Machado Lake To Shine In 2017


With more than 90% of its land area developed, Los Angeles’ Dominguez Channel Watershed is undoubtedly the southland’s most impervious. Located in the southern portion of the Los Angeles Basin, the watershed includes more than eight cities as well as portions of unincorporated LA County. Its 70,000 acres of drainage area include several bodies of water including the Wilmington Drain, Torrance Lateral and Machado Lake, which drain directly into the LA Harbor, and the Dominguez Channel, which begins in Hawthorne and discharges into the LA Harbor in the east basin.

One of the areas of the Dominguez Channel Watershed that has retained its natural environment is Machado Lake, located in the Ken Malloy Harbor Regional Park. This lake, and the surrounding park area, has been undergoing a massive rehabilitation effort for the last several years.  The Machado Lake Ecosystem Rehabilitation Project is the second phase of a two-phase project designed and implemented by the City of Los Angeles and funded by Proposition O. The primary goal of this two-phase rehabilitation project is to improve the water quality in the 45-acre Machado Lake and enhance the surrounding natural habitat and recreational features of the 290-acre park.

The first phase of this project, the Wilmington Drain Multi-Use Project, was completed in 2015. This phase improved water quality in the channel, enhanced natural habitat and created the Harbor City Greenway, which now provides residents with 27 acres of green space.

The second phase of this project, the Machado Lake Ecosystem Rehabilitation Project, is set to be completed this spring. It includes the dredging of 239,000 cubic yards of lake sediment, the capping of the lake’s bottom, the construction of an oxygenation system and the rehabilitation of the southern dam structure. Another improvement will be the installation of five continuous deflection separation systems at the lake’s storm drain inlets to screen, separate and trap trash and debris from stormwater and dry weather flows before entering Machado Lake. Lastly, the project will improve the park by removing invasive plants and replanting native vegetation and enhancing the park’s recreational elements by building new piers, fencing and pedestrian walkways.

So stay tuned for information about the ribbon cutting for the Machado Lake Ecosystem Rehabilitation Project in 2017. It’s Machado Lake’s turn to shine!

    I got a tour of the project ten days ago from Senior Project Manager Walid Azar and City of LA/Rec and Parks management assistant Emily Kent. After decades of decline at the park, this project-particularly the sophisticated water quality management system-is really impressive! While Lake Machado is most notorious for Reggie the alligator, around three hundred species of birds have been spotted at the park, and the wetlands draining into the lake and receiving its outflow are important habitat for a range of creatures. Ken Malloy-who more or less single-handedly created the park-is smiling, somewhere! Kudos to Mitch Heindl, Martin Byhower, and the many others who have advocated for this park over the years!
