Aliso Canyon is a 6.5-mile (10.5 km) canyon located in Orange County, California in the United States. The canyon is a water gap across the San Joaquin Hills carved out by Aliso Creek, possibly as recently as the last ice age. Located in a semi-arid climate, it supports a variety of plant communities – mainly chaparral and coastal sage scrub – and native animals, some endangered. The canyon's northern divide once formed a formidable boundary between the indigenous Acjachemen and Tongva. Many Acjachemen archaeological sites have been found in the canyon. The fertile alluvial soil and grasslands of Aliso Canyon was used for orchards and grazing from Spanish conquest of the region until the early 20th century. Since the 1970s, the canyon has been the centerpiece of Aliso and Wood Canyons Wilderness Park. Aliso Canyon has also suffered environmental damage in recent years. Upstream urban development since the 1950s has increased urban runoff into Aliso Creek, causing severe erosion throughout the valley floor. Pollution has also harmed the area's riparian zones. There have been plans to fix these problems, mainly by constructing drop structures to control erosion.

Los Alamos Canyon Creek, a stream or arroyo, tributary to San Mateo Creek, in the Cleveland National Forest in Riverside County, California. Its source is at an altitude of 2300 feet, in a canyon on the south face of the ridge of Elsinore Mountains that descends to the southeast from Elsinore Peak. The creek descends southward for a short distance then turns southwest for 4 miles where it turns west for 3 miles down Los Alamos Canyon to its confluence with San Mateo Creek at an elevation of 1312 feet.Los Alamos Canyon Creek has one named tributary Wildhorse Canyon Creek but has two unnamed arroyos descending from the Elsinore Mountains. and one that drains the western Santa Rosa Plateau and the east slope of the Tenaja Mountain highland and descends to the north to join the creek where it turns to the west.

Bell Canyon is a major drainage of the Santa Ana Mountains in Orange County, California in the United States. Bell Creek (also known as Bell Canyon Creek or Arroyo de las Campanas) flows about 14.4 miles (23.2 km) in a southerly direction to its confluence with San Juan Creek. The Bell Canyon drainage is located to the east and parallel to Cañada Gobernadora, and to the south of Trabuco Creek. After Trabuco Creek, it is the second largest tributary of San Juan Creek in terms of length and its watershed area of 26 square miles (67 km2). Most of Bell Canyon consists of wilderness in the Cleveland National Forest and Ronald W. Caspers Wilderness Park. The valley is more than 1,000 feet (300 m) deep and averages a mile (1.61 km) wide, and is joined by the major tributaries of Dove Canyon, Crow Canyon and Tick Creek.

Cristianitos Canyon Creek, a stream or arroyo, tributary to San Mateo Creek, in the Santa Ana Mountains. its source is within Orange County, California. Its source is at an altitude of 800 feet, at the head of Cristianitos Canyon, in the foothills of the Santa Ana Mountains, in Orange County. It flows southwestward down Cristianitos Canyon, then turns south towards its confluence with San Mateo Creek, at an elevation of 75 feet, in San Diego County.Along its course it has two major tributaries that come in from the left bank from the Santa Ana Mountains southwest and south of the Verdugo Potrero. First Gabino Canyon Creek, 7 miles long, that arises at an elevation of 1840 feet in the Santa Ana Mountains, in the extreme southwestern part of Riverside County, a mile north of the San Diego County line and flows southwest, adding the waters of La Paz Canyon Creek on its way to its confluence with Cristianitos Creek, at the mouth of Cristianitos Cahyon, at an elevation of 301 feet in Orange County. Second is Talega Canyon Creek, 10 miles long, that also arises in the Santa Anna Mountains, in southwestern part of Riverside County at altitude 2000 feet above sea level.

Trampas Canyon is a short tributary of San Juan Creek in southern Orange County the U.S. state of California. It rises in forks on steep slopes of the southern Santa Ana Mountains (33.4883597°N 117.5933813°W / 33.4883597; -117.5933813), and flows north to where it is dammed by Trampas Canyon Dam (USGS San Clemente Quad 7½"). Trampas Canyon 1795-006 Dam (33.498359°N 117.587548°W / 33.498359; -117.587548) forms a small lake that branches into four forks running east–west. Exiting the dam, the creek flows north and turns slightly to the west, where it joins San Juan Creek on the left bank, near the confluence of Cañada Gobernadora (33.3053°N 117.3458°W / 33.3053; -117.3458). Trampas Canyon Creek is ephemeral and only flows during storm events or while Trampas Canyon Dam is releasing, and is not a primary tributary of San Juan Creek.A study was prepared in 1999 by the City of San Juan Capistrano, and it was found that a failure of the earthen Trampas Canyon Dam would do more damage to the lower course of San Juan Creek than for a 100 year flood. A failure would cause a floodwave over 0.5 miles (0.80 km) wide to rush down the lower 4.7 miles (7.6 km) of San Juan Creek to Doheny State Beach, flooding parts of San Juan Capistrano and Dana Point. A 100-year flood would cause a slightly smaller inundation.
