Prado Reservoir is a reservoir in northwestern Riverside County and southwestern San Bernardino County, a couple of miles west of the city of Corona, in the U.S. state of California. The reservoir has a capacity of 362,000 acre-feet (447,000,000 m3) and is formed by Prado Dam on the Santa Ana River. The dam is composed of rock-fill and has a height of 106 feet (32 m) above the original streambed. It was built on the upper end of the Lower Santa Ana River Canyon, where there is a natural constriction in the river. It is below 2,255 square miles (5,840 km2) of the 2,450-square-mile (6,300 km2) Santa Ana River watershed. The dam was built by the United States Army Corps of Engineers and was completed in 1941. Prado Dam and Prado Reservoir provide flood control and water conservation. Their operation is coordinated with the facilities upstream. Prado Reservoir is not a storage reservoir, so water is released as quickly as possible while still allowing for groundwater recharge. When the water level reaches the top of the buffer pool, whose size changes depending on time of year, water is released at the maximum rate that the downstream channel will safely allow. As of 2006, the capacity of the channel is 5,000 cubic feet (140 m3) per second (140 m³/s), but channelization will eventually increase the capacity to 30,000 cubic feet (850 m3) per second (850 m³/s). During flood season, the buffer pool only has a capacity of 8,437 acre-feet (10,407,000 m3), while outside of flood season, the capacity increases to 25,760 acre-feet (31,770,000 m3). Since this is 2.3 and 7.1 percent of the reservoir's total capacity, respectively, the reservoir is usually fairly empty.

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. Its primary purpose is flood control and it is the downstream element of the Santa Ana River's flood control system, which is a natural constriction about 30.5 mi (49.1 km) upstream from the ocean. The area upstream from the dam contains 2,255 sq mi (5,840 km2) of the watershed's 2,650 sq mi (6,900 km2). The dam's construction was authorized in 1936 and the flood of 1938 demonstrated its necessity. Construction was completed in 1941. Prado Flood Control Basin also provides water storage for groundwater recharge operations.
