| NOTE: Ohio EPA summarizes data for the Integrated Report at watershed, large river segment, and Lake Erie shoreline segment scales. Additional details on underlying data observations are available and can be used for more detailed analysis of water resource condition on a more localized, in-depth scale. Much of the information is available in watershed reports available at http://www.epa.state.oh.us/dsw/tmdl/2004IntReport/2004OhioIntegratedReport.htmll. |
