In 1786 the Russian leader of the Lebedef-Lastochkin Company, Kolomin, built a stockade at the location of Kasilof - it bore the name Saint George, probably after the name of one of the ships of the company. An agricultural settlement of Dena'ina people grew up around the stockade. The area became known as Kasilof after the Kasilof River in the 1800s. A partial excavation of the area in 1937 found 31 well-preserved houses from the settlement. As of 2011[update] most residents are non-Native.
