NID snowpack reports showing average year

The 2001-02 precipitation year is turning out to be very average in both total precipitation and snowpack water content.

Precipitation on the Nevada Irrigation District watershed near the 5,650-foot-elevation Bowman Reservoir reached 48.33 inches as of Feb. 27, 100 percent of average for the date.

“With February being somewhat dry, we are fortunate to still be near average for both our precipitation and snow water content,” said NID operations supervisor Sue Sindt.

“We have continued to add to our storage and are getting closer to the historical average,” she said. “At this point in the season, we are in a better water supply position than we were last year.”

Last season was drier, with precipitation as of March 1, 2001, measured at 61 percent of average and the snowpack with 74 percent of average water content.

In the official March 1 snow survey, conducted Tuesday and Wednesday, NID snow surveyors measured snowpack depth and water content on six snow courses, ranging in elevation from 4,850 feet to 7,800 feet.

Average water content for the five highest elevation snow courses was measured at 30.4 inches, 100 percent of the historic average.

As of Feb. 27, NID’s 10 reservoirs held 159,480 acre feet of water, which equals 64 percent of capacity and 95 percent of the March 1 storage average. An acre-foot equals one acre covered one foot deep.

A member of the California Cooperative Snow Survey, NID conducts three official snow surveys each year. Results of the snow surveys are used to predict water availability locally and statewide.
