(AP) - The California Department of Water Resources says it will carry out the winter's third survey of the Sierra Nevada's snowpack.
The department says measurements at an elevation of 6,800 feet about 90 miles east of Sacramento will begin Tuesday morning. Results should be available by early afternoon.
Recent electronic readings have revealed a trend of declining water content in the snowpack this wet season.
The department says statewide water content is 19 percent of the historical average for this time of year.
State officials on Tuesday will also release the first water use report card since residents met Gov. Jerry Brown's call to slash consumption by 20 percent in December.
The data help monitor the effectiveness of the state's emergency conservation regulations as California enters a fourth year of drought.
