Description: National Hydrography Dataset NHDFlowline designated as Exceptional Value or High Quality clipped to Lancaster County. This layer is a spatial representation of designated water uses defined in Title 25 Environmental Protection, Department of Environmental Protection, Chapter 93, Water Quality Standards. The Pennsylvania Code just cited provides a list of all streams or watersheds (basins) in the state along with their associated designated water uses. This GIS layer displays these uses spatially on an interactive stream map. Public users can drill down to locations on the map to view and map the designated uses of the water bodies of interest. The layer can also be used in conjunction with other spatially referenced data for spatial analyses. 2017 Pennsylvania Department of Environmental Protection Downloadable from: http://www.pasda.psu.edu/uci/DataSummary.aspx?dataset=1098

Description: Integrated List Non-Attaining Streams that are non-attaining for aquatic life designation, clipped to Lancaster County. This layer shows only non-attaining segments of the Integrated List. The Streams Integrated List represents stream assessments in an integrated format for the Clean Water Act Section 305(b) reporting and Section 303(d) listing. Streams are bodies of flowing surface water that collectively form a network that drains a catchment or basin. PA DEP protects 4 stream water uses: aquatic life, fish consumption, potable water supply, and recreation. The 305(b) layers represents stream segments that have been evaluated for attainment of those uses. If a stream segment is not attaining any one of its 4 uses, it is considered impaired. · Aquatic Life use attainment - The integrity reflected in any component of the biological community. (i.e. fish or fish food organisms). 2017 Pennsylvania Department of Environmental Protection.

Description: National Hydrography Dataset Plus High Resolution Flowlines, clipped to HUCs that intersect with Lancaster County. The NHDPlus HR is a national, geospatial model of the flow of water across the landscape and through the stream network. The NHDPlus HR is built using the National Hydrography Dataset High Resolution data at 1:24,000 scale or better, the 1/3 arc-second (10 meter ground spacing) 3D Elevation Program data, and the nationally complete Watershed Boundary Dataset.

Description: Hydrography Centerlines. This dataset contains lines representing all perennial streams and the centerlines of rivers wider than 10 feet. The features are pointed in the direction of streamflow. Features were updated using NGA and USGS 30 centimeter aerial photos flown from March 26th through April 3rd, 2012 that encompass the entire County. Red-Green-Blue and Color Infrared were both used to capture, modify, and validate new and changed features. 2014 Lancaster County.
