Developing County Level Time Series of Nutrient Inventories and Trend Maps

Presentation highlighting updates to the Chesapeake Bay Inventory effort to the Modeling Workgroup of the Chesapeake Bay Program.

Impact/Purpose

Provide an update on the status of the county level fact sheets and efforts to develop bay-wide nutrient inventories across the Chesapeake Bay and efforts to relate shifts in the inventory to observed changes in water quality. Overview of major trends for likely sources of point and non-point source pollution will be presented at the county level as well as preliminary statistical results on state level effects on these trends. This inventory and associated County Fact Sheets demonstrate the power of maps and pictures in communicating largely positive progress in the Chesapeake watershed and Bay clean up and satisfy stakeholder and decision makers’ desire to see where they stand, by county in this case, relative to other counties and regions.
