The San Vicente Dam is a concrete gravity dam on San Vicente Creek near Lakeside and 25km northeast of San Diego, California. The dam was built between 1941 and 1943 and creates San Vicente Reservoir for the purpose of municipal water storage, flood control and recreation. Although the reservoir is fed by run-off, its main source is the First San Diego Aqueduct. beginning in June 2009, construction to raise the height of the dam by 117 ft (36 m) to more than double its reservoir size has been underway and is set for completion in 2013.
History
In the late 19th century, San Diego began constructing dams to help supply municipal water and control floods in the San Diego River Basin. In 1928, the Metropolitan Water District of Southern California was created and charged with transferring water from the Colorado River to southern California but San Diego was excluded from the project. Construction on the San Vicente Dam began in anticipation of San Diego receiving water through the Colorado River Aqueduct. The Colorado River Aqueduct was to be supplied with water from Lake Havasu which was created by Parker Dam. Construction of the Colorado River Aqueduct began in 1933 and was completed in 1941, the same year that construction on the San Vicente Dam began. In 1944, the The San Diego County Water Authority (SDCWA) was formed and would soon begin construction on a pipeline from the Colorado River Aqueduct called the San Diego Aqueduct. Construction on the San Vicente Dam was completed in 1943 but construction on the First San Diego Aqueduct, which was supplied by the Colorado River Aqueduct, did not begin until 1945. It was not until 1947 that the First Aqueduct was complete and the San Vicente Reservoir began to receive its water.[2] [3]
Dam-raising project
As part of the SDCWA's $1 billion Emergency Storage Project which began in 2000, the The San Vicente Dam Raise will increased the height of the 220 ft (67 m) dam by 117 ft (36 m) to 337 ft (103 m). This in turn will more than double the reservoir's current capacity of 145,200,000 cu yd (111,000,000 m3) by 245,226,666 cu yd (187,489,239 m3) to a total of 390,426,666 cu yd (298,502,604 m3). In 2006, the SDCWA awarded Montgomery Watson Harza (MWH) with a $20.4 million contract which included the dam's new design and other engineering services during construction. Construction on the dam-raise is being managed by Black & Veatch and Parsons and is also being done in specific stages. The first stage began in June 2009 and consists of preparing the dam's foundation and is expected to be complete in 2010 when the dam-raise will begin. The dam raise is expected for completion in 2010 along with the reservoir's replacement pipeline. The reservoir, which was closed for recreation when construction began, will reopen between 2014 and 2017 depending on when the reservoir is full. The San Vicente Dam Raise itself is estimated to cost $568 million and will be complimented with a new pumping facility and the San Vicente Pipeline which will connect the San Vicente Reservoir to the [San_Diego_Aqueduct#First_Aqueduct|Second San Diego Aqueduct]]. The raised-dam will be constructed with roller-compacted concrete and will be the tallest dam raise in the United States along with the tallest of its type in the world.
