Corona Municipal Airport (ICAO: KAJO, FAA LID: AJO), formerly L66, is three miles northwest of Downtown Corona, serving Riverside County, California, United States. The airport has a few businesses, such as a cafe, "Flying Academy" flight training center, and aircraft maintenance and repair.Most U.S. airports use the same three-letter location identifier for the FAA and IATA, but Corona Municipal Airport is AJO to the FAA and has no IATA code (Aljouf, Yemen has IATA code AJO).

Temescal Creek (shown on federal maps as Temescal Wash) is an approximately 29-mile-long (47 km) watercourse in Riverside County, in the U.S. state of California. Flowing primarily in a northwestern direction, it connects Lake Elsinore with the Santa Ana River. It drains the eastern slopes of the Santa Ana Mountains on its left and on its right the western slopes of the Temescal Mountains along its length. With a drainage basin of about 1,000 square miles (2,600 km2), it is the largest tributary of the Santa Ana River, hydrologically connecting the 720-square-mile (1,900 km2) San Jacinto River and Lake Elsinore watersheds to the rest of the Santa Ana watershed. However, flowing through an arid rain shadow zone of the Santa Ana Mountains, and with diversion of ground water for human use, the creek today is ephemeral for most of its length, except for runoff from housing developments and agricultural return flows.

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.

The Chino Fault extends along the eastern Chino Hills range region, from Corona in Riverside County to the Los Serranos, Chino Hills area of San Bernardino County in Southern California.

Corona Senior High School (CHS) is a California Distinguished School high school in the city of Corona, California, United States, a growing city in the Inland Empire of Southern California. CHS is one of eight high schools in the Corona-Norco Unified School District.

Chino Creek is a major stream of the Pomona Valley, in the western Inland Empire region of Southern California. It is a tributary of the Santa Ana River.

The Freeway Complex Fire was a 2008 wildfire in the Santa Ana Canyon area of Orange County, California. The fire started as two separate fires on November 15, 2008. The Freeway Fire started first shortly after 9 am with the Landfill Fire igniting approximately 2 hours later. These two separate fires merged a day later and ultimately destroyed 314 residences in Anaheim Hills and Yorba Linda.

Rancho La Sierra (also called La Sierra de Santa Ana) was a 17,769-acre (71.91 km2) Mexican land grant in present-day Riverside County, California, United States. In 1846 governor Pio Pico issued the grant to Bernardo Yorba. The grant lay between Rancho Jurupa and Rancho El Rincon, and included the present-day city of Corona.
