Prado Dam is an earth-fill dry dam across the Santa Ana River at the Chino Hills near Corona, California in Riverside County with the resulting impounded water creating Prado Flood Control Basin reservoir. The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon.
Water level elevation in the lake is maintained at a maximum of 280 feet (85 m) above sea level, 35 feet (11 m) lower than the dam's maximum of 315 feet (96 m) spillway to ensure safe operations. [3] The lake level can fluctuate significantly, depending upon the amount of runoff received from the San Dieguito River drainage basin. [ 4 ]
The Russian River at Guerneville reached a flood stage of 45 feet, about 3.5 feet lower than the record 48.56 feet stage in 1986, but still the second-highest stage since 1995. The flooding of the Russian River caused significant damage to farmland and vineyards along the banks of the river including the city of Guerneville. [3]
The oldest rocks in California date back 1.8 billion years to the Proterozoic and are found in the San Gabriel Mountains, San Bernardino Mountains, and Mojave Desert.The rocks of eastern California formed a shallow continental shelf, with massive deposition of limestone during the Paleozoic, and sediments from this time are common in the Sierra Nevada, Klamath Mountains and eastern Transverse ...
