Victoria Park Golf course
Victoria Park Golf course is located along the Dominguez Channel in the City of Carson.
Madrona marsh
Madrona Marsh is an island of wilderness located in the City of Torrance. It is one of the last remaining vernal marshes and is fed entirely by stormwater.
Injection well
Shown here is one of the injection wells in the Dominguez Gap Barrier Project located in the southern portion of the watershed. These wells protect a significant portion of the watershed's drinking water supply from ocean water, which constantly attempts to migrate into existing aquifers. Treated imported and reclaimed water is injected deep into the underground aquifers to block this inland migration of saltwater. http://ladpw.org/wrd/barriers
