The primary flow providers are precipitation and runoff from tributaries such as the Kentucky River and Licking River. Markland Dam is a significant dam on the river that helps regulate the flow downstream. Seasonal trends show that the river typically has higher flow rates in the spring due to snowmelt and spring rains. Interestingly, the Ohio River is known for being one of the most polluted rivers in the United States due to industrial and agricultural runoff. Despite this, it remains an important source of drinking water and recreation for many communities in the region.
