Over the past 10 years, sediment concentration trends show mixed responses among the monitoring sites with the majority of results being not significant, 5 sites indicate improving conditions while 6 sites indicate degrading conditions. The trend results indicate that in some locations, management actions, such as erosion and runoff controls may have contributed to reducing sediment concentrations in streams. The short-term flow-adjusted trends and yields indicator is calculated, and results and maps are published annually by the U.S. Geological Survey as part of a larger effort to determine loads and trends in nutrient and sediment concentrations and streamflow in the Chesapeake Bay watershed.
