Description: The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data for each decennial census. The Census Bureau delineates ZCTA boundaries for the United States, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands once each decade following the decennial census. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery. The Census Bureau uses tabulation blocks as the basis for defining each ZCTA. Tabulation blocks are assigned to a ZCTA based on the most frequently occurring ZIP Code for the addresses contained within that block. The most frequently occurring ZIP Code also becomes the five-digit numeric code of the ZCTA. These codes may contain leading zeros. Blocks that do not contain addresses but are surrounded by a single ZCTA (enclaves) are assigned to the surrounding ZCTA. Because the Census Bureau only uses the most frequently occurring ZIP Code to assign blocks, a ZCTA may not exist for every USPS ZIP Code. Some ZIP Codes may not have a matching ZCTA because too few addresses were associated with the specific ZIP Code or the ZIP Code was not the most frequently occurring ZIP Code within any of the blocks where it exists. The ZCTA boundaries in this release are those delineated following the 2020 Census.Dataset only includes zip codes intersecting the Susquehanna River Basin.
Description: 118th Congressional Districts for the New York, Pennsylvania, and Maryland portions of the Susquehanna River Basin. Attached to these are the respective congressmen/women for each district following the 2022 election.
Description: Districts for the New York Assembly, Pennsylvania House of Representatives, and Maryland House of Delegates in the Susquehanna River Basin.
Description: Polygon shapefile that includes the subbasins of the Susquehanna River Basin (2006 boundary). The 6 subbasins include the Upper Susquehanna, Chemung, Middle Susquehanna, West Branch Susquehanna, Juniata, and Lower Susquehanna. This file was created by dissolving the wshed24K dataset into the 6 major subbasins. The boundary between the Upper Susq. and Chemung Subbasins was updated to match the SRBC delineated subbasin line that exists on 1:24,000 scale USGS topographic maps.

Description: This polygon feature class depicts Environmental Justice (EJ) Areas within the Susquehanna River Basin. EJ areas are based on US Census Bureau block groups and are identified by various indicators such as high ethnic populations, poverty areas, and other environmental factors. Each state has specific criteria for determining EJ Areas:Pennsylvania - PennEnviroScreen provides an annually updated snapshot of undue environmental burden on vulnerable communities. This dataset is the result of a model which combines Pollution Burden and Population Characteristics data in order to identify Environmental Justice (EJ) Areas in accordance with the EJ Policy and is based upon the US Census Bureau's Census Block Group Delineations. New York - Poverty rate of at least 22.82% and minority population of at least 26.28% (rural)/ 52.42% (urban) (Source: 2014-2018 5-Year ACS)Maryland - Provides a geodatabase on the MDE EJ Screening Tool interactive web map - https://mdewin64.mde.state.md.us/EJ/. MDE uses four indicators to screen locations and communities based on census and health data: 1) Pollution burden exposure, 2) Pollution burden environmental effect, 3) Sensitive populations, and 4) Socioeconomic/Demographic indicators. The definition of an overburdened community was used to calculate pollution burden exposure, pollution burden environmental effects, and sensitive populations. The definition of an underserved community was used to calculate socioeconomic/demographic factors. The Final EJ score needs to be above the 75th percemtile statewide to be an EJ area.
Description: Polygon shapefile that includes the major watersheds of the Susquehanna River Basin (2006 boundary). This file was created by dissolving the wshed24K dataset into the major watersheds. The groupings were defined by the needs of the Susquehanna River Basin Commission (SRBC) and represent the SRBC's interpretation of major watersheds in the Susquehanna River Basin. This file was created to work in tandem with wshed24k.shp, subbasin.shp, and srb.shp. This dataset does not match the Hydrologic Unit Code (HUC) 11 digit watersheds.
Description: This shapefile has been edited to match the Susquehanna River Basin boundary delineation. The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" “Standard” (http://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the Susquehanna River Basin. At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.

Description: Polygon shapefile that includes approximately 1:24,000 scale watersheds in the Susquehanna River Basin (2006 boundary). This file was created by merging three small watershed datasets; (1) Smallsheds from the Pennsylvania Department of Environmental Protection (PADEP); (2) Maryland Hydrologic Unit Code (HUC) 14 digit watersheds; (3) 1:24,000 scale watersheds from the United States Geologic Survey (USGS). Pennsylvania watersheds are delineated at 1:24,00 while New York and Maryland watersheds are delinated mostly at 1:24,000 but some were delineated at larger or smaller scale. Additionally, the boundary between the Upper Susq. and Chemung Subbasins was updated to match the SRBC delineated subbasin line that exists on 1:24,000 scale USGS topographic maps.
Description: Polygon shapefile that includes state parks in the Susquehanna River Basin. State parks boundaries were obtained from New York State Office of Parks, Recreation and Historic Preservation (OPRHP), the Pennsylvania Department of Conservation and Natural Resources (PA DCNR), and the Maryland Department of Natural Resources (MDDNR). These files were merged together and clipped to the Susquehanna River Basin.
Description: Polygon shapefile of state forest lands in the Susquehanna River Basin. These areas are the Maryland, New York, and Pennsylvania state forests. The Maryland Department of Natural Resources (MDDNR), the New York State Department of Environmental Conservation (NYS DEC) and the Pennsylvania Department of Conservation and Natural Resources (PA DCNR) provided shapefiles of state forest boundaries to the Susquehanna River Basin Commission. These shapefiles were merged together and clipped to the Susquehanna River Basin.
Description: Defines the individual boundaries of the Pennsylvania State Game Lands for the Management of public resources. This data began as digitized paper maps and is continually being updated via ground truthing by field staff using medium grade GPS units and, as time and resources allow, Survey crews using professional survey grade devices.
Description: This is a polygon coverage of Physiographic Divisions of the Susquehanna River Basin (2006 boundary). It was automated from Fenneman's 1:7,000,000-scale map, "Physical Divisions of the United States," which is based on eight major divisions, 25 provinces, and 86 sections representing distinctive areas having common topography, rock types and structure, and geologic and geomorphic history.
Description: Polygon shapefile depicting geology by rock type, hydrostratigraphic terrain and lithology for the entire Susquehanna River Basin (2006 boundary). It represents the merging of three state (NY, PA, MD) bedrock geology spatial datasets in order to provide basic rock types of the Susquehanna River Basin. The dominant formation lithology that appears in the attribute table were grouped into 19 general rock types, such as sandstone, shale, schist, limestone, dolomite, etc. These rock types are also categorized by hydrostratigraphic terrain. The hydrostratigraphic terrain helps to identify the way in which water flows over or through these rocks.

Description: Polygon shapefile that represents groundwater stresses areas caused by diabase rocks. Diabase is a massive rock that is very difficult to break through and thus areas where it is present has the potential for water shortages. This dataset is not loosely defined as it is based on underlying geology. This dataset works in tandem with Stres_GW.shp. The polygons from the two shapefiles overlap in some places and thus were not merged in an attempt to keep original polygons of both layers present.
