Dolly Varden, Arctic char, and steelhead trout can be found in streams of the Izembek Refuge. Beginning in mid-summer, red, pink, and chum salmon return to spawning grounds within the Refuge. Hundreds of thousands of salmon begin and end their life cycles within the Refuge, enriching streams and lakes with nutrients they bring from the sea. Silver salmon arrive in early fall. Since the 1960's, an annual Silver Salmon Derby has been held in Cold Bay each Labor Day Weekend, to raise funds for the local Emergency Medical Technician Squad. It is quite the event for the small community of less than 100 residents.
