Poway Returns to “Level 1” Voluntary Water Shortage Measures

The city of Poway is returning to “level 1” voluntary water shortage measures based on a report that the city has sufficient water supplies to meet its demands through June 2024, officials said.

Poway council members unanimously approved the return to less stringent water shortage measures at the Aug. 1 meeting.

Golf Course Operators Are Teaming Up to Survive Colorado River Water Cuts and a Future That’s Less Green

Golf professionals and course owners in the Southwest will meet for the first time to discuss how an industry defined by manicured grass can survive climate change, government water cuts and attract players to fairways and greens nourished with less Colorado River water.

Long-Term Drought and Near-Term Heat Wave Take Toll on Arizona’s Desert Ecology

Frank Reichenbacher worries it will soon be over for his Tumamoc globeberry — a rare Sonoran desert vine that features a fruit that looks like a tiny watermelon and tastes like dirt.

For 41 years, Reichenbacher, an associate researcher at the University of Arizona’s Tumamoc Desert Lab, has followed the same three patches of the rare plants in southern Arizona — including one on Tucson’s Tumamoc Hill.

Opinion: Despite Big Rains This Winter, Southern California Must Remain Sensible on Water Use

A reflection on the very rainy past seasons may leave San Diego County residents optimistic about the water outlook for this summer. After all, we had record rainfall levels in the southern half of California and snow falling as low as 1,500 feet, generating a snowpack of 172% of normal. It’s very easy to think a 2023 drought has been averted.

Unfortunately, headlines don’t always convey the full story. Despite the significant rain and snow that fell locally and in the northern Sierra Mountains, Southern California must continue to be judicious about continued water conservation and permanent water use efficiency.

Snowmelt Runoff Sets Streamflow Records in the Southwest

Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen.

The Other Real Reason San Diego Water World is Warring

Rage Against the Machine’s “Take the Power Back,” is quickly becoming part of San Diego’s water wars soundtrack.

The power systems at play in that tune have nothing to do with California water politics. Nevertheless, its general message aimed at challenging oppressive systems sprang to mind while I watched Valley Center Municipal Water District board meeting last month.

Snowmelt Runoff Sets Streamflow Records in the Southwest

Across the western U.S., many areas received record or near-record amounts of snowpack over the winter. With the spring and summer temperatures melting the abundant snow, a record volume of streamflow has been recorded in several basins in the southwestern U.S., providing more water for the area later into the summer than is typically seen.

Snowmelt runoff in Walker and Carson basins

The Walker and Carson basins near the California-Nevada border, for example, have reported the largest volume of streamflow for April through July that has ever been observed in roughly a century, when the records began. The ample runoff is helping fill reservoirs that have been depleted from years of drought conditions.

Weekly U.S. Drought Monitor: Cooler Northwest, Warmer Southwest

Dry conditions dominated the West and southern Plains, coupled with above-normal temperatures. Precipitation was most widespread throughout much of the upper Midwest and central Plains and into the Northeast. Almost the entire country had near- to above-normal temperatures this last week, with the greatest departures over the Southwest and central Plains where temperatures were at least 4-7 degrees above normal.

Cooler-than-normal temperatures were recorded in the Pacific Northwest with departures of 3-6 degrees below normal. At the end of the current U.S. Drought Monitor period, significant rains developed over portions of the Midwest and central Plains, and they will be accounted for in the next analysis.

U.S. Seasonal Drought Outlook

Central portions of the Intermountain West may be spared degradation, as those areas are still showing residual benefits from above normal winter snowpack leading up to the summer, in addition to periods of above normal rainfall during the last 60 to 90 days. Seasonal temperature and precipitation outlooks, ENSO, and climatology favor widespread drought improvement and removal across the central U.S. However, drought persistence is favored across the Upper Midwest, although there is the potential for localized improvements.” Read full assessment: cpc.ncep.noaa.gov/products/expert_assessment/sdo_summary.php.

Seasonal Precipitation Outlook: November, December, January 2023-24

Colors show where total precipitation has an increased chance of being higher or lower than usual during the next three months. The darker the shading, the greater the chance for the indicated condition. White areas have equal chances for precipitation totals that are below, near, or above the long-term average (median) for the next three months.

Climate scientists base future climate outlooks on current patterns in the ocean and atmosphere. They examine projections from climate and weather models and consider recent trends. They also check historical records to see how much precipitation fell when patterns were similar in the past.

Copernicus Climate Change Service: July 2023 sees multiple global temperature records broken

July 2023 highlights:

  • The global average temperature for July 2023 is confirmed to be the highest on record for any month.
  • Antarctic sea ice extent continued to break records for the time of year, with a monthly value 15% below average, by far the lowest July extent since satellite observations began.
  • July 2023 was wetter than average over most of northern Europe and in a region from the Black Sea and Ukraine to northwestern Russia. Drier than average conditions were experienced across the Mediterranean basin, with Italy and southeastern Europe having the largest anomalies.

Small San Diego Water Buyers Vie to Usurp Big City Power

Some of the region’s smaller, rural water buyers are fed up with how the city of San Diego’s been throwing its weight around recently and they see an opportunity to change things as the city scurries to stop two other agencies from defecting.

Water Wasted | The History of the Delta Water Tunnel Project and Why People Are Against It

A battle remains underway in the Sacramento-San Joaquin Valley Delta.

For decades, Delta residents and the state have been unable to agree on a plan to transport water from the rainy but rural northern part of the state down to the heavily populated, dry southern half.

22 Attorneys General Oppose 3M Settlement Over Water Systems Contamination with ‘Forever Chemicals’

Twenty-two attorneys general urged a federal court Wednesday to reject a proposed $10.3 billion settlement over contamination of U.S. public drinking water systems with potentially dangerous chemicals, saying it lets manufacturer 3M Co. off too easily.

The deal announced in June doesn’t give individual water suppliers enough time to determine how much money they would get and whether it would cover their costs of removing the compounds known collectively as PFAS, said the officials with 19 states, Washington, D.C., and two territories. In some cases the agreement could shift liability from the company to providers, they said.

“While I appreciate the effort that went into it, the proposed settlement in its current form does not adequately account for the pernicious damage that 3M has done in so many of our communities,” said California Attorney General Rob Bonta, leader of the multistate coalition.
