Bixby Slough (American English pronunciation: “slew/slu”[1]) was an ancient wetland in Los Angeles County, California. Also known as Machado Lake, the slough was a "large freshwater wetland in the Carson-Harbor City-Wilmington area"[2] that flowed into San Pedro Bay about three or four miles (5 km) west of Dominguez Slough.[3] Originally a "network of sloughs, nondescript streams and bogs in the harbor district,"[4] over time the Port of Los Angeles was carved “out of the mud flats and shallow waters that edged the ranchos of San Pedro and Palos Verdes.”[5] About 90 percent of wetland ecosystems in Los Angeles County have been destroyed, with the losses in the highly urbanized South Bay "especially acute" and one biologist calling the draining of Bixby Slough and other harbor-area wetlands a “"wipeout".[6]
