Appendix E is a list of public nonpoint source impacted lakes and their acreage. Appendix F contains information on how to order reports and obtain helpful documents. A map of Ohio EPA districts and district office contact information is provided on the back cover. Streams NPS information for streams can be obtained over the internet or by contacting Ohio EPA district offices. Streams within Hydrologic Groups are divided into segments.
Segments are usually portions of the stream extending from one tributary confluence to another.
NPS assessment information is provided for stream segments and includes an evaluation of how attainment is affected by NPS pollution. Impaired streams are those failing to attain their aquatic life use designation. Impacted streams are affected by nonpoint source pollution, but it has not been determined whether or not they are attaining their aquatic life use designation. Threatened streams are presently attaining their aquatic life use designation, but the possibility exists for future impact from NPS pollution. An example of the type of information available for a stream segment is shown in Table 1.
