Author: USGS

Date created: Jan 02, 2014

Long Term Trend: Forty-four percent of long-term stream monitoring sites in the Chesapeake Bay Watershed show little change in flow-adjusted concentrations of sediment. The remaining sites were evenly split between improving and degrading conditions. Between 1985 and 2012: - 8 out of 29 sites show improving flow-adjusted trends for sediment concentrations, - 8 sites show degrading trends, and - 13 sites show small changes that are not statistically significant.
