Pigeon Creek. Pigeon Creek is a tributary of the Ohio River. It runs approximately 47.5 miles (76.4 km) from its eastern source in rural Gibson County near Princeton and its western source near Owensville. The forks merge southeast of Fort Branch, and from there it heads southeast into Warrick County near Lynnville, from where it heads south. The larger creek then turns west crossing into Vanderburgh County under Interstate 69. The creek has a few more tributaries join as it first heads west through Evansville's East and North Sides then south through Downtown Evansville, where it empties into the Ohio River.
