TMDL, not-impaired, 2018 303(d), water
The purpose of this dataset is to provide a cartographic representation of the streams in Category 1b as a result of the 2018 assessment of the State’s waters. 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 meeting their water quality standards and designated uses, and have completed TMDLs (Total Maximum Daily Loads) in place for a previously impaired pollutant pair(s) (Category 1b). It consists of a subset of the streams from the National Hydrography Dataset (NHD) High Resolution (1:24,000) Flowline. Category 1b is described as follows: Category 1. Attains all water quality standards for all designated uses; categorized by existence of a TMDL or not for one or more constituents: 1b. Attaining all water quality standards for all designated uses; however, a TMDL remains in place for one or more constituents
