The Sacramento-San Joaquin Delta is 435 miles from South Orange County, but the impact of what happens there is felt as close to home as your shower. The Delta is the heart of the State Water Project. Near Stockton, the Delta is where the tidal forces of the Pacific Ocean meet the outflows of the Sacramento and San Joaquin rivers. Water flows through the Delta before entering a series of reservoirs, pumps and canals that bring water from the Sierras to Southern California.

The San Diego County Water Authority celebrated Tuesday its award for the world’s top civil-engineering project — a network of dams, pumps and pipelines that can protect the region’s water supply for six months. The $1.5 billion Emergency & Carryover Storage Project received the 2017 award from the American Society of Civil Engineers earlier this year, beating out the iconic new One World Trade Center in New York and the Chhatrapati Shivaji International Airport Terminal 2 in Mumbai, India, among other projects. On Tuesday a plaque was officially unveiled at the remote Olivenhain Dam, one of the four key parts of the project.

After weeks of back-and-forth between environmentalists and business interests, Gov. Jerry Brown and legislative leaders introduced a proposal Monday evening to reauthorize California’s cap-and-trade program, the centerpiece of the state’s efforts to battle climate change. The plan consists of two bills: Assembly Bill 398, which would extend the life of the program until 2030 and modify how the cap-and-trade market operates, and AB 617, which aims to address concerns about air quality in communities by increasing monitoring and imposing stricter penalties on polluters.

Southern California will enjoy a brief respite from record-breaking temperatures for the next few days, but it probably won’t feel like it. High humidity will bring muggy and sticky conditions to the Southland this week, while a band of moisture could generate thunderstorms in the deserts, according the National Weather Service. On Monday, scattered showers will move throughout Los Angeles County and could bring dangerous lightning and flash flooding in the mountains and deserts, forecasters say. Temperatures will drop by 4 to 8 degrees in Los Angeles County and Ventura County on Monday and Tuesday.

When the San Diego County Water Authority filed its initial rate case lawsuit in 2010 against the Los Angeles-based Metropolitan Water District of Southern California, we knew it would be a marathon. Seven years later, we passed another important marker in the long-running litigation when a June 21 ruling by the state Court of Appeal sided with the Water Authority and the San Diego region on several significant issues. The decision includes a few key takeaways: The Water Authority has a right to significantly more water from MWD than MWD had credited.
