Cut by the curve of the Okanogan River, is the largest town in the north-central part of the State. The compact and solidly built business district fronts on the main highway. Across the river were warehouse-lined railroad tracks and old straggling streets.
When the town of Omak was platted in 1907 the name of the post office which had previously been Epley was changed to Omak. The name is from the Native American word Omache, meaning good medicine or plenty, which was given to a nearby creek and lake. This was altered to Omak at the suggestion of postal authorities, who preferred brevity to history.
The Omak Stampede, a two-day festival and rodeo, remains a popular event, and is held the second weekend in August.
