Description

As part of an annual evaluation of water-quality conditions by the Chesapeake Bay Program, water-quality and streamflow data from 32 sites in nontidal parts of the Chesapeake Bay watershed were analyzed to document annual nutrient and sediment trends for 1985 through 2004. The report also presents the results of continued evaluation of techniques to describe changes in streamflow, concentrations, and loads in the Chesapeake Bay watershed. In addition, results from all current evaluations for all sites are presented in the appendixes at the end of the report.
