Dominguez Slough (American English pronunciation: slew or slu)[1] was an endorheic lake and wetland in present-day Gardena, Los Angeles County, California, United States. Known for much of the late 19th century and early 20th century as Nigger Slough, it was renamed Lagunas de los Dominguez in 1938 in reference to the rancho-era Dominguez family.[2] The slough was a "winding body of fresh water that wandered though Gardena and Carson on its way to the mud flats of San Pedro."[2] Gardena is reportedly so named because "of the Laguna Dominguez slough and channel which in summer cuts a green swath across the barren brown landscape—an oasis in the drab, parched landscape between Los Angeles and the harbor area."[3]
