WATER: Snowpack dismal in Sierras, Mendocino National Forest
NORTHERN CALIFORNIA – The snowpack in the Sierras and in parts of the Mendocino National Forest has dwindled to the point of being nearly nonexistent or gone altogether, and the lack of snow caused state officials to cancel the latest public snow survey.
The Department of Water Resources was set to hold the snow survey event on Friday, but said that, due to the prospect of just finding bare ground at Phillips Station in the Sierra Nevada, 90 miles east of Sacramento, there was no point in going forward.
“This is the first time we formally canceled the media component of the snow survey. There is no need, since there is nothing to see, but bare ground, however reading are still taken by visual indicators and electronically at the survey locations,” Jennifer Iida, a public information officer with the Department of Water Resources, told Lake County News.
Bare ground was just what was found at last month's snow survey, as Lake County News has reported.
When Gov. Jerry Brown attended the April 1 survey at Phillips and announced a mandatory 25-percent reduction in water use across the state, the ground was barren of snow in every direction.
State officials said it was the only April 1 since the Department of Water Resources began surveying Phillips in 1941 that no snow was found there.
“We can’t count on the Sierra snowpack to replenish our water supplies,” said California Department of Water Resources Director Mark Cowin. “Major reservoirs are dropping at a time when they typically would be filling with melted snow. We need careful, sparing use of water across the state, because we don’t know when this drought will end.”
April's vanishing snowpack – it was at just 5 percent of normal – was of special concern because, according to the Department of Water Resources, California's snowpack normally is at its peak in early April.
From that point on, it begins slowly melting in spring and early summer, going into streams and reservoirs and supplying 30 percent of the water used by California’s cities and farms, the state reported.
Lack of snow in May at Phillips Station is not as uncommon as the April situation; the Department of Water Resources said the last time snow was found there on May 1 was 2011.
Electronic snowpack readings on Monday show that dry conditions are continuing to deepen.
Statewide, the snowpack on Monday was at 1 percent of normal for this time of year, or three-tenths of an inch – compared to a normal level of more than 16 inches – with a total of 98 stations reporting.
That breaks down as follows for the three different areas of the Sierra:
– Northern Sierra: 2 percent of normal, average snow water equipment of 0.4 of an inch, 30 stations reporting;
– Central Sierra: 1 percent of normal, average snow water equipment of 0.3 of an inch, 42 stations reporting;
– Southern Sierra: 0 percent of normal, average snow water equipment of 0.1 of an inch, 26 stations reporting.
In the Mendocino National Forest, there appears to be no snow at the reporting stations.
Forest officials reported that the two snow reporting stations are at Anthony Peak and Plaskett Meadows.
Department of Water Resources California Data Exchange Center for the two sites goes back to February 1944.
For Anthony Peak, located in the Covelo Ranger District, no snow has been reported since Dec. 21, when there was 7 inches, with 1.5 inches of water content, according to the state's data.
Since 1944, the other instances of no snow being present during snow survey months are as follows: May 1944; May 1947; February 1948; May 1950; January and February of 1963; January 1974; January 1976; February 1977; January, February and April 1981; and May 1986.
For Plaskett Meadows, the last snow measured at the site was on April 3, 2014, based on the state data.
Previous incidences of no snow at Plaskett Meadows during snow survey months since 1944, according to the data exchange center, are as follows: March 1970, May 1990 and February 1991.
