The winds drive surface water to the right of the wind flow, that is offshore, which draws water up from below to replace it. The upwelling further cools the already cool California Current. This is the mechanism that produces California's characteristic coastal fog and cool ocean waters. As a result, ocean surf temperatures are much colder in ...
The San Diego River is a 52 mi (84 km) river in San Diego County, California.It originates in the Cuyamaca Mountains northwest of the town of Julian, then flows to the southwest until it reaches El Capitan Reservoir, the second-largest reservoir in the river's watershed at 112,800 acre-feet (139,100,000 m 3).

This facility, which was approved by the San Diego Water Authority, is responsible for providing water for about 8% of San Diego County's water by the year 2020. [25] The facility cost $1 billion to build and is the largest desalination facility in the Western Hemisphere producing up to 50 million gallons (190,000 m 3) of water per day. [26]
The cost of water from the plant will be $100 to $200 more per acre-foot than recycled water (approximately 0.045 cents per gallon), $1,000 to $1,100 more than reservoir water (approx. 0.32 cents per gallon), but $100 to $200 less than importing water from outside the county. [42] As of April 2015, San Diego County imported 90% of its water. [13]
