<DIV STYLE="text-align:Left;font-size:12pt"><P><SPAN>The riparian area guidance does not apply to wetlands (or drainage channels excavated within wetlands), or shorelines of ponds, lakes, reservoirs, and marine waters. It also does not apply to ditches or canals excavated for irrigation or drainage, nor management induced channels such as rills and gullies. For this reason, these hydrologic features are not included in this layer.</SPAN></P><P><SPAN /></P><P><SPAN>The buffer width information presented in this map is based on the Visual Surface Water data, and the most recent published flowlines (summer 2022) from the National Hydrography Dataset Plus HR (NHD+ HR). Visible Surface Water data was compiled by the Washington Department of Fish and Wildlife (WDFW) and combined with NHD Area polygons and buffered NHD flowlines so that minimum buffer widths for intensive agriculture (Option 3) could be assigned to the largest-estimated stream size.</SPAN></P><P><SPAN /></P><P><SPAN>Stream flowlines will only draw on the map at certain scales; if you don't see the blue stream lines and orange buffer areas, zoom in further until they display. </SPAN></P></DIV> |
