About the Ashtabula River AOC

map showing the state approved boundary of the Ashtabula River AOCAshtabula River AOC Boundary MapThe Ashtabula River was designated as a Great Lakes Area of Concern under the 1987 Great Lakes Water Quality Agreement.  Of the six environmental impairments that were originally present, three remain. All management actions at the AOC have been completed. EPA will support monitoring and evaluation to determine when environmental conditions have been restored so that the AOC can be delisted.

AOCs Boundaries

The Ashtabula River AOC lies in extreme northeast Ohio. The Ashtabula River flows into Lake Erie's central basin at the city of Ashtabula. The city of Ashtabula is the only significant urban center in the watershed. The rest of the drainage basin is located in predominantly rural and agricultural areas. Major tributaries include Fields Brook and Strong Brook.
