The start of California’s annual rainy season has been pushed back from November to December, prolonging the state’s increasingly destructive wildfire season by nearly a month, according to new research. The study cannot confirm the shift is connected to climate change, but the results are consistent with climate models that predict drier autumns for California in a warming climate, according to the authors.
For years, Southern Nevadans have watched the water level in Lake Mead inch downward and wondered how long we could avoid the federally mandated rationing that kicks in when the lake elevation hits certain thresholds.
As drought conditions intensify across Colorado, at least 14 cities in the Denver metro area say they will join forces to warn residents of looming water shortages and the need to cut back use this spring. Denver Water’s Jason Finehout said a metro drought coordination effort would help ensure a consistent message on reducing water use in what is shaping up to be another alarmingly dry year.
Recent storms have boosted California’s vital Sierra Nevada snowpack but not enough to fully compensate for a dry start to winter and residents should use water wisely, a state official said Wednesday after the season’s latest measurements.
During Imperial Irrigation District Board meeting director comments, Norma Galindo commented from her remote distancing location, and started off memorializing recently passed, former IID General Manager, Kevin Kelley, then segued into a discourse about prayer.
“We talk about prayer, I don’t believe many do, or if they do, they pray for the wrong thing. I am troubled by the hypocrisy in our leadership when we talk about praying. We aren’t willing to talk with each other to resolve issues. It is a time to reflect, let bygones be bygones. I would hope Director Hamby would have the gumption to meet with me face to face to address issues. I know we can work together, and Director Hanks.”
Samuel Coleridge’s poem “The Rime of the Ancient Mariner” features the phrase, “Water, water, every where, nor any drop to drink.”
Unlike the Ancient Mariner who was trapped on a salt-water ocean without fresh water, we in Marin County have fresh water surrounded by a salty bay and ocean.
Your landscaping soil needs three things to feed the billions of microbes within it to transform brick-hard, lifeless dirt into healthy, living soil sponges: oxygen, water, and life. Think OWL to remember these important, interconnected factors.
Oxygen is needed by healthy plant roots and soil organisms. Healthy soil has lots of tiny little pockets of air. When soils are eroded, graded, or disturbed, their structure becomes compacted and hard. Compaction takes place when tiny air and water bubbles are squeezed out of the soil. This kills the healthy microbes working to keep your soil replenished. Microbes can be killed by fertilizers, pesticides, or even heavy traffic from people or vehicles.
Microbes and plans both need water to live. But too much water in your soil will displace oxygen, saturating the soil. This creates an anaerobic condition. It is the unhealthy microbes like bacteria, viruses, or parasites that prefer anaerobic soil. If this condition persists, diseases may develop. They will endanger the health of your garden.
Water is constantly moving through the soil. Water in the soil needs to be replenished as plants use it, as it evaporates from the soil surface, and as gravity pulls it down past the root zone of your plants.
The microbes consume organic matter, and then they are consumed by bigger creatures (worms, ants, slugs, centipedes, larvae, etc.). They are consumed in turn by creatures further up nature’s food chain. Photo: Malcolm Fowles, Wikipedia
Life in the soil includes all the bacteria, protozoa, nematodes, and fungi, the food they eat, the excretions they make, and the root systems they sustain. Living microbes are most quickly incorporated into your soil by adding high-quality compost.
Plants attract microbes to their roots by feeding them carbon. Bacteria and fungi hold the soil together with microscopic glues and binders. The microbes consume organic matter, and then they are consumed by bigger creatures (worms, ants, slugs, centipedes, larvae, etc.). They are consumed in turn by creatures further up nature’s food chain.
Carbon and other nutrients cycle through these many life forms, creating healthy living soil, no matter what the soil type.
Without any of these elements, your landscaping will not thrive. Organic matter, planning and some labor may be involved, but creating healthy soil using the OWL method – Oxygen, Water and Life – will pay off in reduced maintenance, reduced inputs, reduced pollution on land and in our waterways, and the beauty of your thriving, healthy landscape.

Precipitation is below average in California for the current water year. Despite recent storms that increased the statewide Sierra Nevada snowpack to 70% of average to date, the state is experiencing its second consecutive below average year for rain and snow. The water year starts on October 1 and ends September 30.
The Department of Water Resources Feb. 3 conducted the second manual snow survey of the season at Phillips Station. The manual survey recorded 63 inches of snow depth and a snow water equivalent, or SWE, of 17 inches, which is 93% of average for that location, according to the DWR. The SWE measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.
“The recent blast of winter weather was a welcome sight, but it was not enough to offset this winter’s dry start,” said DWR Director Karla Nemeth. “While there is still a chance we will see additional storms in the coming weeks, the Department and other state agencies are preparing for the potential for a second consecutive year of dry conditions.”
Below normal precipitation is favored throughout most of the southern tier of the United States in late February to early March, according to the National Weather Service Climate Prediction Center. La Niña conditions remain over the Pacific Ocean.
Statewide snow survey measurements reflect those dry conditions. Measurements from DWR’s electronic snow survey stations indicate that statewide the snowpack’s SWE is 12.5 inches, or 70% of the February 3 average, and 45% of the April 1 average. April 1 is typically when California’s snowpack is the deepest and has the highest SWE.
“The recent atmospheric storms have brought rain and snow to the northern Sierra Nevada, but conditions are still well below normal,” said Goldy Herbon, San Diego County Water Authority senior resources specialist.
Following last year’s below average water year, northern California is now experiencing its second straight water year of below average precipitation.

Another source of the state’s water supply, the Colorado River Basin, isn’t faring much better. The water year 2021 precipitation at the end of January for the Colorado River Basin is 66% of normal, according to the U.S. Bureau of Reclamation.
Precipitation totals to date are behind historical averages for two of the main sources of San Diego County’s supply, with two months to go in the winter season but, a couple of atmospheric rivers can change that quickly.
“The San Diego region will have a plentiful and reliable source of water due to actions taken by the Water Authority and its 24 member agencies to diversify the water supply,” said Herbon. “Continuing efforts to expand supply sources, including desalination, water reuse, and recycling, will ensure that the water needs are met for the region’s 3.3 million people and its $245 billion economy.”
Fall 2020 was extremely dry, especially in the Sierra Nevada, and follows last year’s below-average snow and precipitation, according to the DWR. With only a couple months remaining in California’s traditional wet season, DWR officials say Californians should look at ways to reduce water use at home.

Just as owners perform routine maintenance to keep their cars running smoothly, water systems need regular maintenance to provide reliable service. The Vallecitos Water District’s Valve Maintenance Program ensures these vital components in its water distribution remain in good working condition throughout the District.
To meet the promise of its day one executive order on Racial Equity and Support for Underserved Communities, the Biden administration needs to provide low-income communities, communities of color and Indigenous people the same access to clean and safe water that the rest of our nation takes for granted. Biden’s COVID-19 relief plan makes a down payment on that promise by funding improved access to clean water for the overburdened communities of Indian Country.
