The Chagrin River is located in Northeast Ohio, flowing through Cuyahoga, Geauga, and Lake counties. It is approximately 50 miles long and has a watershed area of 285 square miles. The river was important to Native American tribes and later European settlers, who used it for transportation and industry. Today, the river is heavily managed for flood control and water supply, with several reservoirs and dams along its length, including the Upper and Lower Chagrin River Reservoirs. The river also provides recreational opportunities, including fishing, kayaking, and hiking along its banks. Some agricultural uses include irrigation for crops and livestock watering. However, pollution from urban and agricultural runoff is a significant issue, and efforts are underway to improve water quality and protect the river's ecosystem.
