Stream ecosystems worldwide face ongoing degradation, underscoring the urgent need for conservation and restoration. Regional analyses of stream condition have been limited by sparse spatial and temporal data, particularly at long time scales. To address this gap, we used observed data to predict annual biological condition for 360,893 small, nontidal stream reaches in the Chesapeake Bay...

39 Years of Stream Conditions Show Widespread Biological Changes Across the Chesapeake Bay Watershed
USGS scientists predicted stream biological conditions across the Chesapeake Bay watershed from 1985 through 2023, revealing widespread changes but only a ~1% increase in stream length classified as improved. These predicted improvements fell short of the Chesapeake Bay Program’s goal of improving the health of 10% of streams by 2025.
