Tributaries

Most of the Ohio River Basin is drained by tributaries; less than five percent of the basin runoff drains directly into the main stem. The runoff characteristics of the tributaries therefore determine the quantity of flow in the Ohio at any time. The Corps of Engineers operates numerous reservoirs in the Ohio River Basin. Most were built for flood control purposes; many are also used to provide flow augmentation at critical periods. This has resulted in an increase in the quantity of flow that could otherwise be expected in the dry weather months.
