2016 Impaired Lakes 303 d list in Category 4a
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 2016 Integrated Water Quality Monitoring and Assessment Report (305(b)).
This data includes lakes of Arkansas that have been designated 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 Water Hydrography Tiger 2005V1. Category 4 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);
4b. Other pollution control requirements are expected to result in the attainment of the water quality standard; or
4c. Non-support of the water quality standard is not caused by a pollutant.
