Welcome to the Division of Surface Water

The Division of Surface Water ensures compliance with the federal Clean Water Act and works to increase the number of water bodies that can safely be used for swimming and fishing. We issue permits to regulate wastewater treatment plants, factories and storm water to reduce the impact of pollutants. We develop comprehensive watershed plans aimed at improving polluted streams. We sample streams, lakes and wetlands, including fish, aquatic insects and plants, to determine the health of Ohio’s surface waters.

Integrated Water Quality Monitoring and Assessment Report

Preparation of the 2010 Integrated Report is underway. The report fulfills the State’s reporting obligations under Sections 305(b) and 303(d) of the Federal Clean Water Act. It will indicate the general condition of Ohio’s waters and list those waters that are currently impaired and may require Total Maximum Daily Load (TMDL) development in order to meet water quality standards.
