What is the Santa Ana drainage basin?
The Santa Ana drainage basin has a diversity of terrain, ranging from high peaks of inland mountains in the north and east, to the hot, dry interior and semi-desert basins of the Inland Empire, to the flat coastal plain of Orange County. Although it includes areas of alpine and highland forest, the majority of the watershed consists of arid desert and chaparral environments. Due to low regional rainfall, the river carries only a small flow except during the brief winter season, when it is prone to massive flash floods. The San Jacinto River, which drains the southern half of the watershed, rarely reaches the Santa Ana except in extremely wet years. A wide variety of animal and plant communities depend on the riparian zones and remnant wetlands along the Santa Ana River.
Why did the Santa Ana River basin deplete?
Although no missions were actually located along the Santa Ana River or within the watershed, the river basin was nearly depleted of native people because the Spanish forced them to work at nearby missions, including Mission San Gabriel Arcangel and Mission San Luis Rey. The affected tribes were usually renamed after the missions, resulting in tribal names such as Gabrieliño and Luiseño. Difficult working and living conditions and European diseases such as smallpox killed much of the native population during the roughly 50-year-long Mission Period. The Secularization Act of 1833, passed by the newly independent country of Mexico, eventually brought an end to the Mission Period. The post-Mission Period native population was almost entirely devastated. The population was very little, their native religions were nearly lost, and most of their land had been taken by Spanish settlers. Although the Mexican government's original intention with the Secularization Act was to provide the Native Americans with their own land and property, most of the provisions made by the act never actually happened. Spanish settlers continued to press into the remaining tribal lands, and eventually, the tribes were forced into the surrounding desert lands or into the high mountains.
What is the Santa Ana River?
The Santa Ana River drains the largest watershed of California's South Coast region, covering 2,650 square miles (6,900 km 2) in parts of San Bernardino, Riverside, Orange and Los Angeles Counties. Although the river does not pass through Los Angeles County, some of its tributaries, including San Antonio Creek extend into it. The watershed consists mainly of high mountain ranges that surround and divide large, dry alluvial valleys. The San Gabriel, San Bernardino and San Jacinto Mountains encircle the arid Inland Empire lowland on the north and east. The Santa Ana Mountains and Chino Hills divide the Inland Empire from the Orange County coastal plain; the Santa Ana Canyon is the only natural break in the range between the two lowlands. The southern part of the watershed, drained by the San Jacinto River into Lake Elsinore and via Temescal Creek into the Santa Ana River, constitutes some 45% of the total area and extend its boundaries as far south as the Colorado Desert at Anza-Borrego Desert State Park. The river has over 50 named tributaries, most of which are intermittent streams.
Why was Santa Ana Canyon cut?
The cutting of Santa Ana Canyon across the Peninsular Ranges is attributed to the wetter Southern California climate during the Wisconsinian Glaciation and earlier ice ages, during which rivers in Southern California were substantially bigger in volume. The Santa Ana River, which existed prior to the creation of the Peninsular Ranges, maintained its course as an antecedent stream due to its increased erosive power. The canyon was eroded through bedrock that today divides the groundwater basins of the Inland Empire and the coastal plain. Because groundwater in the watershed generally flows from east to west, it is forced to the surface at the bedrock "sill" of Santa Ana Canyon, resulting in a perennial stream that prior to development flowed freely across the coastal plain to the Pacific. During this period, the Santa Ana changed course multiple times, eroding now-dry wind gaps in the Peninsular Range and the coastal mesas around Huntington Beach and Newport Beach.
