These two pie charts show the percentage of Phosphorus contributed by each source and the percent of the watershed covered by each land use. The 11 land uses categories shown here are groupings of 21 different phosphorus sources indentified.
	Development contributed the highest amount of phosphorus to the lake despite its small land cover. Septic systems contributed the second highest amount of Phosphorus. Both non-shoreline residential areas and septic systems contributed more phosphorus that shoreline residences. However, remember there are three times as many non-shoreline  residences as shoreline ones.
	The third highest contributor of Phosphorus is forests. Although forests contribute a very small amount of phosphorus per acre, they make up over two thirds of the watershed area.
	Roads are the fourth largest source of phosphorus. They are a very problematic source of phosphorus considering their small area. While they are make up less that 1% of the watershed area, they contribute over 13% of the phosphorus.
	The remaining 7 soucres contribute just a third of the phosphorus. Two that are worth mentioning are recreational areas (which include commercial camps and campgrounds) and logged and cleared land. Recreational areas can have an adverse impact because they tend to concentrate larger numbers of people along the shoreline for extended periods of time. Logged and cleared land can potentially add large amounts of phosphorus by promoting erosion.
