Oatka Creek

Oatka Creek is the third longest tributary of the Genesee River, located entirely in the Western New York region of the U.S. state of New York. From southern Wyoming County, it flows 58 miles to the Genesee near Scottsville, draining an area of 215 square miles that includes all or part of 23 towns and villages in Wyoming, Genesee, Livingston and Monroe counties as well. Its name means "leaving the highlands" or "approaching an opening" in Seneca.

Like its parent stream it originated during the end of the last Ice Age, as glacial impact on the upper Allegheny Plateau created a rolling landscape streams could gradually erode through, The Oatka carved a deep groove known today as the Oatka Valley, where the upper creek's two major settlements would be established. Native Americans of the Seneca nation established a few settlements along it where clearings arose in the forest. The Revolutionary War's Sullivan Expedition, brought the valley's fertile soil to the attention of the emerging nation, and the region was opened for settlement shortly after the war.
