Oct. 1 is the beginning of what hydrologists call the “water year.”
Historically, California’s reservoirs are near their lowest levels by this point after months of being drawn down, mostly to irrigate fields and orchards, during the state’s precipitation-free summer.
October 1 marked the beginning of the new Water Year in California. Water years here run from October 1 until September 30 of the next calendar year, and are named for the calendar year of the bulk of the water year (January-October). It is a good time to reflect on the last year and make largely futile predictions of precipitation for the coming 12 months.
October isn’t just the start of our spooky season — it’s also the official start of the new water year. Historically, our wet season has stretched from mid-October to April, and water managers across the state are gearing up for what could be an even wetter year than last year, given the El Niño climate pattern, and a changing water cycle driven by human-caused climate change.
Water leaders across California are beginning to prepare for another wet winter, as a new water year got underway this week.
According to the U.S. Bureau of Reclamation, the state’s reservoirs are the fullest they’ve been at the start of a water year in 40 years. And, with an El Niño weather pattern looking more and more likely, so is the possibility for a lot of rain in the months ahead.
A new water year is here and there is much anticipation for what a growing El Niño will bring California. There is a likelihood the state could see back to back big water years.
After a year of unprecedented heat and flooding, experts are cautiously hopeful for California’s new water year with the threat of the historically unruly El Niño looming.
With the start of the new water year this week, state officials say there is plenty to celebrate. State climatologist Michael Anderson said in a Tuesday briefing that between October 2022 to March of this year, the state got 153% of normal rainfall, making it the sixth wettest water year on record.
The San Diego County Water Authority has the reliable water supplies to meet the region’s needs for 2024, owing in part to more efficient water use and a supply diversification strategy, it was announced on Oct. 2.
The water year began Sunday, Oct. 1, which hydrologists used to begin measuring the snow and rain that will help carry users through dry summer months the following calendar year.
Thanks to a decades-long supply diversification strategy and continued efficient use of water across the region, the San Diego County Water Authority announced today that the region has reliable supplies to meet demands in Water Year 2024, which started Oct. 1.
Hydrologists use Oct. 1 to begin measuring the snow and rain that will help carry water users through dry summer months the following calendar year. This fall, El Niño conditions continue to strengthen and could bring above-average precipitation to Southern California.
From the backcountry of Campo to the back roads of Ramona, firefighters were ready to roll last fall at even the hint of wildfire.
Two years of below-average rain and high temperatures had left the landscape parched. Something as small as heat from a car muffler could be enough to ignite grass. Firefighters described the region as primed to burn.
Sept. 30 marks the end of a water year to remember in California.
With the new water year kicking off Oct. 1, it’s worth looking back at the water year that was from record snowfall to landfalling tropical storms and everything in between.
