Map: Chesapeake Bay watershed 5 year short-term phosphorus yields 2007 - 2011

Average yields for total phosphorus (TP) were estimated for the last five years at 65 sites and classified into thirds as high, medium, and low. While the distribution was spatially variable, there were some general patterns in location. Generally, higher yields for TP are dominant in the middle of the watershed, areas that also coincide with large urban and agricultural land uses. The lowest yields are generally in the western areas of the Bay watershed, an area dominated by forests.
