California has been delta tough situation

"California has a decision to make. We either brace ourselves for long-term [water] cuts that threaten our economy and our very way of way of life, or we invest in a solution to fix the [San Francisco Bay] Delta and expand our water toolbox so we can meet future challenges head-on.” Long Beach, California has become the first California city to ration water after a court decision last month (SFChron, SacBee) which may require Delta water pumping to be cut by one-third starting in December -- "the single largest court-ordered redirection of water in state history" -- to protect a tiny threatened fish called the delta smelt [resizes window]. (The court decision is not online. An earlier related decision is here.) But the situation is more complex than "drinking water versus fish." Extensive previous efforts have not succeeded in addressing the problems of the Delta, where weak levies were already barely protecting the water supply for 23 million people, a key infrastructure pipeline [pdf], and more and more people's homes [pdf]. (More technical documents here.) Will current efforts be more successful? The many possible solutions each carry their own benefits and controversies. The decision to limit the pumps will certainly draw attention to the issues and give them new urgency. The situation is so complicated, interrelated, and ever-shifting that one artist's Delta primer portrays it as a giant game of chance [pdf].

Roads To Riches (or We've Got a Bridge in Brooklyn to Sell You--Seriously) -- Why investors are clamoring to take over America's highways, bridges, and airports—and why the public should be nervous.--...a slew of Wall Street firms—Goldman, Morgan Stanley, the Carlyle Group, Citigroup, and many others—is piling into infrastructure ... Assets sold now could change hands many times over the next 50 years, with each new buyer feeling increasing pressure to make the deal work financially. It's hardly a stretch to imagine service suffering in such a scenario; already, the record in the U.S. has been spotty. ...

Breaking into the computers of a sewage plant

"[Vitek] Boden had waged a three-month war against the Scada (Supervisory Control and Data Acquisition) system of Maroochy Water Services in Australia beginning in January 2000, which saw millions of gallons of sewage spill into waterways, hotel grounds and canals around the Sunshine Coast suburb." A 2002 Washington Post story on possible al-Qaeda attacks also mentions the Boden case: "Specialists in cyber-terrorism have studied Boden's case because it is the only one known in which someone used a digital control system deliberately to cause harm."
