These updates include DEQ’s Base Water Layer derived from the High Resolution National Hydrology Dataset, DEQ Permitted Facilities, DEQ Permitted Sites as well as updates to all categories of Impaired Waterbodies throughout the State of Arkansas based on the 2018 Integrated Water Quality Monitoring and Assessment Report 305(b).
