Description: This is a detail of a map from the Southwest Florida Watershed Management District or SWFWMD of the Hillsborough River watershed non-point source loading potential showing total phosphorus only, created on November 2, 1999. Non-point source pollution is not from industrial and sewage treatment plants, but comes from many diffuse sources or multiple small sources spread out over a wide area. This map shows the potential for this with phosphorus. The increases are shown in percentages from least (blue) to greatest (red). It also shows the Watershed Management boundary shown by the thick black line.
