Wolf Creek begins above Grass Valley, California, flows through the city, turns roughly south, and eventually joins the Bear River at Nevada County’s southern border. The creek and its tributaries drain a significant portion of southwestern Nevada County. Wolf Creek has historically been neglected and under-appreciated, but that has begun to change as Wolf Creek Community Alliance works to preserve and protect Wolf Creek and its watershed for the benefit of present and future generations.
