Long Term Flow-Adjusted Trends in Sediment, 1985-2013

Date created: Jan 07, 2015

One-third of the monitoring sites in the Chesapeake Bay watershed show improving long-term flow-adjusted trends in suspended sediment concentrations. Between 1985 and 2013: three out of nine sites—including the Choptank, Patuxent and Potomac rivers—have shown improving trends for sediment concentrations. One site—the Pamunkey River—has shown degrading trends. Five sites—including the Appomattox, James, Mattaponi, Rappahannock and Susquehanna rivers—have shown minor changes that are not statistically significant.
