The Federal Emergency Management Agency, the federal government’s first responder to floods, hurricanes and other natural disasters, has eliminated references to climate change from its strategic planning document for the next four years.
State Parks workers were pulling cable up a launch ramp at Bidwell Marina Thursday because the water level in Lake Oroville is on the rise. March’s storms have brought the lake level up almost 13 feet since the start of the month, according to the Department of Water Resources website.
Every storm helps improve the state’s summer water picture, scientists and state water planners said Thursday. But even taking into account this storm and a big one two weeks ago, the Sierra Nevada snow pack — the source of nearly one-third of California’s water supply — still is only about half of normal for this winter season, with this month’s totals measuring just half of the 1991 miracle month’s final tally.
Atmospheric rivers are vital to western water supplies, yet until very recently they were poorly understood: difficult to predict and measure, and very hard for scientists to estimate where they would make landfall. … Now a new study by scientists at Colorado State University in Fort Collins has revealed a way to predict atmospheric river storms as much as five weeks in advance.
The State Water Resources Control Board’s proposal to impose permanent conservation rules – such as prohibiting hosing down driveways, watering lawns less than two days after it rains and washing a car without attaching a shut-off nozzle to the hose – ran into a cascade of opposition.
Local tribes’ say critically important dam water releases meant to protect threatened salmon on the Klamath River from deadly parasitic disease outbreaks are being contested by irrigators and water districts in the Klamath Basin as they face drought conditions.
According to the National Water and Climate Center’s forecast for the Rio Grande Basin, the water supply outlook for spring and summer remains “dire.” … And conditions on the Colorado River, which feeds Lake Mead, don’t look good this year. The March forecast for the Colorado River Basin remains “well below average.”
Federally endangered coho salmon and threatened steelhead trout respond to the rains, which create runoff and are a natural invitation for the fish to begin swimming from the oceans upstream into creeks to spawn in the Lagunitas Creek watershed. In December — a key month for coho migration — just .31 of an inch of rain fell in the county as measured by the Marin Municipal Water District.
Well into the first of two winter storm warnings, some Lake Tahoe ski resorts are reporting more than 1 foot of fresh snow. … Another winter storm warning will take effect at 5 p.m. Thursday and last until 5 a.m. Saturday.
Columbus Tustin Middle School students spent the first part of their school year studying climate change. So they knew a bit about what they were saying when they hosted a climate change summit March 8 on campus.
Water is a valuable resource that affects nearly all aspects of life on earth. It also is limited, so people use a variety of methods to ensure that supply meets demand. One such technique is cloud seeding – adding particles to the atmosphere to promote formation of rain or snow.
The Trump administration is pushing forward with a colossal public works project in Northern California — heightening the towering Shasta Dam the equivalent of nearly two stories. The problem is that California is dead-set against the plan, and state law prohibits the 602-foot New Deal-era structure from getting any taller.
California’s 2012-2016 drought revealed vulnerabilities for water users throughout the state, and the long-term record suggests more challenges may lie ahead. An April 19 workshop in San Pedro will highlight new information about drought durations in Southern California watersheds dating back centuries. Registration is now open for the Paleo Drought Workshop, Using the Past to Improve Drought Preparedness Now.
A pair of storms moving across the Bay Area this week and into the Sierra Nevada could dump eight feet of snow at higher elevations, said Mike Kochasic, meteorologist at the National Weather Service in Sacramento. And although rain and snow are expected to remain far below average for the season after a bone-dry January and February, it’s still a relief to everyone from skiers to the state’s drought monitors.
Rain hit the Bay Area hard early Tuesday morning, and little is expected to change for most of the week. “A cold front is moving across the region this morning,” said Roger Gass of the National Weather Service in Monterey
Those severe winter storms that have been plaguing the East Coast might be linked to a rapidly warming Arctic, according to a new study on Arctic temperatures and extreme weather in a dozen U.S. cities. While the findings published in the journal Nature Communications build on earlier studies that have looked into this connection, they drew criticism from other researchers who questioned some aspects of the work.
