San Leandro Creek (Spanish : Arroyo de San Leandro) is a 21.7-mile-long (34.9 km) year-round natural stream in the hills above Oakland in Alameda County and Contra Costa County of the East Bay in northern California.
It flows along the east face of the hills, east of Oakland and San Leandro. It runs into Upper San Leandro Reservoir and then Lake Chabot, both reservoirs are North of the unincorporated town of Castro Valley. It then flows through the city of San Leandro, and after crossing Hegenberger Road just north of Oakland International Airport on into San Leandro Bay of San Francisco Bay.
Although it is channeled and culverted in places, it is remarkable among East Bay streams for being mostly uncovered throughout most of its course. It is joined by Indian Creek, and then at Upper San Leandro Reservoir it is joined by Moraga Creek, Redwood Creek, Buckhorn Creek and Kaiser Creek, then just below the spillway by Miller Creek. At Lake Chabot in Anthony Chabot Regional Park it is joined by Grass Valley Creek, then descends to San Leandro Bay.
The Redwood Creek tributary is protected by Redwood Regional Park, which contains the largest remaining natural stand of coast redwood (Sequoia sempervirens) found in the East Bay.
The creek terminates in Arrowhead Marsh in Oakland, one of the few marshlands left in the East Bay. The marsh formed in San Leandro Bay between 1855 and 1895 from sediments washed down San Leandro Creek during construction of the Lake Chabot dam and also from the logging of the San Antonio Forest.

San Leandro Creek was formerly named Arroyo de San Leandro, likely named by the Spanish for St. Leander, 6th-century archbishop of Seville, "Apostle of the Goths".It was crossed by El Camino Viejo now, State Route 185.
The creek is known for having been the site of the first rainbow trout hatchery in the world, drawing on the locally native variety of the species. The fish raised in this hatchery were sent as far away as New York.Although rainbow trout (Oncorhynchus mykiss), was initially identified in 1792 in Kamchatka, Siberia by Johann Julius Walbaum, William P. Gibbons, founder of the California Academy of Sciences, believed in 1855 that he had discovered a new species of trout in San Leandro Creek, which he named Salmo iridea (now the coastal rainbow trout subspecies Oncorhynchus mykiss irideus). The site was then declared a California Historical Landmark.
In 1874 work began on Lake Chabot Dam and it was completed in 1875, forming a 315-acre (127 ha) lake. Lake Chabot serves as a standby emergency water supply but was opened to limited recreation in the 1960s. Four miles upstream, a second dam built in 1926 formed San Leandro Reservoir.
It sustains the redwood groves in the unincorporated town of Canyon, California and was formerly lined with numerous oaks and willows in its lower course.
Historical records indicate that Chinook salmon (Oncorhynchus tshawytscha) occurred in at least two San Francisco Bay Area watersheds, San Leandro Creek in Alameda County, and San Mateo Creek in San Mateo County.In the 1870s, “quinnant”, or Chinook salmon were reported from lower San Leandro Creek and persisted in Lake Chabot for several years following the completion of Lake Chabot Dam in 1875. California Department of Fish and Game Warden George Smalley reported runs of coho salmon (Oncorhynchus kisutch) and steelhead trout (Oncorhynchus mykiss irideus) in San Leandro Creek “…in the early days” and “…that after the completion of the Upper San Leandro Reservoir a run still persisted to the base of the dam for many years”. Leidy considered this single historical account of coho in the creek "reliable...since we believe that suitable habitat was present in the watershed." As mentioned above, Gibbons discovered rainbow trout in San Leandro Creek in 1855. Thus, three species of Oncorhynchus once inhabited San Leandro Creek.
Today, Lake Chabot's rainbow trout are hatchery fish, but the rainbow trout in San Leandro Reservoir are descended from native steelhead which were trapped when San Leandro Dam was constructed on Redwood Creek in 1926. The San Leandro trout have maintained genetic integrity with native coastal rainbow trout since they have not been mixed with hatchery trout, and were used in a 1983 reintroduction of steelhead to Wildcat Creek in Tilden Regional Park.
The San Lorenzo River is a 29.3 miles (47.2 km) long river whose headwaters originate in Castle Rock State Park in the Santa Cruz Mountains and flow south by southeast through the San Lorenzo Valley before passing through Santa Cruz and emptying into Monterey Bay and the Pacific Ocean.
The rainbow trout is a trout and species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead is an anadromous (sea-run) form of the coastal rainbow trout(O. m. irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to fresh water to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.
Coyote Creek is a river that flows through the Santa Clara Valley in California, United States.
Waddell Creek is the name given to both the creek and the watershed that run through Big Basin Redwoods State Park in Santa Cruz County, California. The Waddell Creek mainstem is formed by the confluence of East and West Waddell Creeks, and empties into the Pacific Ocean at Waddell Beach, just south of Año Nuevo Point.
Stevens Creek is a creek in Santa Clara County, California. The creek originates in the Santa Cruz Mountains on the western flank of Black Mountain in the Monte Bello Open Space Preserve near the terminus of Page Mill Road at Skyline Boulevard. It flows southeasterly through the Stevens Creek County Park before turning northeast into Stevens Creek Reservoir. It then continues north for 12.5 miles through Cupertino, Los Altos, Sunnyvale and Mountain View before emptying into the San Francisco Bay at the Whisman Slough, near Google's main campus.
Temescal Creek is one of the principal watercourses in the city of Oakland, California, United States.
Lagunitas Creek is a 24 miles (39 km)-long northward-flowing stream in Marin County, California. It is critically important to the largest spawning runs of endangered coho salmon in the Central California Coast Coho salmon Evolutionary Significant Unit. The stream's headwaters begin on the northern slopes of Mt. Tamalpais in the Coast Range and terminate in southeast Tomales Bay, 1.5 miles (2.4 km) northwest of Point Reyes Station, California. Lagunitas Creek feeds several reservoirs on Mt. Tamalpais that supply a major portion of the county's drinking water.
Alameda Creek is a large perennial stream in the San Francisco Bay Area. The creek runs for 45 miles (72 km) from a lake northeast of Packard Ridge to the eastern shore of San Francisco Bay by way of Niles Canyon and a flood control channel.
