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 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.
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.
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.

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.

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.
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. Join us as we head up into the foothills and the mountains to examine water issues that happen upstream but have dramatic impacts downstream and throughout the state.
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.
