Status and trends in streamflow across the Chesapeake Bay watershed
The Chesapeake Bay is greatly affected by freshwater flows from streams and rivers draining its watershed. Variations in the amount and timing of streamflow can change water temperature, salinity, suspended sediment and contaminants levels, and affect the amount of nutrients in freshwater streams. Additionally freshwater flows affect the amount of in-stream habitat available to freshwater flora and fauna. Metrics characterizing streamflow extremes such as magnitude, frequency and duration of high and low flows are helpful indicators of long-term patterns, shifts in streamflow regimes, and the interpretation of their effects on stream biota. Generalized additive models were used to analyze long term changes in annual metrics of streamflow extrema from water year 1985 through water year 2022. Detailed data preparation information, analytical methods and results are presented and discussed in the associated Scientific Investigative Report (https://doi.org/10.3133/sir20255072).
