Work Continues On The Oroville Dam Main Spillway

Construction continues on the Oroville Dam’s main spillway this week. The Department of Water Resources has been working to reconstruct the the main spillway which was damaged in February because of heavy winter rain. Crews with Kiewit Corp., the lead contractor on the job, are working around the clock to rebuild enough of the main spillway in time for next rainy season. The deadline for the rebuild is Nov. 1. A study by an independent forensic team found that poor design and construction in the 1960s led to the failure of the spillway.

OPINION: Water Policy Leaves California Vulnerable

Water is the Central Valley’s economic lifeblood — of that, there is no doubt. The drought of the last five years has put tremendous pressure on the state’s water allocation systems and shown that they are not only broken but incapable of adapting to the realities of a sustained drought cycle. But, why should people in Southern California and Orange County care if water is not available to the Central Valley and agricultural production goes away?

 

The US Has a Vast, Untapped Supply of Renewable Energy That’s Neither Wind, Solar, or Hydropower

The value of water as a liquid is obvious. We can drink it, use it to clean ourselves and our things, swim in it to cool off and to play, and build dams across it to harvest its energy. Water as clouds are also essential: they are key for the way they deliver precipitation to cropland and forests. But scientists now say we may have been overlooking the most useful stage of the water cycle.

Private Water Firms Tap Profit From Struggling Public Utilities

A cash crunch for public water utilities is creating an opportunity for the growing for-profit water companies—but it’s one that might drain customers’ wallets. Companies like American Water Works Co. and Aqua America Inc. are finding the time is right to purchase small, troubled water utilities from local governments that are facing political pressure to keep rates low—often by delaying infrastructure upgrades. Acquisitions like these are helping private water companies grow even while per capita water consumption continues its long-term downward trend.

Clogged Tunnels? North Delta Towns Stay Guarded After Financial Setback for Twin Tunnels

The water project that north Delta communities fear will end their way of life may have met its own ending, after the plan to finance it collapsed unexpectedly in a Central California boardroom last week.

News of the twin tunnels’ setback came September 20, when the Westlands Water District, which serves farms in Fresno and King counties, voted not to participate in financing its share of the $17 billion project. The WWD’s manager told the Sacramento Bee that signing on would cause too much monetary pain. The district was expected to pay roughly $3 billion.

OPINION: Watershed Conservation Key to Solving California’s Water Problems

The California Water Fix/delta tunnels project is facing new challenges every day, most recently in regard to financing. Whether or not the state’s water suppliers support the plan, an essential piece is missing from the conversation: the potential of the state’s watersheds — the forests, meadows and streams that deliver water to our dams — to help solve California’s water problems.

US, Mexico Share Benefits and Burdens in New Colorado River Pact

A new, U.S.-Mexico agreement provides more Colorado River water to both countries, will require both countries to share inevitable river shortages and offers more certainty as to how much river water will be available for both countries. That’s how negotiators, federal officials and Arizona water officials see the upshot of the pact that was signed this week at a Santa Fe, New Mexico, ceremony following years of negotiations. The agreement, known as Minute 323, is aimed at establishing ground rules for managing the river for the two countries through 2026.

A New Fight Over Water In The California Desert, With Echoes of ‘Chinatown’

Beside the winding curves of the Colorado River, the Palo Verde Valley spreads out in a lush plain in the middle of the desert, a farming oasis filled with canals and fields of hay. For 12 years, the valley’s farmers have been participating in a program that pays them to leave some of their lands unplanted and fallow, helping to slake the thirst of Los Angeles and cities across Southern California. The arrangement has been widely praised as a model of how cities and farming areas can work together to stretch water supplies further while keeping agriculture alive.

Humboldt County Records Highest Rainfall on Record Since 1903-04

Humboldt County recorded its third highest rainfall total in the 2016-17 water year since records first began 130 years ago, according to the National Weather Service Eureka. The downpour caused tens of millions of dollars in damage to local infrastructure and seemingly failed to produce the beneficial effects to fish and wildlife on the Klamath River that some were hoping for. Nearly 64 inches of rain were recorded at the weather service’s Woodley Island station from the start of the water year on Oct. 1, 2016, through Wednesday.

This Snap-On Sensor Could Tell Farmers Exactly How Much To Water Their Crops

The system, for which the Penn State Research Foundation has applied for an international patent, features a clip-on unit that contains sensors to detect the thickness and electrical capacitance, or the ability to store a charge, of individual leaves. The array of sensors is connected to a WiFi node, which transmits the data to a central unit that tracks the measurements over time and uses them as indicators of water stress. Eventually, a smartphone app could run the whole system.
