The City of Riverside is part of the Santa Ana Watershed which catches stormwater from a 2,650 square mile region and channels it into the Pacific Ocean at the City of Huntington Beach. It stretches from the peaks of the San Bernardino and San Gabriel Mountains, through the coastal plains in Orange County all the way to the Pacific Ocean. The Santa Ana River (River), flowing over 100 miles, drains the largest coastal stream system in Southern California including parts of Orange, Riverside and San Bernardino Counties, as well as a sliver of Los Angeles County. The total length of the River and its major tributaries is about 700 miles, one of the largest River systems in California.
Did you Know? A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place.
