Status and trends in stream temperature, salinity, flow, hydromorphology, and biological assemblages across the Chesapeake Bay Watershed

August 19, 2025

The Chesapeake Bay watershed is home to over 18.5 million people and continues to experience rapid population growth. With changes in population and land development, understanding current conditions of streams within the watershed (status), and changes in condition over time (trends) is important for assessing stream health. This data release contains the output files for results of status and trend analysis for stream water temperature, salinity, flow, hydromorphology, and biological aquatic community indicators of stream condition in the Chesapeake Bay watershed from the associated Scientific Investigative Report (https://doi.org/10.3133/sir20255072). Data and results for nutrients and suspended sediment (https://doi.org/10.5066/P97IFYES) and toxic contaminants (https://doi.org/10.5066/P9R78SQ6) were released previously.
