Corps of Engineers Considers Nature-Based Flood Control

The U.S. Army Corps of Engineers is known for damming rivers and building levees to keep waterways at bay. But a new initiative seeks natural flood control solutions as climate change brings increasingly frequent and severe weather events that test the limits of concrete and steel.

It only makes sense to use Mother Nature’s flood defenses as one of the tools to combat destruction from intense rains in the middle of the country and storms and sea level rise on the coasts, says Todd Bridges, who heads the Corps Engineering with Nature initiative.

EBMUD Begins Drawing Water From Sacramento River as Part of Drought Response

As drought conditions persist statewide, officials with the East Bay Municipal Utility District said on Monday the agency has begun tapping into water from the Sacramento River to boost local supplies.

EBMUD, which delivers water to some 1.4 million people across Alameda and Contra Costa counties, typically draws from the Mokelumne River for its water supply.

The agency said the latest move is part of its drought response.

S.F. Saw Just 9 Inches of Rain This ‘Water Year.’ Here’s How That Compares to Normal

The water year has officially come to an end — and once again, the Bay Area has come up dry.

How dry? The region received a little more than a third of normal precipitation from Oct. 1, 2020, to Sept. 30, 2021, according to data from the National Weather Service — a common occurrence for the past several years, which bodes ill for a region already at the worst “exceptional” level on the U.S. Drought Monitor map.

Drought: Marin Requests Reservoir Water for Rural Residents

As the deepening drought threatens to dry up some West Marin wells in the coming months, the county government wants to tap into dwindling reservoirs to avoid a potential public health emergency.

The county proposes to truck reservoir water for the next four months to an estimated 10 to 20 residences in areas such as Nicasio, San Geronimo Valley and Lucas Valley. The actual number of residents is not certain, county officials said, as qualification criteria are still being drafted.

Opinion: What if Farmers Really Could Use 50% Less Water? Arizona Would Be a Different Place

What if farmers could use half the water than they are now without sacrificing crop yield?

Arizona would be a different place.

There are roughly 946,000 acres of farmland in the state, according to the most recent federal farm census in 2018, using an estimated 4.4 million acre-feet of water.

What is La Niña ?

The term La Niña may be one that casual weather observers as well as aficionados hear meteorologists using from time to time, especially when breaking down long-term weather trends or providing a sneak peek at conditions expected during an upcoming winter or hurricane season. But, what exactly is La Niña? Let’s take an in-depth look.

The key to how winter in the United States may unfold often lies thousands of miles away in the open waters of the equatorial Pacific Ocean. It’s there where the roots of a climatological phenomenon known as La Niña originate and eventually help shape weather patterns worldwide.

Opinion: How California Can Solve Its Growing Water Crisis

With snowpack and storage at historic lows, California and 95% of the West are suffering the worst drought in modern history. Marin and Santa Clara counties have imposed mandatory cutbacks, and other counties are considering the same. However painful, it is time for California to move quickly. Here are the steps — starting with the least intrusive and least expensive — that state and local government need to take now to avoid the dystopia that Cape Town, South Africa, endured in 2018 when the faucets ran dry.

Opinion: Happy New Water Year — Californians Have to Face Some Difficult Wet Season Truths

Happy New Water Year. For those of us who work on California water challenges, the start of the new year isn’t Jan. 1; it’s Oct. 1, the official beginning of the state’s wet season. This is the time of year we start to look out over the Pacific for the storms we hope will bring life-giving precipitation, replenishing our rivers and streams, coating our mountains with snow, refilling our reservoirs and recharging our soils, forests, wetlands and groundwater.

Why Southern California is Generally Better Prepared for Drought Than Northern California

Northern California receives more annual rain and snow than Southern California, with 75% of the state’s precipitation falling in the watersheds north of Sacramento. Yet amid a drought, it seems people in the north are conserving water by letting their lawns turn brown and taking shorter showers as districts and municipalities impose mandatory water-use restrictions, while urban areas of the arid south are lush and green with well-watered gardens and lawns.

Calif. Regulators Buckle Up for the Potential of 0% Water Allocation for 2022

California’s reservoirs are so dry from a historic drought that regulators warned Thursday it’s possible the state’s water agencies won’t get anything from them next year, a frightening possibility that could force mandatory restrictions for residents. This year, unusually hot, dry conditions caused nearly 80% of that water to either evaporate or be absorbed into the parched soil — part of a larger drought that has emptied reservoirs and led to cuts for farmers across the western United States. It caught sate officials by surprise as California now enters the rainy season with reservoirs at their lowest level ever.
