Birds, such as herons, egrets, and ducks, can be seen wading in the shallow waters, searching for food. Fish, such as steelhead trout and salmon, use the creek as a spawning ground. Mammals, such as raccoons, skunks, and opossums, can also be found in the area. Portola Bridge Creek is also an important part of the local community. The creek provides a place for residents to connect with nature and enjoy the outdoors. The creek is surrounded by parks and open spaces, providing opportunities for hiking, biking, and picnicking.
