impaired waters, 2018 303(d), water
The purpose of this dataset is to provide a cartographic representation of the streams on the Impaired Waterbodies 303(d) list in Category 4b. Additional information can be found Part IV of the 2018 Integrated Water Quality Monitoring and Assessment Report (305(b)).
This data includes streams of Arkansas that have been assessed as Impaired Waterbodies and have alternative plans in place for the listed pollutant pair(s) (Category 4b). It consists of a subset of the streams from the National Hydrography Dataset (NHD) High Resolution (1:24,000) Flowline. Category 4b 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: Category 4b. Other pollution control requirements are expected to result in the attainment of the water quality standard
