Loveland Dam (also called Sweetwater Falls Dam) is a dam across the Sweetwater River in San Diego County, California. The dam forms long, narrow Loveland Reservoir which stores 25,387 acre-feet (31,314,000 m3) of water. It is operated primarily for flood control and municipal water storage in conjunction with downstream Sweetwater Dam but the reservoir is also open to the public for fishing.The dam stands 203 feet (62 m) high and spans 765 feet (233 m) across the narrow gorge of the Sweetwater River, 2.4 miles (3.9 km) south of Alpine. It is built entirely of concrete and has a thin arch design. Loveland is the younger of the two dams on the Sweetwater River; the other, Sweetwater, was built in 1888 while Loveland was only constructed in 1945. It is named after Chester H. Loveland, president of the California Water and Telephone Corporation, the firm that built it. The Loveland Reservoir is considered a better water storage facility than Sweetwater because of its much smaller surface area (454 acres compared to 960) and comparable capacity, thus it is less vulnerable to evaporation.

El Capitan Dam is an embankment dam or Hydraulic fill dam on the San Diego River in southern California. The dam forms the 112,800-acre-foot (139,100,000 m3) El Capitan Reservoir and serves mainly to supply water to the city of San Diego as well as providing flood control. The dam is connected to the San Diego municipal water system via the El Capitan Pipeline, which extends approximately 30 miles (48 km) to the city. It is the second largest storage facility in San Diego's water supply system, after San Vicente Dam.

El Capitan Reservoir is a reservoir in central San Diego County, California. It is in the Cuyamaca Mountains, about 30 miles (48 km) northeast of the city of San Diego and two miles northwest of the town of Alpine. The reservoir is formed by El Capitan Dam on the San Diego River and has a capacity of 112,800 acre⋅ft (139.1 million m3). The 237-foot (72 m) dam is composed of hydraulic fill and was completed in 1934. The dam is owned by the city of San Diego (Originally owned by the Kumeyaae tribe) and its primary purpose is to supply drinking water. In order to make way for the construction of the dam, the native Kumeyaay people were forcibly relocated to the Capitan Grande Reservation. The amount of runoff that enters the reservoir varies considerably. During a 25-year period, it ranged from 1,000 to 70,000 acre⋅ft (1.2 to 86.3 million m3) per year (39 to 2,700 L/s). The water in the reservoir usually consists of runoff from above the dam, but in years of drought, water is sometimes transferred to it from San Vicente Reservoir, which is the terminus of the First San Diego Aqueduct. According to the City of San Diego's General Plan Seismic Element, Division of Safety of Dams engineers "restricted the maximum water surface of El Capitan Dam to an elevation 30 feet lower than spillway, although permitting the temporary storage of storm inflows above the specified level for short periods." This requirement was added after the 1971 San Fernando earthquake, where "a loss of about 30 feet of dam height resulted" at the Lower Van Norman Dam due to "liquefaction of the hydraulic fill on the upstream side of the embankment". There is limited recreation available at the reservoir. Boating and water skiing are available from May through October. Personal water craft are limited to a designated zone, except when towing someone. Also, the long and narrow north arm of the lake is only open to watercraft on Sundays. Fishing is allowed all year. There is no camping at the lake. The nearest camping site is 8.5 miles (13.7 km) away at Lake Jennings or 12.5 miles (20.1 km) away at Viejas Campground.

The Laguna Fire, also known as the Kitchen Creek Fire or the Boulder Oaks Fire, was a 175,425-acre (70,992 ha) wildfire that burned from September 22 to October 4, 1970, in the Laguna Mountains and East County region of San Diego County in Southern California. It was one of many wildfires in a massive conflagration that spanned across the state from September 22 to October 4, 1970. At the time, it was the second-largest fire in the recorded history of California after the 1932 Matilija Fire (not counting the Santiago Canyon Fire in 1889, which experts estimate burned approximately 300,000 acres (120,000 ha)).
