State of Ohio Environmental Protection Agency January 2008 Leading Creek Watershed TMDL Report What are the essential facts? • Ohio EPA and other groups studied the Leading Creek watershed and found water quality problems at several of the locations measured. • The watershed can make progress towards restoration with practical, economical actions. • Improving the streams depends on the participation of the watershed’s residents. What is the significance of this report? The Leading Creek Watershed TMDL Report is a tool that includes local ideas from the endorsed watershed management plan and the improvement plan to help improve and maintain water quality and habitat in the watershed. What is a watershed? A watershed is the land area from which surface runoff drains into a specific body of water. Where is the Leading Creek Overall, the land use in the The Leading Creek watershed watershed?

The ecoregion is characterized by extensively forested rolling hills with small pockets of dairy, livestock, farming, and residential development. Its underlying bedrock primarily consists of sandstones, shales, limestones, and coal. An estimated 7,000 to 7,500 citizens reside in the Leading Creek watershed. The largest community entirely within the watershed is Rutland, which has a population of approximately 400 people. The communities of Albany and Middleport are located in the headwaters and at the mouth, respectively. Leading Creek about 10 miles upstream from its mouth.

In 1993, an emergency discharge of contaminated water from the Meigs #31 Mine destroyed habitat and caused a large fish kill in Parker Run and downstream into segments of Leading Creek. This report builds on several previous studies of the Leading Creek watershed, including the Watershed Management Plan, the Acid Mine Drainage Abatement and Treatment (AMDAT) Plan, and the Leading Creek Improvement Plan. Data collected by the Leading Creek Improvement Committee (2003-2006) and for the Leading Creek Improvement Plan (1996, 1997) were used for analyses in the TMDL report. How does Ohio EPA measure water quality? Ohio is one of the few states that measures the health of its streams by examining the number and types of fish and aquatic insects in the water. An abundance of fish and insects that tolerate pollution is an indicator of an What is the condition of the unhealthy stream. A large number Leading Creek watershed?

How will water quality get better? The Leading Creek watershed is included on Ohio’s list of impaired waters. Under the Clean Water Act, a cleanup plan is required for each impaired watershed. This cleanup plan, known as a Total Maximum Daily Load (TMDL) report, calculates the maximum amount of pollutants a water body can receive and still meet standards (goals). The TMDL report specifies how much pollution must be reduced from various sources and recommends specific actions to achieve these reductions. The TMDL report provides specific numeric goals for reducing pollutants, including pathogens, phosphorus, sediment, and for improving habitat. Ohio EPA can address some of the Leading Creek problems directly through regulatory actions, such as permits for dischargers. Other actions, Measuring water quality in a tributary to Leading Creek.
