Is Valley Drought Back? 2018 Ends As A Drier-Than-Normal Year

/in , /by /The Fresno Beeby Tim Sheehan

In a state where dead trees in the Sierra Nevada still stand as a testament to a severe seven-year stretch of dry weather that ended in 2017, some nervously wonder whether the state may slide back into a drought. In the eastern Pacific Ocean near the equator, ocean temperatures are pretty stable. That means there’s no El Niño or La Niña sitting out there to help drive a chain of storms to dump rainfall on the Valley and snow in the Sierra Nevada as the calendar closes on 2018.

OPINION: State’s New Voluntary Water Agreements Are A Good Deal For Delta Fish, Valley Farms

/in , /by /The Fresno Beeby Thomas Birmingham and Jason Phillips

Over the past three years, the State Water Resources Control Board has conducted a public process to increase the water flowing to the Sacramento-San Joaquin Rivers Delta with the intent of improving declining fish populations. However, an increase in river flow means a reduction in supplies for Californians, who are dependent on them for their lives and livelihoods. There are two approaches to this: painful, mandatory cuts to water supplies or voluntary agreements among water users to achieve specific goals in the Bay-Delta Water Quality Control Plan update.

OPINION: What New Water Deals Mean And What Work Is Left To Be Done

/in , /by /CALmatters (Sacramento)by Karla Nemeth

California’s State Water Project and federal Central Valley Project span several northern watersheds, converging in the Sacramento-San Joaquin Delta, where their pumping stations operate a stone’s throw away from one another. They coordinate their operations on a daily basis and have done so for decades. Earlier this month, the California Department of Water Resources signed three agreements updating how the state and federal projects share  environmental and financial obligations associated with their operations.

Trump’s Rule A Wild Card For Western Water Supplies

/in , /by /E&E News (DC)by Ariel Wittenberg and Jeremy P. Jacobs

The Trump administration’s proposal to limit the Clean Water Act’s reach over wetlands and waterways would likely complicate efforts to protect and manage the parched West’s most important and imperiled source of water. At risk: the Colorado River — water provider for 40 million people and vast swaths of cropland — which is already reeling from a crippling drought and rising water demands. Trump’s proposed waters of the U.S. (WOTUS) rule would strip federal protections for ephemeral streams that only flow after rain or snow and wetlands without continuous surface water connections to waterways. That’s particularly important in the Colorado River Basin.

The Department of Water Resources (DWR) yesterday released the Public Review Draft of the California Water Plan Update 2018. The draft plan presents a vision for greater collaboration in water management, with a focus on achieving long-term sustainability and improvements to public health, the economy, and the environment. The California Water Plan is the state’s comprehensive strategic plan for managing and developing water resources sustainably. DWR publishes a plan update every five years, as directed by California Water Code.

OPINION: A Long-Term Solution To California’s Water Woes

/in , /by /Whittier Daily Newsby Marc Joffe

After years of drought and the recent devastating wildfires, Californians have been frequently reminded of water’s key role in everything from subduing the tragic blazes to its continuous uses for key agriculture, residential and commercial needs across the state. In the past, California has battled shortages and water challenges by rationing. But Israel has shown there may be a better long-term solution. Like California, Israel has an arid climate. Unlike the Golden State, Israel has solved its water shortage by commissioning a series of privately built and operated seawater desalination plants.

Warming Winters And Dwindling Sierra Nevada Snowpack Will Squeeze Water Resources In Parts Of California, NOAA Reports

/in , /by /Sierra Sun Timesby Michon Scott

Snowmelt from the Sierra Nevada Mountains provides roughly 75 percent of California’s agricultural water, and 60 percent of Southern California’s water resources. Warm winters can cause snow droughts in the Sierra Nevada, both by nudging precipitation in the direction of rainfall rather than snowfall, and by melting snow sooner. A new study by researchers at the University of California, Irvine, uses historical records and modeling to understand how the Sierra Nevada snowpack may respond to rising temperatures. Based on the new study, this figure shows how the snowpack could fare in the Sierra Nevada with a 1°C (1.8°F) increase in average winter air temperature.

Democrats’ House Takeover Could mean Big changes For California Water Policy

/in , /by /Los Angeles Timesby Sarah D. Wire

Among the changes ahead when Democrats take control of the House in January, add this one: The switch will upend the balance of power in California’s water wars. In the two years since Republicans’ 2016 election triumphs, party members from the Central Valley led by the current House majority leader, Rep. Kevin McCarthy of Bakersfield, have gotten several water bills for their area through Congress. Those included the first significant California-specific policy in decades, as part of the Water Infrastructure Improvements for the Nation Act, also called the WIIN Act.

As Colorado River Stakeholders Draft A Drought Plan, The Margin For Error In Managing Water Supplies Narrows

/in , /by /Water Education Foundation (Sacramento)by Gary Pitzer

As stakeholders labor to nail down effective and durable drought contingency plans for the Colorado River Basin, they face a stark reality: Scientific research is increasingly pointing to even drier, more challenging times ahead. The latest sobering assessment landed the day after Thanksgiving, when U.S. Global Change Research Program’s Fourth National Climate Assessment concluded that Earth’s climate is changing rapidly compared to the pace of natural variations that have occurred throughout its history, with greenhouse gas emissions largely the cause.

How Best To Share The Disappearing Colorado River

/in , /by /High Country News (Paonia, Colo.)by Paige Blankenbuehler

As early as 2020, hydrologists forecast that the level of Lake Mead, the largest reservoir on the Colorado River, could drop low enough to trigger the first water shortages in its downstream states of Arizona, Nevada and California. The three states in the river’s Lower Basin have long feared shortages. But the continued decline of Lake Mead reflects a reality they can no longer ignore: Demand for the river’s water, which supports 40 million people from Wyoming to California, has long outpaced the supply.
