. Fed primarily by rainwater and snowmelt (in winter and spring), the Donald C. Tillman Water Reclamation Plant in Van Nuys (in summer and fall), and urban discharge, it is one of the few low-elevation perennial rivers in Southern California. Some water usually reaches the ocean, even in the driest summers; although there are historical accounts of the river running dry, there has been constant flow of the river every month since recording of stream flow began in 1929. This is helped by the concrete channel, which limits absorption of water into the earth. Flow, while generally low in volume, can be extremely brisk even in summer.

"...until 1825 it was seldom, if in any year, that the river discharged even during the rainy season its waters into the sea. Instead of having a river way to the sea, the waters spread over the country, filling the depressions in the surface and forming lakes, ponds and marshes. The river water, if any, that reached the ocean drained off from the land at so many places, and in such small volumes, that no channel existed until the flood of 1825, which, by cutting a river way to tide water, drained the marsh land and caused the forests to disappear."

When the Owens Valley Irrigation District did not succeed, they created three smaller groups in order to try to bargain. These groups were turbulent in their efforts; resorting to violence, trying to get the attention of state and national press, and calling for politician interference to support their demands for more compensation. This conflict was so highly disputed that the national press referred to it as "California's Little Civil War."

Despite the heavy flood flows of the river during winter months, the LA river has become a refuge for marginalized communities, such as migrant, homeless, and diverse sociocultural communities. For a time, the river itself was a geographical divide between East L.A., which is largely Latino, and predominantly white, wealthy West L.A. These minority groups established themselves along the banks of the river, using fish for food. A distinguished link between the LA river and marginalization can be seen through time as a 1909 New York Times article describes these communities as poor transient communities that consume diseased fish to sustain themselves. Remediation efforts in order to tame the river along with the construction of highways in the 1950s and 1960s displaced hundreds of thousands of individuals. These implications lead to poor air quality and increased exposure to diseases that inhibit good health.

These three species are known today as the Chinook salmon, steelhead/rainbow trout, and Sacramento pikeminnow. The native species of the Los Angeles River were extirpated by the conversion of the natural riverbed into a concrete trapezoidal channel in 1938.

Revitalization

The ongoing efforts to revitalize the river began in earnest in approximately 2002. A number of city and county departments, committees and non-profit organizations have led the revitalization efforts. Since the 1938 floods and the subsequent concreting of the river channel, actual restoration of the River to its natural state is no longer possible or necessarily desirable, in most of the 51 mile river, lest new flooding occur. Studies in the 1980s included a freeway to be used during the dry season to alleviate traffic congestion, and use as a path for hovercraft. In 2011, the creation of the L.A. River Recreation Zone legalized recreational use in the area. Since then, there have been countless projects to restore recreational use, including a 2.5 mile section of the Glendale Narrows that opened to the public for unrestricted recreational use between

, the City of Los Angeles' Department of Public Works - Bureau of Engineering issued a request for proposals in 2005 for the preparation of a Revitalization Master Plan, which would identify proposals that would make the Los Angeles River a "front door" to the city, and support civic activities. The city's Los Angeles River Revitalization Master Plan was adopted in 2007. One of the key recommendations made by the master plan was the establishment of a non-profit development corporation, with a board appointed by the then Mayor Antonio Villaraigosa and certain members of L.A. City Council, to carry out many of its recommended projects. In September 2009, the first board meeting of the LA River Revitalization Corporation was held. Startup funding was provided by the CRA. Harry B. Chandler was elected first chair of the board, and Omar Brownson was hired in 2010 to be the founding executive director. The first development project undertaken by LARRC was creating a public-private partnership to create the first pedestrian, bike and equestrian bridge across the river. Developer Mort La Kretz provided the seed financing for the bridge, which was built next to the 5 freeway in the Elysian Valley by the Los Angeles Bureau of Engineering and completed in 2020. On July 23, 2013, the LARRC announced a goal of completing a continuous 51-mile (82 km) greenway and bike path along the river by the end of the decade. The path is envisioned to be the central focus of a linear recreational park as well as providing an alternative transportation path through Los Angeles. The ''

taking on additional responsibilities. In 2019, Gehry revealed to Alta Magazine that he is working on designing several projects along the River, including a cultural center in Southgate. On September 13, 2013, the Army Corps of Engineers recommended a $453 million plan to restore nearly 600 acres of wildlife habitat – much of that located between Griffith Park and Lincoln Heights – as the best option to restore the river's ecosystem while preserving the flood protection provided by the concrete encasement. Subsequently, all Federal funding for the plan has been on hold. In early 2016, there was some dispute as to federal funding for river cleanup after winter storms. As part of Proposition 68 in California in June 2018, later that year, grants were given for the cleanup of invasive plants along part of the river. As a result, in 2018, Los Angeles and its LARiverWorks policy team had a project underway for "every mile of the river within city limits, aiming to improve connectivity, increase open space, and restore habitat. New bridges and trails will accommodate people on foot, bikes, or horseback." Plans to cleanup 11 miles of river north of downtown Los Angeles, in the hopes of attracting

2020 LA River Master Plan

In 2020, Los Angeles County released an updated LA River Master Plan detailing plans for the river over the next 25 years. The current plan addresses 9 goals related to flood risk, parks, ecosystems, access, arts and culture, housing, engagement and education, water supply, and water quality. The plan for decreasing flood risk consists of preserving and increasing flood risk capacity, reducing flow into the river, incorporating climate change research, and increasing emergency planning, public awareness, and management practices. In order to create inclusive, open areas, LA county's actions include making 51 continuous miles of open space, finishing the LA River Trail, providing amenities, implementing multi-use functionality, and promoting public safety. The third goal of the 2020 LA River Master Plan is to support flourishing ecosystems by increasing habitat and ecosystem function, improve plant biodiversity including native species, connecting habitat to support wildlife, and increasing environmentally-friendly practices. The LA county goal of equal access to the river is outlined by creating access points and gateways and promoting safe transportation to the river. The objective of enhancing arts and culture is planned to be achieved by creating a 51-mile arts and culture corridor, identifying and supporting cultures, and involving artists and cultural groups in the design process. The next goal outlined in the LA River Master Plan addresses impacts to the housing economy and the homeless community through incorporating the Affordable Housing Coordinating Committee in planning, creating mapping and assessment tools, increasing affordable housing, securing funding, and enhancing outreach to homeless populations. The actions to enhance engagement and education include providing spaces for all ages to learn, developing new educational materials, involving aspects from indigenous peoples, and promoting the river as an economic asset to nearby communities. The eighth goal in the master plan is to improve water supply through diverting and treating stormwater and dry weather flows before they flow into the river, supporting efficient water usage, creating better operations, maintenance, and measures. The final goal is to improve water quality by developing water quality projects, working with watershed management groups, raising public awareness, and improving facility operations and maintenance.


Friends of the Los Angeles River

Friends of the Los Angeles River (FoLAR) was founded in 1986 by poet and activist Lewis P. Macadams. Originally deemed a "40-year artwork to bring the River back to life," FoLAR was the first organization advocating for habitat restoration and public access on the LA River. One FoLAR's more prominent ongoing projects is the annual Great LA River Cleanup, which began in 1988 with a group of less than twenty people. In 2017, the Great LA Cleanup had up to 10,000 volunteers over three weekends covering the upper, middle, and lower sections of the River. In 2016, an estimated 5,000 volunteers took place in the annual cleanup, including the mayor and several elected officials. In 2018, more than 6,000 volunteers removed more than 60 tons of trash at nine sites along the Los Angeles River.Great L.A. River CleanUp marks 30 years
Park LaBrea news / Beverly Press, April 11, 2019
In 2019, the FoLAR cleanup was the largest river cleanup in the United States. The cleanup marked 30 years in 2019. By the summer of 2019, kayaking in Los Angeles in the river had become common. As of 2018, FoLAR has adopted a year-round cleanup model through partnerships with other environmental organizations like Heal the Bay, and through service opportunities for corporate groups and large organizations through River Makers program. In 2012, FoLAR raised a $1 million donation to support the completion of the ARBOR study by the
