The reserve was created as part of a flood control project along the Los Angeles River.
It is home to the 'Wildlife Lake,' which was specifically designed to support waterfowl and aquatic life.
The site hosts over 200 species of birds throughout the year, making it a primary destination for local birdwatchers.
The reserve utilizes reclaimed water to maintain its lake and marshland habitats during dry summer months.
It features a specific nesting site area that is periodically restricted to the public to protect sensitive avian breeding grounds.
The Sepulveda Basin Wildlife Reserve is a 225-acre riparian habitat located within the larger Sepulveda Basin Recreation Area in the San Fernando Valley. It features a man-made lake and a system of unpaved trails winding through native willow, cottonwood, and sycamore woodlands. The reserve serves as a critical stopover for migratory birds on the Pacific Flyway, hosting species such as great blue herons, snowy egrets, and various raptors. Established in the 1980s, the site provides a functional ecosystem for local wildlife within an urban landscape. Visitors traverse dirt paths that offer views of the lake, meadow, and marsh areas. Despite its location near major freeways, the interior of the reserve is shielded by dense vegetation, creating a distinct acoustic buffer. The area also acts as a flood control basin managed by the U.S. Army Corps of Engineers.

Stay on marked paths to avoid disturbing nesting wildlife or encountering brush with poison oak.
Attempting to walk near the water's edge in restricted areas or visiting during heavy rain, which can flood the low-lying trails.
Stay on designated trails, keep pets on a leash at all times, and do not feed the local wildlife.
