Display Name: Surface Waters with Impairments 2020 with Quarter Mile Buffer
Description: <DIV STYLE="text-align:Left;"><DIV><DIV><DIV STYLE="font-size:12pt"><P><SPAN>Quarter mile buffer of watersheds clipped to the state border for assessment unit IDs (AUID) that have one or more impairment related to storm water runoff in the 2016 305(b)/303(d). AUID are nearly synonymous with waterbody IDs (WBIDs) in that WBIDs are continuously updated whereas AUIDs are a version of the features tied to a particular Clean Water Act assessment cycle. AUIDs are the basic unit of record for conducting and reporting water quality assessments to EPA. All assessment units are based on 1:24,000 scale hydrography linked to the National Hydrography Dataset (NHD); the national coverage used by EPA. The 2020 AUIDs were the basis for the delineations in this file.</SPAN></P><P><SPAN /></P><P><SPAN>Watersheds were delineated using a10m DEM that had been burned with the 24k NHHD and catchment walled. After automated delineation, watershed received a visual evaluation for reliability. Each quarter mile buffer on an AUIDs was clipped by the watershed for that AUID to remove any non-contributory areas.</SPAN></P></DIV></DIV></DIV></DIV>
