The lagoon is a designated California Department of Fish and Wildlife protected area for specific avian species.
Colorado Lagoon is a restored saltwater tidal wetland located in Long Beach, California, serving as a critical habitat for coastal wildlife. The site features a sandy beach area monitored for water quality, offering a calm alternative to the open ocean surf. A designated model-boat sailing program operates here, utilizing the lagoon’s protected, wind-sheltered waters. Extensive ecological restoration efforts have connected the lagoon to the Alamitos Bay to improve tidal flushing and water circulation. The park grounds include walking paths, picnic facilities, and educational signage detailing local flora and fauna. It serves as a stopover for migratory birds along the Pacific Flyway. Shallow water depths make the area accessible for wading and youth swimming.
