Stretching along the eastern edge of the state, the Sierra Nevada region incorporates more than 25 percent of California’s land area and forms one of the world’s most diverse watersheds.
It features granite cliffs, lush forests and alpine meadows on the westside, and stark desert landscapes at the base of the eastside. Wildlife includes bighorn sheep, mule deer, black bear and mountain lions, hawks, eagles, and trout.
The majority of total annual precipitation – in the form of rain and snow – falls in the Sierra Nevada. Snowmelt from the Sierra provides water for irrigation for farms that produce half of the nation’s fruit, nuts and vegetables, and also is a vital source for dairies, which have made California the largest milk producer in the country.
In addition, Sierra snowmelt provides drinking water to Sierra Nevada residents and a portion of drinking water to 23 million people living in cities stretching from the Bay Area to Southern California.
The Rim fire in 2013 brought devastation to a vast swath of Sierra Nevada forests west of Yosemite National Park. But the third largest wildfire in state history also seemed to have worked a political miracle, at least for a while. In the aftermath of the blaze, environmental organizations, timber interests, state officials and the U.S. Forest Service buried decades of discord to forge an ambitious restoration and reforestation plan.
Sixty percent of California’s developed water supply originates high in the Sierra Nevada mountains. Our water supply is largely dependent on the health of our Sierra forests, which are suffering from ecosystem degradation, drought, wildfires and widespread tree mortality.
We headed into the foothills and the mountains to examine water issues that happen upstream but have dramatic impacts downstream and throughout the state.

With Floriston rates, or rate of flow on the Truckee River at Floriston, meeting the required mean flow of 500 cubic feet per second, and Lake Tahoe’s elevation below the maximum of 6,229.10 feet, the Lake Tahoe Dam remained closed until last week, which forced the two [rafting] companies off the water. Lake Tahoe’s elevation was measured at 6,228.95 on June 26, according to the Water Master’s daily report, with the flow rate at Farad measured at 591 cubic feet per second.
The largest privately-owned section of the Upper Truckee River is now in public hands, paving the way for another restoration project on an altered watershed harming Lake Tahoe’s famed clarity. This week the Tahoe Resource Conservation District announced the acquisition of Johnson Meadow, a 206-acre portion of a larger watershed that, in its original form, acted as a natural water filter for both the Upper Truckee River and Trout Creek.
Water supply for California’s cities and farms is largely dependent on snowmelt from the upper watershed in the Sierra Nevada. But that paradigm is being challenged by wildfires, climate change and widespread tree mortality.
Join us for a two-day tour as we head into the Sierra foothills and up into the mountains to examine water issues that happen upstream, but have dramatic impacts on water supply and quality downstream and throughout the state.
After two heavy winters following five years of drought, grass and brush are thick in the Tahoe Basin, putting local firefighting agencies on high alert for the fire season ahead. “We will see more intense fire because there is more fuel. That’s the message we’re getting from our fire behavior analysts and fuel specialists,” said Brice Bennett, spokesman for the California Department of Forestry and Fire Protection’s Amador/El Dorado Unit.
The way people play along Lake Tahoe’s 72 miles of shoreline could change this year. The latest iteration of theTahoe Shoreline Plan comes out Tuesday. The proposal would add 138 piers, of which 10 are public.
Lake Tahoe, the iconic high Sierra water body that straddles California and Nevada, has sat for more than 10,000 years at the heart of the Washoe tribe’s territory. In fact, the name Tahoe came from the tribal word dá’aw, meaning lake. The lake’s English name was the source of debate for about 100 years after it was first “discovered” in 1844 by people of European descent when Gen. John C. Fremont’s expedition made its way into the region.

Fremont’s expedition made its way into the region. Not long after, a man who carried mail on snowshoes from Placerville to Nevada City named it Lake Bigler in honor of John Bigler, who served as California’s third governor. But because Bigler was an ardent secessionist, the federal Interior Department during the Civil War introduced the name Tahoe in 1862. Meanwhile, California kept it as Lake Bigler and didn’t officially recognize the name as Lake Tahoe until 1945.
Sixty percent of California’s developed water supply originates high in the Sierra Nevada.Thus, the state’s water supply is largely dependent on the health of Sierra forests, which are suffering from ecosystem degradation, drought, wildfires and widespread tree mortality.

California voters may experience a sense of déjà vu this year when they are asked twice in the same year to consider water bonds — one in June, the other headed to the November ballot.
Both tackle a variety of water issues, from helping disadvantaged communities get clean drinking water to making flood management improvements. But they avoid more controversial proposals, such as new surface storage, and they propose to do some very different things to appeal to different constituencies.
It’s a recipe for flooding. A tropical storm pulling moisture from the South Pacific, often called an atmospheric river, will deliver mild temperatures and heavy rain to the snow-covered northern Sierra Nevada later this week.
The storms of March may not have rained glory on the state, but they dropped enough snow on the Sierra to greatly improve the drought situation and, with another storm rolling in this week, water resources officials believe thirsty California will make it through the year.
A series of supercharged storms that blasted the Sierra in March has bolstered the snowpack that was alarmingly low before the start of the month. … On Feb. 22, an average of 4.6 inches was measured and on March 23 an average of 15.5 inches was recorded, going from 16 percent to 56 percent of the April 1 average.
A series of storms have been a boon for California’s Sierra Nevada where nearly 16 feet of snow has piled up in March, more than double the paltry seasonal total before the month began.
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.
Frank Gehrke trudges through snow and ice, as he’s done for nearly four decades in the Sierra Nevada. He’s one of many state workers who takes monthly snow surveys, in the same spots, to figure out how much water is in the snowpack. And this old-fashioned way of measuring the snowpack is quite laborsome.
California water officials tromped through long-awaited fresh snowdrifts in the Sierra Nevada mountains Monday, but a welcome late-winter storm still left the state with less than half the usual snow for this late point in the state’s important rain and snow season.
The storm that wrought avalanches at ski resorts and whiteouts on mountain roads last week was so fierce that California water officials postponed their much-anticipated monthly survey of snow depth, setting the stage for potentially better news this week.
Last week’s major snowstorms brought a welcome change to the Sierra Nevada Range — the source of nearly one-third of California’s water — boosting the overall snowpack by nearly 80 percent. But despite the blizzards dumping 5 to 8 feet of fresh snow, the overall snowpack remains well below normal.
Welcome drifts of fresh snow await California’s water managers on their late-winter survey of the vital Sierra Nevada snowpack Monday after a massive winter storm slowed the state’s plunge back into drought. The storm piled snow by the foot in the mountains, forcing Department of Water Resources officials to postpone the measurement for a few days.
Despite last week’s heavy snowfall, Tahoe ski resorts know they can’t predict how strong each winter will be. They suffered through drought years earlier this decade.
A major storm system is forecast to slam into California from Alaska and Canada starting Wednesday night, bringing soaking rain to the Bay Area on Thursday and dumping up to seven feet of new snow to the historically dry Sierra Nevada by Saturday. But as welcome as the snow is during a very dry winter so far, it won’t be enough to return the Sierra Nevada — the source of 30 percent of California’s water supply — back to its average for the year, experts said Tuesday.
A winter storm is expected to drop several inches of new snow Thursday in the Sierra Nevada, and meteorologists with the National Weather Service are optimistic more systems will follow in the coming days. Thursday’s storm, which could deliver 6 to 10 inches of snow in the higher elevations, comes on the heels of a system Monday that brought as much as 7 inches of fresh powder to Tahoe area ski resorts.
In the Sierra Nevada, snowpack levels are running below even the darkest days of the drought, with cross-country ski resorts closed and mountain biking becoming the sport of choice until the snow returns. … February is historically a wet month, but not this year.
Every day, people flock to Daniel Swain’s social media platforms to find out the latest news and insight about California’s notoriously unpredictable weather. Swain, a climate scientist at the Institute of the Environment and Sustainability at UCLA, famously coined the term “Ridiculously Resilient Ridge” in December 2013 to describe the large, formidable high-pressure mass that was parked over the West Coast during winter and diverted storms away from California, intensifying the drought.
Swain’s research focuses on atmospheric processes that cause droughts and floods, along with the changing character of extreme weather events in a warming world. A lifelong Californian and alumnus of University of California, Davis, and Stanford University, Swain is best known for the widely read Weather West blog, which provides unique perspectives on weather and climate in California and the western United States. In a recent interview with Western Water, he talked about the Ridiculously Resilient Ridge, its potential long-term impact on California weather, and what may lie ahead for the state’s water supply.
As relentless sunshine continued to pound California on Thursday, the Sierra Nevada hit a reckoning point: There’s less snowpack now than on the same date three years ago, when the winter went down as the driest in recorded history and sent shudders through cities, farmlands and the state Capitol.
The T-shirt-wearing temperatures and lack of winter rain have combined to push nearly half of California into all-too-familiar territory: a state of drought. … At Phillips Station south of Lake Tahoe, where state water officials base their monthly snow surveys, hydrologists on Thursday found just 13 percent of average snowpack.
Amid record-setting heat in the state’s south, California’s water managers will measure the Sierra Nevada snowpack, which supplies water to millions. Department of Water Resources officials will trek to the mountains Thursday to check the snow depth, one gauge of the state’s water supply.
Up to another foot of snow is possible in the mountains around Lake Tahoe on the heels of a storm packing 100 mph (160 kph) winds that triggered power outages in Reno. The storm left as much as 16 inches (40 centimeters) of new snow at Sierra ski resorts, the National Weather Service said Thursday.
This is going to be a big year for one of the state’s smallest agencies. As California redoubles its efforts to reduce greenhouse gases, officials are rooting around for new ways to meet the state’s goals. Included in their plan: recruiting billions of redwood, oak and pine trees to help diminish planet-warming gases by pulling carbon dioxide from the atmosphere.
Farmers, ecologists, water managers, even those tasked with fighting backcountry wildfires could greatly benefit from knowing months in advance how much water will be available from melting mountain snow every spring. For decades predicting snowpack accumulation has been largely unreliable, based solely on historical data and capricious El Nino weather patterns.
There’s a term for what’s going on right now in the Sierra Nevada and the mountains that feed the Colorado River. It’s called a “snow drought,” and Nevada climate scientists warn that Westerners had better get used to the phenomenon.
A winter storm system is heading to California, and is expected to bring the first significant snow to the northern Sierra Nevada since November, but spare Southern California the threat of mudslides.
California skiers and riders are facing the best conditions of the season after recent storms dumped snow from Lake Tahoe to Mammoth Lakes, frosting slopes ahead of the long Martin Luther King holiday weekend.
The grassy brown Sierra meadow where California’s water managers gave the results of the winter’s first manual snowpack measurements Wednesday told the story — the drought-prone state is off to another unusually dry start in its vital winter rain and snow season. “We would like to have had more snow,” Grant Davis, head of California’s Department of Water Resources, told news crews gathered in this mountain field, bare of all but a few crusty dots of old snow.
It’s been almost a year since Los Angeles residents felt any real rain, and precious little snow is in the Sierras, but water managers say it’s too early for fears that California is sliding back into drought as abruptly as the state fell out of it. Water officials carry out the first of their regular ritual winter snow measurements before news cameras on Wednesday.
California’s already towering Sierra Nevada summits rose to new heights during the drought, albeit by just a hair. A study by NASA scientists published Wednesday found that the granite peaks of the 400-mile range were pushed nearly an inch upward between 2011 and 2015, a phenomenon linked not only to known tectonic forces but the expansion of the land as it dried out and shed water weight.
The Sierra Nevada mountains grew nearly an inch taller during the recent drought and shrank by half an inch when water and snow returned to the area, according to new research from NASA’s Jet Propulsion Laboratory in La Cañada Flintridge. Researchers used 1,300 GPS stations throughout the mountain range to closely observe how its elevation changed during the drought.
California’s forests are seeing a continued die-off of trees even a year after last year’s heavy rains ended the state’s crippling drought. The U.S. Forest Service announced Monday that 27 million trees died over the past 13 months after five dry years left them severely dehydrated and vulnerable to bark beetle attack.
For years, Sierra residents have murmured about winter rain falling on trails that used to be covered in snow, but there has been no scientific evidence to back up a change in the snowfall pattern. Now, a new piece of research suggests the snow line, the point of elevation above which rain turns to snow during winter storms, may be changing.
Tahoe Resource Conservation District is three years into a long-term aquatic invasive species eradication project on the Truckee River — and the progress is encouraging. TRCD is working to eliminate Eurasian watermilfoil from a 3-mile stretch of the Truckee River, starting above the Tahoe City dam and continuing down to Alpine Meadows Road.

It’s only Halloween, but winter is on the way. Two storm systems moving out of the Gulf of Alaska are on track to bring the first substantial snow of the 2017-18 winter season to the Sierra Nevada, starting Friday, and widespread rainfall across the Bay Area over the weekend.
Mountain meadows are starting to get some respect. For over a century, meadows were the first alpine environments targeted for development, grazing and farming, because they tend to be flat and packed with rich soil and nutritious plants. But we’re starting to understand that meadows have a much more important role to play for society at large. Meadows, it turns out, are water banks.

One of north Lake Tahoe’s cutest residents, the American pika, has disappeared. UC Santa Cruz researchers have discovered an extinction spanning from Tahoe City to Truckee, the largest pika die-off in the modern era.
Endangered California frogs are getting an immunity boost from scientists who are scooping them up from remote Sierra Nevada ponds and sending them to big city zoos for inoculation, giving them a fighting chance to beat extinction, officials said Wednesday.
Federal officials promised Tuesday to protect Lake Tahoe for future generations, a pledge that one said doesn’t rule out also maintaining a robust regional economy.
Intense seasonal changes in 2016 — hallmarks of climate change — killed huge swaths of forest around the lake and nourished invasive species, according to the annual Tahoe State of the Lake Report released Thursday by the UC Davis Tahoe Environmental Research Center.
Lake Tahoe’s famously clear waters continue to warm, and the surrounding forests face dire threats due to drought, disease and insects, according to the annual Tahoe State of the Lake report by researchers at UC Davis. The second deepest lake in the United States after Crater Lake, Lake Tahoe has warmed by half a degree Fahrenheit each year for the past four years — 14 times faster than the historic rate, the report said.
Tahoe is brimming, nearly full for the first time in 11 years, and stunningly beautiful in all its blue-water glory. … When the first heat wave of the season hit in mid-June, more than 12 billion gallons of water flowed into the lake in a single week.
The population at Lake Tahoe swells by up to five times its year-round population on busy summer weekends. The influx of tourists taxes an infrastructure designed for fewer people.
Trails, roads and campgrounds throughout the Sierra high country were hit hard by snow and runoff from one of the largest snowpacks in recorded history, leaving public agencies scrambling and summer visitors feeling lost.
Visitors to North Lake Tahoe this summer will notice the steady flow of the Truckee River, the high water level of Lake Tahoe, and dense green growth that has sprung up across the region thanks to record snow and rainfall this winter. But they’ll also see an increasing number of dead trees.
The barrage of storms that pounded the Sierra Nevada this winter and spring added up to a snowpack that’s massive. Amid a major heat wave all of that snow is now melting — and fast. How fast?
Sixty percent of California’s developed water supply originates high in the Sierra Nevada. Thus, the state’s water supply is largely dependent on the health of Sierra forests, which are suffering from ecosystem degradation, drought, wildfires and widespread tree mortality.

In singing about the Kern River, Merle Haggard put it best: “It’s a mean piece of water, my friend.” As a heat wave tightens its grip on California, the water in the massive Sierra Nevada snowpack is being squeezed into the state’s rivers and reservoirs, creating dangerous conditions downstream.
Sleds and skis in June? A rare winter-like storm brought more snow to the Sierra Nevada on Monday, giving skiers the opportunity to enjoy the slopes as summer gets underway.
Every year for almost half a century, California snow surveyor Pat Armstrong has trekked the rugged Sierra Nevada with three simple tools: a snow core tube, a scale and a notebook. For as long as he can remember, state water officials have relied on the accuracy of those tools to deliver crucial data on the size of the Sierra snowpack and its ability to sustain a growing population.
People came here for the forest, to live among 200-foot-tall pine trees that shaded their mountain cabins and scented the air. But in the span of two short years, tens of thousands of those trees are gone, ravaged by bark beetles until their green needles turned orange.
To say backpackers and hikers will encounter more snow than they’re used to is to drastically understate the problem. The snowpack throughout the Sierra rivals, and in places exceeds, records set during the massive winter of 1982-83. “We are in rare territory here with the winter we’ve had,” said Chris Smallcomb, a meteorologist with the National Weather Service in Reno.
As of Tuesday afternoon, lake level was at 6,228.18 feet, just .92 inches from Lake Tahoe’s legal limit of 6,229.1 feet. The Upper Truckee River was just shy of 8 ½ feet — about 2 feet from flood stage.
Climate change is causing Lake Tahoe to warm sooner in the spring than it has historically, disrupting the normal mixing of shallow and deep water and undercutting gains made in reversing the loss of clarity of the cobalt mountain lake, scientists say.
With snowpack 200 to 300 percent of normal, the Tahoe area fire season will likely be delayed this year. Grass is the primary fuel for wildfires. It probably won’t be drying out until July and August.
The deaths of five people in two Tulare County rivers in less than a month are prompting officials to warn the public about the dangers of rushing water fed by the heavy snowpack now melting in the Sierra. “Stay away from the river’s edge, and don’t enter the water,” said Tulare County Sheriff Mike Boudreaux.
The Stanislaus River charged at well above its typical May volume as Lucas Huffman launched his kayak Tuesday at Knights Ferry. … The central part of the [Sierra Nevada] range has had near-record rain and snow. Temperatures have spiked past 90 degrees, and the snowmelt has sped up.
State officials on Monday reported a near-record May snowpack, but the bountiful winter that demolished California’s five-year drought is now increasing the risk of late spring flooding, as temperatures climb across the Sierra Nevada.
Water experts say the heavy spring runoff will likely continue until summer, testing California’s flood management efforts in what is a delicate balance between keeping enough water behind dams to prevent downstream surges and releasing enough to make space for the incoming melt.
A series of late-season storms has vaulted this winter into the history books, making it the wettest winter for California’s northern Sierra Nevada in nearly a century of record-keeping, according to the California Department of Water Resources.
Not only will this week’s incoming storms be packing their usual grab bags of mischief for Northern California – widespread and heavier precipitation, winds gusting up to 30 mph, snowfalls dropping from 5,000 to 3,500 feet – but the systems appear to have their hearts set on breaking one big thing: The all-time wettest water year on record for the Northern Sierra, the most important source of water for the entire state.
As big snowflakes fell high in California’s Sierra Nevada on Thursday, surveyors on snowshoes measured the deepest springtime snowpack in years and said it boosted concerns about destructive floods when all that snow melts.
The biggest blizzards are over. But as state water officials head into the Sierra Nevada on Thursday for the annual April 1 snowpack reading — the most important of the year for planning summer water supplies — California still has a huge amount of snow covering its highest mountain peaks, an avalanche that has buried the state’s punishing drought.
The muddy ski slopes of 2015 paired with the powder-covered ones of 2017 show the astonishing difference between a year when snow levels were drastically low and this season when unrelenting storms slamming the northern Sierra Nevada are burying the ski lifts on a weekly basis.
The depressing scene of boat docks sitting high and dry on wide beaches around Lake Tahoe will likely be a fleeting memory this summer. Winter’s unrelenting storms built up a substantial Sierra snowpack and are expected to fill the lake for the first time in 11 years.
Plunging the long, metal rod into the snow beneath his feet in the mountain town of Phillips, state snow survey chief Frank Gehrke measured the Sierra Nevada snowpack Wednesday not against California’s recent, historic drought but against its biggest rain years.
The massive snowdrifts in the Sierra Nevada could finally bring the California drought to its knees and keep skiers on the slopes long enough to celebrate the Fourth of July.
As the rain and snow have fallen this winter, so have California’s hillsides, forcing the closure of major roads through the Sierra Nevada and causing millions of dollars in damage.
Top scientists announced in January that last year was the hottest year on record — an announcement they’ve made three years in a row, with 2014, 2015 and now 2016 each being declared warmer than the previous year.
Clambering through a snowy meadow with drifts up to the tree branches, California’s water managers measured the state’s vital Sierra Nevada snowpack Thursday at a drought-busting and welcome 173 percent of average.
Roaring storms that brought California almost a year’s worth of snow and rain in a single month should make state water managers’ Sierra snowpack survey Thursday a celebration, marking this winter’s dramatic retreat of the state’s more than 5-year-drought, water experts say.
On Thursday, officials with the state Department of Water Resources are scheduled to escort reporters up to a Phillips Station, a meadow off Highway 50 near Lake Tahoe, for the monthly manual snowpack reading.
The ponderosa pine had taken root decades before the Revolutionary War, making a stately stand on this western Sierra Nevada slope for some 300 years, Nate Stephenson figures. Then came the beetle blitzkrieg.
Tahoe-area ski resorts should have a banner holiday weekend – if they can dig out from the back-to-back storms that have delivered more snow than they’ve seen in years.
The first manual survey this year of California’s snowpack revealed Tuesday that it holds about half as much water as normal, casting a shadow on the state that’s hoping to dodge a sixth straight year of drought, officials said.
Around the start of each year, California water officials make a big show out of measuring the Sierra Nevada snowpack for reporters. Tuesday’s measurement before a throng of cameras was fairly bleak: Water content in the snowpack stood at just 53 percent of average, about a third as much water as the same time last year at that site.
Surveyors will plunge poles into the Sierra Nevada snowpack near Lake Tahoe on Tuesday, taking the season’s first measurement by hand of the snow’s water content as California flirts with a sixth year of drought.
ARkStorm stands for an atmospheric river (“AR”) that carries precipitation levels expected to occur once every 1,000 years (“k”). The concept was presented in a 2011 report by the U.S. Geological Survey (USGS) intended to elevate the visibility of the very real threats to human life, property and ecosystems posed by extreme storms on the West Coast.
The Sierra Nevada is getting soaked this year, and Lake Tahoe is one of the biggest beneficiaries. The sixth-largest lake in the United States, which straddles California and Nevada, reached its natural rim after weekend storms dumped 12.5 billion gallons of water into the lake.
Nearly a foot and a half of snow fell at high-elevation areas across the Truckee-Tahoe region this weekend, and with more snow in the forecast, it’s shaping up to be a white Thanksgiving.
An environmental review of a development plan for the Lake Tahoe region adequately addressed concerns about the lake’s water quality, a federal appeals court ruled Wednesday.
In the 1950s, California wildlife authorities used to fly over remote lakes and creeks in Yosemite National Park and deliver precious cargo: hatchery-raised trout. The policy was great for fishing enthusiasts.
Several environmental groups returned to their natural habitat in the courthouse on Wednesday in hopes of securing Endangered Species Act protections for the Pacific fisher, a mink-like creature found partly in California’s southern Sierra Nevada mountains.
Snow fell Monday in the Sierra Nevada’s higher elevations, where a weekend storm dumped several inches of fresh snow overnight. Snow was also reported Monday at Lassen Volcanic National Park and on Mt. Shasta.
Four years into the drought, bark beetles did what was expected of them in the conifer woods of Tuolumne County. They bored into the trunks of moisture-stressed pines, cutting off the trees’ nutrient flow.
When naturalist John Muir explored Lyell Glacier in Yosemite National Park about 150 years ago, the river of ice stretched as far as 10 football fields between the peaks of the Lyell Canyon, a glacier one might expect to see in Alaska, not California.
A native California frog once on the brink of extinction is making an encouraging comeback in Yosemite National Park, raising hopes for amphibians like it worldwide that are dying off at an alarming rate, researchers said Monday.
President Barack Obama, fixed against a pristine backdrop of the Sierra Nevada, issued a forceful defense Wednesday of his administration’s policies to address climate change, warning that rising temperatures could lay waste to decades of conservation efforts at Lake Tahoe and throughout the United States.
Standing beneath the forest-green peaks of the Sierra Nevada, President Barack Obama drew a connection Wednesday between conservation efforts and stopping global warming, describing the two environmental challenges as inseparably linked.
The White House on Wednesday announced a series of new funding and environmental programs to address the deteriorating health of Lake Tahoe and the surrounding forests caused in part by the increasing temperatures brought about by climate change.
At a conservation summit on the southern shore of Lake Tahoe, President Obama on Wednesday pointed to the environmental degradation of the lake’s once-crystal-clear waters as proof of the damage caused by climate change and warned of the threat posed by Republican leaders who continue to deny its existence.
Owens Lake is a dry lake at the terminus of the Owens River just west of Death Valley and on the eastern side of the Sierra Nevada. For at least 800,000 years, the lake had a continuous flow of water, until 1913 when the Los Angeles Department of Water and Power (LADWP) completed the 233-mile Los Angeles Aqueduct to supplement the budding metropolis’ increasing water demands.

The Fish and Wildlife Service has stuck to its guns and is designating 1.8 million acres of mostly public California land as habitat critical for the preservation of the Yosemite toad and two frog species peculiar to the Sierra Nevada mountains.
Two types of yellow-legged frogs, and a kind of toad found in Yosemite National Park, won extra protection Thursday when federal authorities declared nearly 3,000 square miles in California’s Sierra Nevada mountains as critical habitat for the endangered animals.
The leaves atop giant sequoias in the Sierra Nevada are better at storing water than those closer to the ground, an adaptation that may explain how their treetops are able to survive 300 feet in the air, researchers at American River College and Humboldt State University have found.
Another Memorial Day came and went this year, but the marina at Meeks Bay Resort didn’t open for a third straight season — this time due to a high concentration of pollutants, an issue that apparently has been a concern for more than a decade.
It has been a scene playing out daily in the Sierra this spring and now summer: Cal Fire firefighters cutting down trees and thinning out parts of the forest in the wake of an unprecedented crisis, the deaths of 66 million California trees, said Edwin Simpson, a forester with Cal Fire.
A growing network of online cameras installed on forested mountaintops is changing the way crews fight fires by allowing early detection that triggers quicker, cheaper and more tactical suppression.
The number of trees in California’s Sierra Nevada forests killed by drought, a bark beetle epidemic and warmer temperatures has dramatically increased since last year, raising fears they will fuel catastrophic wildfires and endanger people’s lives, officials said Wednesday.
The California drought is carving an unprecedented path of ruin through Sierra forests, killing trees by the millions and setting the stage for a potentially devastating wildfire season that’s already burning homes and closing freeways in the southern half of the state.
A lethal combination of drought, heat and voracious bark beetles has killed 26 million trees in the Sierra Nevada over the last eight months — an alarming finding for a state already raging with wildfires fueled by denuded landscapes and desiccated tinder.
California’s drought and a bark beetle epidemic have caused the largest die-off of Sierra Nevada forests in modern history, raising fears that trees could come crashing down on people or fuel deadly wildfires that could wipe out mountain communities.
A type of frog made famous by Mark Twain will soon be hopping and swimming through California’s Yosemite National Park after a decades-long absence, officials said Wednesday. … This is the latest effort to restore native animals to Yosemite.
In another sign of the warming climate, key species of trees in California’s Sierra Nevada mountain range — including lodge pole pine, red fir and western white pine — are shifting to higher elevations in search of cooler temperatures, a broad new study by state biologists has found.
Nevada’s wildland firefighters are readying themselves for a treacherous fire season in months ahead. That’s because a multi-year drought interrupted by El Nino moisture created conditions that cranked up the risk of wildfire in both the Sierra Nevada and Great Basin.
California’s “frozen reservoir” is melting fast. Unusually high temperatures this spring have acted like a blow-drier on accumulated winter snows, despite a healthy boost during the stormy month of March.
Trees in California are dying at the highest rate in at least 15 years, raising the risk of faster-moving and more-intense forest fires, according to the U.S. Forest Service.
Twenty-eight million. That’s the estimated number of trees in California that were dead or dying in 2015 as a result of the ongoing drought, according to the U.S. Department of Agriculture.
When the Tahoe Keys were created in the 1960s they became Lake Tahoe’s largest commercial marina. … It’s possible that no one could have foreseen that those warm, shallow channels would one day be home to Tahoe’s most dense population of invasive species.
