2020 303(d) - 4a lakes

SDE Feature Class Tags
TMDL, 2020 303(d), water, lakes


Summary 

The purpose of this dataset is to provide a cartographic representation of the lakes on the Impaired Waterbodies 303(d) list in Category 4a. Additional information can be found Part IV of the 2020 Integrated Water Quality Monitoring and Assessment Report (305(b)).

Description This data includes lakes 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 lakes from the National Hydrography Dataset (NHD) High Resolution (1:24,000) Waterbody. 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);
