Summary
This data release links habitat assessment sites to both the NHDPlus Version 2 and NHDPlus High Resolution Region 02 networks using the hydrolink methodology. Linked habitat sites are those compiled by the Interstate Commission on the Potomac River Basin (ICPRB) during creation of the Chesapeake Bay Basin-wide Index of Biotic Integrity (Chessie BIBI) for benthic macroinvertebrates (https://datahub.chesapeakebay.net/LivingResources). The data set contains a unique sample identifier created by ICPRB, survey program, coordinates of sample, linked V2 COMID and HR Permanent Identifier, and information regarding uncertainty in the attribution. We strongly caution the use of sampling points with attribution uncertainty to avoid spurious attribution [...]

Purpose
Rapid habitat assessment sampling data points were assigned to the NHDPlus Version 2 and NHDPlus High Resolution Region 02 (V2 and HR) catchments to enhance the spatial accuracy of various geospatial landscape data that would be summarized to NHD catchments and attributed to represent the local and upstream landscape influencing the sampling data. These data links are of better quality than a naive intersection of sampling points and NHD catchments via coordinates, since all points with multiple potential flowline matches were visually checked for accuracy using topographic maps and data provider ancillary site information. This process limits linking errors, especially erroneous linking of points representing flowlines that are not present in the NHD network, or points with low resolution spatial data that can be corrected by consulting data provider notes. This vetted linking makes the data potentially useful for a variety of geomorphology and landscape ecology approaches utilizing the V2 and HR catchments and/or networks.
