting the physical and ecological structure of the delta. Freshwater runoff from precipitation and melted snow is now expected earlier in the season than ever, and in more sporadic and unpredictable quantities than before. … ”  Read more from the Babbage blog here:  Difference Engine: From torrent to trickle

The BDCP answers more questions:  How will the government shutdown affect the release of the documents?  How will the BDCP address climate change in the Delta?  What about upstream reservoirs and ‘dead pool’ conditions and impacts on groundwater in the Delta?  The latest update to the BDCP’s Q&A page answers these questions and more.  Read more here:  Your questions answered

The Public Water News Service’s Burt Wilson lays out the science for the Delta Science Program:  ” … Now, believe-it-or-not, I respect science as long as it maintains its independence and integrity and does not bow down to pressures emanating from the governor’s office, the state NRA or the DSC or the BDCP.   It is in that respect that I will now provide the Independent Science Board with scientific evidence of how the Delta and its habitat became degraded and how it was subsequently restored to a healthy state. And, not so incidentally, they can become the heroes of the Delta.  … ”  Read more from the Public Water News Service here:  Can Delta Science work for the   Delta instead of the BDCP?

What about Southern California and desalination?  The BDCP blog takes a look at why desalination isn’t really an alternative to the BDCP:  ” … Today, MWD provides on average more than 1 million acre-feet of water a year from the State Water Project to cities from Ventura to San Diego. Stripping salt from ocean water takes huge amounts of electricity, and ocean-desalting plants must be located along the coast. To replace half of the water MWD gets each year from the Delta through the State Water Project would require construction of approximately a dozen plants the size of the Carlsbad facility in the MWD territory – about one every 13 miles along the coast from Malibu to San Diego.   To bring potable water from the coast also would require MWD to install pumping plants throughout its territory. The district now distributes water by gravity, with water flowing downhill from east to west toward the coast. … ”  (By the way, what the BDCP blog doesn’t mention is that pipes and infrastructure that distribute the water throughout the urban area get smaller as they deliver the water and approach the coast.  Metropolitan’s Bill Hasencamp said that taking in a large volume of water at the coast would be much like trying to get a blood transfusion through your little toe.)  More from the BDCP blog here:  What about desalination?

The economic impact of one crop:  Recently, a group came together in a field of alfalfa to show the economics of a single crop grown in the San Joaquin Valley:  ” … It was a demonstration on how, without the alfalfa, due to reduced water allocations, there are major impacts on business and humans. The gathering of equipment, suppliers and even cows became an aerial photo, and video that will be publicized on different websites, YouTube and in other print and electronic mediums. “It is our responsibility to tell our story so that this information goes on record in the form of a unique photograph, which we hope to turn into billboard messaging,” said [Westlands Water District’s Gayle] Holman. … ”  More from California Ag Today: Industry Gathers In Alfalfa Field to Show Why We Need Water

“Water conservation ethic” recommended for San Diego:  A task force formed in 2012 to recommend ways to implement San Diego’s 2011 water policy has released their report, which makes several recommendations, including establishing an ongoing program to create a “water conservation ethic” among the general public.  Read more from GrokSurf’s San Diego blog here:  “Water conservation ethic” recommended for San Diego
