This town started as a Russian settlement named St George in 1786. A Native fishing village spread over the area now called Kasilof. They are mostly Kanai Indians, a branch of the great Athabascan family.
Fishing is the main industry.
The Kasilof River drains Tustumena Lake into the Cook Inlet. It is the largest lake in the Kenai Peninsula . Beaches in the area are well-known for razor clams. A hatchery located here helps produce a popular salmon fishery at the confluence of the Kasilof River and Crooked Creek. Kasilof is at Mile 108.8 Sterling Hwy .
