Frank Gehrke, chief of the California Cooperative Snow Surveys Program, will begin the survey at 11 a.m.
just off Highway 50 near Sierra-at-Tahoe Road, about 90 miles east of Sacramento.
The 90-day application period closes January 29, 2018, and applications are due no later than PM on January 29, 2018.
Two workshops are being held, one in Sacramento on December 13 and the other as a webinar on December 15.

Electronic measurements indicate the water content of the statewide snowpack today is 42.5 inches, 196 percent of the May 1 average.Sr isotope ratios (Sr) can provide useful information about water residence time and water mixing in the host rock, as they are not fractionated during calcite precipitation.Laser ablation multi-collector-inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) has rarely been used for determination of Sr isotope signatures in speleothems, as speleothems often do not possess appropriately high concentrations of Sr to facilitate this analysis.Yet the advantages of this approach include rapid data acquisition, higher spatial resolution, larger sample throughput and the absence of chemical treatment prior to analysis.We present LA-MC-ICP-MS Sr isotope data from two speleothems from Morocco (Grotte de Piste) and India (Mawmluh Cave), and we compare linescan and spot analysis ablation techniques along speleothem growth axes.Today's electronic readings from 95 sites in the Sierra Nevada show an average statewide snow water equivalent (SWE) of 45.8 inches, or 164 percent of the historical average for March 30 (27.9 inches).
