The Conhocton River, the original Native American name for "log floating in the water," meanders through the countryside, and off Interstate 390, in the Southern Tier. The river is a tributary of the Chemung River. It is a gathering place for fly-fishermen from all over the country. Actually, it has been a best kept secret of locals until more recently when the word has gotten out.
