Photographs of Yosemite's iconic Half Dome peak have revealed the astonishing extent of California's historic drought. The images, which show the peak in the third week of March each year between 2011 and 2015, reveal how swiftly snowfall has depleted year to year. The snow is typically at its deepest in the area in late March and, as seen in the 2011 photograph, it previously covered peaks including the Half Dome. But this year, the fourth consecutive year of drought in California, the 9,000-foot peak doesn't bear a single flake of snow. Earlier this month, officials reported that the Sierra Nevada snowpack, which gives an indication of upcoming water supply, is just five per cent of its normal depth - and barely above the record low set in 1991. The lack of water comes after the winter of 2014 was the hottest on record for California. Scroll down for video. Hidden: A photo taken by a Yosemite Conservancy webcam on March 19, 2011 shows Yosemite's Half Dome peak covered with snow. Depleting: The following year, in March 2012, the iconic peak is similarly covered in deep snow. In response, state regulators voted earlier this month to impose a new set of water conservation rules, such as bans on watering yards and stopping restaurants serving customers water unless they specifically ask for it. Farmers have said they expected to leave as much as a million acres unplanted, nearly twice the amount of last year, the New York Times reported. 'It looks like we are on our way to the worst snowpack in history,' state climatologists Michael Anderson told the Times. 'Unless we end up with some particularly good snows here in March, we are going to end up with a new lowest rank here.' But the Half Dome peak is likely to stay clear of snow because there are no major snowstorms forecast for the rest of the month. Earlier this month, the United States Department of Agriculture noted that as well as California, droughts are ravaging Nevada and Utah and also parts of Arizona, New Mexico, Colorado, Washington and Oregon. The photographs were taken by the Yosemite webcam provided by Yosemite Conservancy, which is funded by donations. While all years show the peak on March 19, the 2014 image shows it on March 17 as a March 19 photograph was not available. Warming temperatures: But by March 2013, the peak is drastically different - with far less snow as temperatures stay higher. Depleting: The following year, 2014, also shows far less snow than in previous years as drought ravages states on the West Coast. Dry: By March this year, the fourth consecutive year of drought in California, the peak barely shows a flake of snow.

Fotografier av Yosemites ikoniska halvdometopp har avslöjat den häpnadsväckande omfattningen av Kaliforniens historiska torka. Bilderna, som visar toppen under den tredje veckan i mars varje år mellan 2011 och 2015, visar hur snabbt snön har tömts år efter år. Snön är typiskt som djupast i området i slutet av mars och, som framgår av 2011 års fotografi, den tidigare täckta toppar inklusive Half Dome. Men i år, det fjärde året i rad av torka i Kalifornien, bär toppen på 9 000 meter inte ett enda snöflagor. Tidigare denna månad rapporterade tjänstemän att Sierra Nevadas snösäck, som ger en indikation på kommande vattenförsörjning, bara är fem procent av dess normala djup - och knappt över rekordlågt satt 1991. Bristen på vatten kommer efter vintern 2014 var det hetaste på rekord för Kalifornien. Scrolla ner för video. Dold: Ett foto taget av en Yosemite Conservancy webbkamera den 19 mars 2011 visar Yosemites halvdometopp täckt av snö. Utarmning: Följande år, i mars 2012, är den ikoniska toppen på liknande sätt täckt av djup snö. Som svar, statliga tillsynsmyndigheter röstade tidigare denna månad för att införa en ny uppsättning regler för vattenvård, såsom förbud mot vattning gårdar och stoppa restauranger som betjänar kunder vatten om de inte särskilt ber om det. Jordbrukare har sagt att de förväntade sig att lämna så mycket som en miljon hektar oplanterade, nästan dubbelt så mycket som förra året, rapporterade New York Times. "Det ser ut som om vi är på väg till den värsta snöpacken i historien," delstatliga klimatologer Michael Anderson berättade Times. "Om vi inte får några särskilt bra snö här i mars, kommer vi att sluta med en ny lägsta rang här. " Men Half Dome-toppen håller sig sannolikt undan snö eftersom det inte finns några större snöstormar som prognostiseras för resten av månaden. Tidigare denna månad konstaterade USA:s jordbruksdepartement att torkan, förutom Kalifornien, härjar i Nevada och Utah och även i delar av Arizona, New Mexico, Colorado, Washington och Oregon. Fotografierna togs av Yosemite webcam som tillhandahölls av Yosemite Conservancy, som finansieras genom donationer. Medan alla år visar toppen den 19 mars 2014 bilden visar den den 17 mars som en 19 mars fotografi var inte tillgänglig. Värmande temperaturer: Men i mars 2013 är toppen drastiskt annorlunda - med betydligt mindre snö då temperaturen förblir högre. Utarmning: Året därpå, 2014, visar också betydligt mindre snö än tidigare år då torkan härjar stater på västkusten. Torr: I mars i år, det fjärde året i rad av torka i Kalifornien, visar toppen knappt en flagn av snö.
Photographs of Yosemite's iconic half-dome race have revealed the astounding extent of California's historic drought. The images, showing the peak during the third week of March each year between 2011 and 2015, show how quickly the snow has been emptied year after year. The snow is typically at its deepest in the area at the end of March and, as evidenced by the 2011 photograph, the previously covered peaks including Half Dome. But this year, the fourth year in a row of droughts in California, bears the top of 9,000 feet (9,000 m) not a single snowflakes. Earlier this month, officials reported that the Sierra Nevada snowbag, which gives an indication of upcoming water supply, is only five percent of its normal depth - and barely above record low set in 1991. The lack of water comes after winter 2014 was the hottest on record for California. Scroll down for video. Hidden: A photo taken of a Yosemite Conservancy webcam on 19 March 2011 shows Yosemite's half-dome top covered in snow. Impoverishment: The following year, in March 2012, the iconic peak is similarly covered in deep snow. In response, state regulators voted earlier this month to introduce a new set of rules for water management, such as prohibition of watering farms and stopping restaurants serving customers water unless they specifically ask for it. Farmers have said that they expected to leave as much as a million acres unplanted, almost twice as much as last year, the New York Times reported.

But the Half Dome peak is likely to stay away from snow because there are no major blizzards forecasted for the rest of the month.

While all the years show the peak on March 19, 2014 the picture shows it on March 17 as a March 19 photograph was not available. Warming temperatures: But in March 2013 the top is drastically different - with significantly less snow as the temperature remains higher. Deterioration: The following year, 2014, also shows significantly less snow than in previous years when drought ravages states on the west coast. Dry: In March of this year, the fourth consecutive year of drought in California, the top shows barely a flake of snow.
