Drought Hitting Home in California, Arizona

As drought deepens in the West and the water used by farms and people alike dwindles, farmers in Arizona and California are bracing for cutbacks in the two major federal systems that supply irrigation and drinking water to millions of people.

Water storage is shrinking with no snowpack to replenish reservoirs managed by the Bureau of Reclamation in California and Arizona. Shasta Lake in northern California is about half full while lakes Mead and Powell, the two giant reservoirs designed to contain more than 50-million-acre feet of water behind Hoover and Glen Canyon dams, respectively, are precariously low with under 20-million-acre feet of total storage combined.

Drought Conditions Worsen in California After Prolonged Warm, Dry Weather

Ventura County has moved into severe drought conditions as it wraps up what is typically the rainiest months of the year.

Opinion: Silver Lining to Water Woes Could be Farmers Putting Their Lands to New Uses Besides Crops

The Central Valley has reached a critical juncture.

On one path, without proactive, collaborative planning, the Valley could become a haphazard patchwork of dusty fields infested with invasive weeds and pests, further impairing already poor air quality, devastating the agricultural economy and putting many farmworkers out of work.

On another path, the Valley can remain a thriving agricultural region amid a mosaic of new land uses, like vibrant habitat corridors for the endangered San Joaquin kit fox or wildlife-friendly groundwater recharge areas for migratory birds or outdoor recreational green spaces for families.

Water Year 2021 Characterized by Persistent Dry Weather and Worsening Drought in California

• Total precipitation has been well below normal throughout much of California during water year (WY) 2021
• In some regions, drier than normal conditions extend back to the start of WY 2020
• Drought has expanded and intensified across the state, and current water storage levels are below normal in many
reservoirs
• Below-normal snowpack in the Sierra Nevada may limit water resource availability as summer approaches
• The abnormally dry conditions were driven by a lack of landfalling atmospheric rivers (ARs) and persistent
ridging/blocking over the Northeast Pacific Ocean
• Drought is expected to continue through spring 2021, thereby increasing the threat of significant wildfire activity in
summer 2021

Marin Municipal Water District Proposes Mandatory Conservation

The Marin Municipal Water District is proposing mandatory conservation rules for the first time since 1988 in response to record-low rainfall levels akin to those of the notorious 1976-77 drought. The proposed ordinance would require customers to limit outdoor watering to one day per week starting May 1 and adhere to other restrictions. The district board of directors plans to vote on the ordinance on April 20. The district has received just 20 inches of rain this year, its second-lowest amount in 143 years of records. The lowest was 18 inches in 1924.

Water Authority Says No Water Shortage, Despite Dry Conditions Throughout West

The San Diego County Water Authority is developing a water shortage contingency plan, though not implementing it, despite dry conditions in places from which the region imports much of its water.

The region draws about 20% of its water from local sources, including groundwater, desalinated seawater and local reservoirs, according to the Authority’s website. Fully one-half of regional water is imported, by various means, from the Colorado River. A minority proportion comes from Northern California.

Third-Driest Year Reported in California

The California Department of Water Resources has marked 2021 as the third-driest water year, a period marked from October to March, on record for the Golden State, potentially setting up another deadly wildfire season after last year’s record setting blazes.

Watershed Survey Helps Maintain San Diego Regional Water Quality

The City of San Diego Public Utilities Department conducts regular surveys of its watersheds to monitor and maintain high water quality within those watersheds. The City recently released its 2020 Watershed Sanitary Survey. Conducted and issued every five years since 1996 as required by California law, the report identifies actual or potential causes of local source water contamination that might adversely affect the quality and treatability of City of San Diego water.
