Ohio Drainage Law: A Brief Overview

Lake County Soil & Water Conservation District receives many questions regarding drainage concerns between neighboring properties. The information below provides a general overview of Ohio drainage law and common drainage-related concerns.

Ohio follows the “reasonable use” doctrine for drainage and surface water. This means landowners may make reasonable improvements to their property, even if those improvements affect drainage patterns. However, those changes should not unreasonably harm neighboring properties.

In general:

• Landowners may make reasonable use of their property, including drainage improvements.
• Water naturally flows from higher elevations to lower elevations, and lower properties are generally expected to accept this natural flow.
• Landowners should not unreasonably increase the volume, rate, or concentration of water flowing onto neighboring properties.
• Drainage changes that cause flooding, erosion, or other damages may result in liability for the responsible party.
• Most drainage disputes between neighboring landowners are civil matters and are typically resolved through cooperation, legal counsel, or the courts.
• Lake County Soil & Water Conservation District can provide technical assistance and information but does not have the authority to resolve private drainage disputes or enforce drainage laws.
