Lower San Gabriel River Watershed

The upper part of this watershed features mountains, rivers, and woodland habitats in addition to more urban cities closer to the Pacific Ocean.

The San Gabriel River Watershed originates in the steep terrain of the San Gabriel Mountains, where snowmelt and natural springs converge to form a network of streams that ultimately reach the Pacific Ocean. Extending across 1,236 miles of waterways, the watershed supports a population exceeding 2.3 million people. Effective stewardship of this resource depends on a comprehensive understanding of its ecological condition and the human and environmental forces that influence it. The watershed plays an essential role in regional water capture, stormwater management, and the restoration of degraded habitats. Its continued protection will determine not only the health of the natural systems it supports, but also the resilience of the communities that depend on it. This watershed is a vital ecological area in southeast Los Angeles County, with ongoing efforts focusing on water quality improvement, community engagement, and sustainable resource management practices.

With a Master’s in Geography, Resource Management and Environmental Planning, I enjoy analyzing the processes and spatial patterns of human-environment interaction and addressing issues of sustainability to solve real-world problems. My favorite part of this role is participating in community engagement events and making connections between land use, stormwater, and ecological health. I love spending time along the San Gabriel River, watching for green sea turtles.
