Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The catchment and catchment routing data in NHDv2.1 products are utilized to understand flow to the Chesapeake Bay and to assess water quality impacts to the Bay. The areas of land captured in the catchments representing the watershed are outdated due to man-made storm drains and pumping practices. Additionally, the catchments used to represent the Chesapeake Bay Watershed vary depending on how the catchments were selected. This layer ensures consistent representation of the watershed. The modified Chesapeake Bay Watershed boundary is equivalent to the boundary of the modified catchments. </SPAN></P></DIV></DIV></DIV>
