The Olentangy River flows 88.5 miles from its headwaters in Crawford and Richland County through Marion and Morrow County into the City of Delaware and ending in Franklin County at its confluence with the Scioto River.
The Olentangy River has a drainage area of 536 square miles. Twenty-two miles of the Olentangy were designated a state Scenic River by the Ohio Department of Natural Resources in 1973.
The designation runs from the Delaware Dam, north of the City, to the old Wilson Bridge Road in Worthington.
Everyone lives in a watershed and the City of Delaware is located in the Olentangy River watershed. A watershed is an area of land that directs surface water and ground water towards a single body of water. A ridge separates one watershed from another and will drain the water in different directions.
Each watershed can be broken down into subwatersheds or increased into larger watersheds. If the Olentangy River watershed was broken into smaller subwatersheds, some residents in the City of Delaware would live in the Delaware Run subwatershed, while others would live in the Sugar Run subwatershed. There are several other small waterways connecting to the Olentangy River that would be additional subwatersheds.
If the Olentangy River watershed was increased into larger watersheds, the Delaware City residents could say they live in the Scioto River watershed. Since the Olentangy drains into the Scioto River this would be a true statement. This also makes our watershed the Ohio River, Mississippi River, and Gulf of Mexico.
