Forty Atmospheric Rivers Have Hit West Coast Since October

More than three dozen atmospheric rivers made landfall on the West Coast from fall through early spring, but a lack of strong events in California led to the development of drought conditions in parts of the state.

An atmospheric river is a thin, but long plume of moisture in the atmosphere that stretches from the Pacific Ocean tropics or subtropics into higher latitudes. They provide a boost to the rain and snow totals produced by storm systems taking aim at the West Coast, mostly from late fall into early spring. Although these events can bring hazardous impacts, they are also beneficial since they help replenish the water supply in the West.

Water Utilities May Face Virus-Linked Protective Gear Shortages

Nearly three in four water and wastewater treatment plants are worried about running out of masks, gowns, and gloves to protect workers from the deadly coronavirus, according to a survey of utilities.

The survey, released late Tuesday, reveals that the same proportion of utilities are also concerned about being able to keep workers 6 feet apart at all times to prevent transmission of the virus that causes Covid-19.

The findings are a snapshot of the concerns a subset of the nation’s water and wastewater utilities shared with the nonprofit American Water Works Association, which conducted the survey March 25-30. Responses came from 532 utilities, and the margin of error was plus or minus 4 percentage points.

With the nation grappling to keep the coronavirus pandemic in check, clean and safe running water for washing hands and other cleaning has been deemed an essential service.

Lawsuits Vowed as Feds, California Take Divergent Water Routes

California’s decision to depart from federal regulations when managing its water supplies is causing strife across the water world.

The state recently got a new permit for water delivery operations from its wildlife agency. In the past, that kind of authority came from adhering to federal rules. Now, with a dispute between the state and federal government over water management and endangered species act protections, the state issued its own permit.

Critics of the state’s move say they plan to file lawsuits. Different detractors say the rules are too stringent, or too weak.
