Name: Chesapeake Fish Passage Prioritization Tool Data

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: Dam data for the Chesapeake Bay watershed. This data was originally compiled in 2017 from multiple state and federal sources and edited by The Nature Conservancy for use in the Chesapeake Fish Passage Prioritization project. These data were "snapped" to a modified (single-flowline, dendritic) version of the high-resolution (1:24,000) National Hydrography Dataset, so that the dam points are geometrically coincident with the stream lines. The data underwent several quality control checks to help ensure that dams are located in the proper location. These include identifying barriers within 100m of another barrier to flag potential duplicates and assessing barriers for similar names using fuzzy string matching. Barriers identified as potential duplicates were manually reviewed against current aerial imagery in ArcGIS Pro. IN the case of duplicates, one barrier was marked as a duplicate and the other retained for use in the analysis. Original Source data (2013).

Personal communication August 17, 2022. • Individual dam updates based on the manual review of barriers by members of the Chesapeake Fish Passage Workgroup via ArcGIS Online. Culvert data is primarily sourced from the North Atlantic Aquatic Connectivity Collaborative (NAACC): https://naacc.org/naacc_data_center_home.cfm These data are based on field surveys of road-stream crossings conducted by trained surveyors, then reviewed and submitted to the NAACC database. Surveyed culverts that are rated as 'Severe' barriers to aquatic connectivity were considered as barriers in the analysis. Additional culvert data were obtained from Maryland DNR as part of the original dam data transfer. These culverts are generally lower in the system and were considered to be barriers to fish passage.
