DWR Announces January 3 Snow Survey Results.SACRAMENTO, Calif. -- Results of the January 3, 2008, snow survey by the California Department of Water Resources History
California recognizes many types of water rights. These rights have developed with the State over time. Prior to the Treaty of Guadalupe Hidalgo, signed in 1848, California was part of Mexico. off Highway 50 near Echo Summit are as follows:

The hydrologic cycle consists of the passage of water from the oceans into the atmosphere by evaporation and transpiration (or Branch, says Sierra snow levels are expected to begin at 6000 feet and drop to below 4000 feet through the weekend with another weaker system forecast across Northern California early next week. "The pending storms should provide the State with a much needed helping of snow," said Hinojosa. "We hope to get close to the January average precipitation for the Northern Sierra over the next week."
The next survey will take place in approximately one month's time.

In addition to this single manually measured site, reporters can find real-time readings of statewide water content posted on the Internet at http://cdec.water.ca.gov/cgi-progs/snow/DLYSWEQ
Electronic sensor readings show Northern Sierra snow water equivalents at 64% of normal for this date, Central Sierra at 53%, and Southern Sierra at 69%. Statewide, the percentage of normal is 60.
Importance of Snow Surveying
Snow-water content is important in determining the year's water supply. The measurements help hydrologists prepare water supply forecasts as well as provide others, such as hydroelectric power hydroelectric power: see power, electric; water power.
Electricity produced from generators driven by water turbines that convert the energy in falling or fast-flowing water to mechanical energy. companies and the recreation industry, with much needed data.
The surveys are particularly significant this year because last year's snowpack yielded only 30 percent of the normal water content. Reservoirs are low, as well, with Lake Oroville Lake Oroville is a large man-made reservoir lake in central Northern California in the foothills of the Sierra Nevada.
It is located east of the city of Oroville, California in Butte County. The lake has a capacity of 3,537,580 acre feet (4. holding only 35 percent of its 3.5 million acre foot capacity, 55 percent of average for this time of year. Because less-than-normal water supply conditions exist, the initial State Water Project allocation for 2008 was placed at 25 percent of water contractors' requested amounts.
Monitoring is coordinated by the Department of Water Resources as part of the multi-agency California Cooperative Snow Surveys Program. Surveyors from more than 50 agencies and utilities visit hundreds of snow measurement courses in California's mountains each month to gauge the amount of water in the snowpack.
The Department of Water Resources operates and maintains the State Water Project, provides dam safety and flood control and inspection services, assists local water districts in water management and water conservation planning, and plans for future statewide water needs.
