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 5 alt. 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 for the listed pollutant pair(s) (Category 5 alt). It consists of a subset of the streams from the National Hydrography Dataset (NHD) High Resolution (1:24,000) Flowline. Category 5 alt is described as follows: Category 5. The waterbody is impaired, or one or more water quality standards may not be attained. Category 5 alt Waters where alternative restoration approaches may be more immediately beneficial or practicable in achieving WQS than pursuing the TMDL approach in the near-term.
