Background
Section 305(b) of the Clean Water Act requires states to produce "Water Quality Inventories" that assess progress in achieving the objectives of the Act. In 1990, Ohio changed the title of the report from "Water Quality Inventory" to "Water Resource Inventory". The change reflects an ecosystems emphasis rather than reliance on water chemistry alone. The effects of human activity on aquatic ecosystems are broad, and extend beyond water chemistry to include physical and biological impacts. While chemical water quality remains an important component, it is necessary to consider additional impacts if we are truly interested in achieving the goals of the Clean Water Act by protecting and rehabilitating aquatic resources.
The intent is for the 305(b) report to be a routine check on the progress that states are making toward achieving the goals of the Clean Water Act. These reports focus on examining water resource quality over time and examining the effectiveness of water quality management programs.
Graphics illustrating the status and trends in aquatic life use attainment are available on the Aquatic Life Use Attainment Goal page.

1998 Ohio Water Resources Inventory
The 1998 305(b) report is an addendum to the 1996 report that provides an update (adds 1995 and 1996 water year data) to the aquatic life statistics reported in the 1996 document. The 1996 report should still be used for its in-depth discussion of the status and trends in water quality in Ohio and a summary of the various water quality management programs areas. The three fact sheets listed here summarize the most current water quality status, a forecast analysis, and the causes and sources of aquatic life impairment in Ohio. The 1998 appendix document provides stream reach summaries completed (i.e., 1995 and 1996 water years) since the 1996 report.
