About: Dominguez Channel

Dominguez Channel is a 15.7-mile-long (25.3 km) river in southern Los Angeles County, California, in the center of the Dominguez Watershed of 110 square miles (280 km2). The watershed area is 96% developed and largely residential. Subsurface storm drain tributaries and open flood control channels flow into the channel. Lower Dominguez Channel, for the last few miles before reaching the ocean harbor, becomes an estuary mixing freshwater and ocean water together, overlying a wetland soil between uncemented boulder levees that serves as wildlife habitat and wildflower habitat for migratory native birds and native wetland vegetation.
