Big Tujunga Dam is a 244-foot-high (74 m) concrete arch dam in Los Angeles County, California, spanning Big Tujunga Canyon northeast of Sunland, in the foothills of the San Gabriel Mountains. Completed in 1931, it provides flood control and groundwater recharge for the San Fernando Valley .
During the 1969–1985 period, the average flow was 26.1 cubic feet per second (0.74 m 3 /s), [20] and a peak flow of 14,700 cubic feet per second (420 m 3 /s) was recorded on March 4, 1978. [21] After 1985, the USGS stopped measuring discharge but continues to monitor water level in real-time at the La Novia Street bridge. [22]
There, the water is pumped up the Whipple Mountains where the water emerges and begins flowing through 60 mi (97 km) of siphons and open canals on the southern Mojave Desert. At Iron Mountain, the water is again lifted, 144 ft (44 m). The aqueduct then turns southwest towards the Eagle Mountains. There the water is lifted two more times, first ...
It is possible that Juan Rodriguez Cabrillo was the first European to see the San Lorenzo River when in 1542 he sailed the coast of California and stopped in Monterey Bay. [20] Sebastian Vizcaino's 1602-1604 expedition was to further explore the coast and resulted in several detailed maps of the coast, with potential ports for Spain to develop ...
Map of water storage and delivery facilities as well as major rivers and cities in the state of California. Central Valley Project systems are in red, and State Water Project in blue. California's interconnected water system serves almost 40 million people and irrigates over 5,680,000 acres (2,300,000 ha) of farmland. [1]
About 160 square miles of the historic Tulare Lake basin are under water as a result of flooding from a combination of this winter’s atmospheric river storms and a record snowpack that continues ...
Since 1960, when the big pumps at the head of the California Aqueduct in the Delta began their operation, the pattern of water flow in the Delta has been changed considerably leaving the fish confused as to where to go, resulting in many generations dying off because they have not been able to find their way upstream. In 2004, only 200,000 fish ...
Drone footage shot by storm chaser Brandon Clement showed the improvement in water level and snowpack in places such as Folson Lake, Lake Oroville and Donner Pass, since last summer.
