Topic: Central Valley


Central Valley

The Central Valley is a vital agricultural region that dominates the center of California, stretching 40-60 miles east to west and about 450 miles from north to south.  It covers 22,500 square miles, about 13.7% of California’s total land area.

Key watersheds are located here: The Sacramento Valley in the north, San Joaquin Valley and Tulare Basin to the south. In addition, the Sacramento and San Joaquin rivers drain their respective valleys and meet to form the Sacramento-San Joaquin Bay Delta, which flows to the Pacific Ocean via the San Francisco Bay.

Explainer: How cities in the West have water amid drought

As drought and climate change tighten their grip on the American West, the sight of fountains, swimming pools, gardens and golf courses in cities like Phoenix, Las Vegas, Los Angeles, Salt Lake City, Boise, and Albuquerque can be jarring at first glance. Western water experts, however, say they aren’t necessarily cause for concern.

California hikes costs for flood protections in farm country

Climate change is worsening the already significant threat of flooding in California’s farm country, and state officials said Thursday that as much as $30 billion may be needed over three decades to protect the region, an increase from five years ago. Every five years, flood protection plans are updated for the Central Valley, where about 1.3 million people live at risk in floodplains. State officials released a draft of the latest update that calls for investing in levees, maintenance and multi-benefit projects that recharge aquifers and support wildlife while enhancing flood protection.

California Senate OKs lower standard for indoor water use

Mired in an extreme drought, California lawmakers on Thursday took the first step toward lowering the standard for how much water people use in their homes — a move that won’t be enforced on individual customers but could lead to higher rates even as consumption declines. California’s current standard for residential indoor water use is 55 gallons per person per day…. The California Senate voted 28-9 on Thursday to lower the standard to 47 gallons per person per day starting in 2025; and 42 gallons per person per day beginning in 2030. The bill has not yet passed the Assembly, meaning it is still likely months away from becoming law.

Land and waterway managers labored hard over the course of a century to control California’s unruly rivers by building dams and levees to slow and contain their water.

SIDEBAR: Creating A Floodplain Buffet for Salmon Smolts

Biologists have designed a variety of unique experiments in the past decade to demonstrate the benefits that floodplains provide for small fish. Tracking studies have used acoustic tags to show that chinook salmon smolts with access to inundated fields are more likely than their river-bound cohorts to reach the Pacific Ocean. This is because the richness of floodplains offers a vital buffet of nourishment on which young salmon can capitalize, supercharging their growth and leading to bigger, stronger smolts.

A government agency that controls much of California’s water supply released its initial allocation for 2021, and the numbers reinforced fears that the state is falling into another drought. The U.S. Bureau of Reclamation said Tuesday that most of the water agencies that rely on the Central Valley Project will get just 5% of their contract supply, a dismally low number. Although the figure could grow if California gets more rain and snow, the allocation comes amid fresh weather forecasts suggesting the dry winter is continuing. The National Weather Service says the Sacramento Valley will be warm and windy the next few days, with no rain in the forecast.

A water recharge basin in Southern California's Coachella Valley. To survive the next drought and meet the looming demands of the state’s groundwater sustainability law, California is going to have to put more water back in the ground. But as other Western states have found, recharging overpumped aquifers is no easy task.

Successfully recharging aquifers could bring multiple benefits for farms and wildlife and help restore the vital interconnection between groundwater and rivers or streams. As local areas around California draft their groundwater sustainability plans, though, landowners in the hardest hit regions of the state know they will have to reduce pumping to address the chronic overdraft in which millions of acre-feet more are withdrawn than are naturally recharged.

Floodplains in California

With the dual threats of obsolete levees and anticipated rising sea levels, floodplains—low areas adjacent to waterways that flood during wet years—are increasingly at the forefront of many public policy and water issues in California.

Adding to the challenges, many floodplains have been heavily developed and are home to major cities such as Sacramento. Large parts of California’s valleys are historic floodplains as well.

Pacific Flyway

The Pacific Flyway is one of four major North American migration routes for birds, especially waterfowl, and extends from Alaska and Canada, through California, to Mexico and South America. Each year, birds follow ancestral patterns as they travel the flyway on their annual north-south migration. Along the way, they need stopover sites such as wetlands with suitable habitat and food supplies. In California, 90 percent of historic wetlands have been lost.

Mendota Pool

The Mendota Pool, located at the confluence of the San Joaquin River and Kings River in California’s Central Valley, is the terminus of a long journey for water from the Sacramento River.

After being diverted, the Sacramento River water heads south from the Sacramento San Joaquin Delta via the 117-mile long Delta-Mendota Canal.

Environmental Issues and Water

Environmental concerns have closely followed California’s development of water resources since its earliest days as a state.

Early miners harnessed water to dislodge gold through hydraulic mining. Debris resulting from these mining practices washed down in rivers and streams, choking them and harming aquatic life and causing flooding.

Central Valley Wetlands and Riparian Habitat

In the Central Valley, wetlands—partly or seasonally saturated land that supports aquatic life and distinct ecosystems— provide critical habitat for a variety of wildlife.
