ItemDescription
CAT4A_STREAMS_DEQ_2022
The purpose of this dataset is to provide a cartographic representation of the streams on the 2022 Impaired Waterbodies 303(d) list in Category 4a. Additional information can be found Part IV of the 2022 Integrated Water Quality Monitoring and Assessment Report (305(b)).
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This data includes streams of Arkansas that have been assessed as Impaired Waterbodies and have completed TMDLs (Total Maximum Daily Loads) for the listed pollutant pair(s) (Category 4a). It consists of a subset of the streams from the National Hydrography Dataset (NHD) High Resolution (1:24,000) Flowline. Category 4a is described as follows: Category 4. Water quality standards are not attained for one or more designated uses but the development of a TMDL is not required because: 4a. A TMDL has been completed for the listed parameter(s)</SPAN></P></DIV></DIV></DIV>
