Maumee Watershed Nutrient Total Maximum Daily Load (TMDL) Project

Ohio EPA's first outreach module on the Maumee Watershed Nutrient TMDL Project is now available for viewing. This module provides background on the overall TMDL process and this project.

This is the first module in a series of three modules Ohio EPA is developing for the Maumee Watershed Nutrient TMDL Project. The second module will provide details on the Maumee Watershed Nutrient TMDL project to date and the third module will highlight ongoing implementation activities to reduce nutrients in the watershed.

Division of Surface Water Mission Statement

The division's mission is to protect, enhance and restore all waters of the state for the health, safety and welfare of present and future generations. We accomplish this mission by monitoring the aquatic environment, permitting, enforcing environmental laws, using and refining scientifically sound methods and regulations, planning, coordinating, educating, providing technical assistance and encouraging pollution prevention practices.

Who We Are

Ohio is a water-rich state with more than 25,000 miles of streams and rivers, a 451-mile border on the Ohio River, more than 5,000 lakes, ponds, and reservoirs (>1 acre), and 236 miles of Lake Erie shoreline. Ohio has 10 scenic rivers comprising more than 629 river miles, the fourth largest total of any state in the nation.

The Division of Surface Water is responsible for restoring and maintaining the quality of Ohio's rivers and streams. The goal of Ohio's surface water program -- restoration and maintenance of Ohio's water resources -- reflects the national water quality objective in the Federal Clean Water Act (CWA), which is "to restore and maintain the chemical, physical, and biological integrity of the Nation's waters. The CWA objective is often referred to as the "fishable/swimmable goal."

The fishable/swimmable goal is different from the popular idea of clean water as being water that is chemically pure. Instead, fishable/swimmable waters are resources that support stable, balanced populations of aquatic organisms which are ecologically "healthy," and provide safe water to the people of Ohio for public and industrial water supplies and recreation.

The Division of Surface Water has a full time staff of approximately 240 located in Columbus and the five district offices. The division also employs approximately 50 interns during the summer to assist with biological and chemical water quality surveys. Funding for the division is comprised of federal and state monies as well as annual discharge fees.

The Tools We Use

The Division of Surface Water utilizes many tools in working to achieve its goals:

• Water Quality Programs — these programs support the Clean Water Act’s “fishable, swimmable” goals for all surface waters in Ohio. These programs assess the quality of the surface waters, set standards for protection of the waters and establish plans to bring impaired waters back into attainment with water quality goals.
  • Inland Lakes Program — contains information on water quality monitoring of Ohio's inland lakes.
  • Lake Erie Programs — remedial action and management plans for restoring and maintaining beneficial uses of Lake Erie.
  • Nonpoint Source, Section 319 & Surface Water Improvement Fund (SWIF) Programs — promote implementation of land use practices to reduce nonpoint source (runoff) pollution.
  • Total Maximum Daily Load (TMDL) Program — focuses on identifying and restoring impaired or threatened water bodies.
  • Water Quality Monitoring Program — conducts statewide biological and water quality surveys to support water quality management activities.
  • Water Quality Standards Program — contains the current standards and guidelines for meeting Ohio's water quality goals.
• Credible Data (Volunteer Monitoring) Program — classifies surface water monitoring performed by watershed groups, state agencies, schools, local volunteers and other organizations.
• Enforcement Program — works with the regulated community to insure compliance with water quality standards.
• GIS & Interactive Maps — view and download geographic information related to Ohio's surface waters.
• Permits Programs — The Division of Surface Water's permits program contains permit regulations and procedures for 
  • biosolids, concentrated animal feeding operations, municipal and industrial wastewater (individual or general),  pretreatment and storm water individual and general permits, construction permit to install permits and section 401 water quality certification and isolated wetland permits.
• Section 208 Plans & State Water Quality Management Plan Program — contains information in Areawide Waste Treatment Management Plans prepared pursuant to Section 208 of the Clean Water Act and the State Water Quality Management Plan.
• Sport Fish Consumption Advisory Program — provides information on fish consumption advisories issued by the Ohio Department of Health for sport fish caught in Ohio waters.
