The San Gabriel Valley is dominated by a dense grid of infrastructure and water management systems designed to handle the runoff from the nearby mountains. The Santa Fe Flood Control Basin stands as a massive geographic anchor in the northwest, feeding into the San Gabriel River. This landscape is defined by its complex drainage network, where natural waterways like Walnut Creek and Puente Creek are augmented by engineered features such as the San Jose Creek Diversion Channel and Hacienda Channel.
