Please note that we are Excluding the direct inputs and sediment release factors for right now to focus on the other inputs.  You can see from this figure that the highest remaining percent contribution of phosphorus in our watershed are atmospheric (POINT), shoreline residential (POINT), and camp roads (POINT), and shoreline septic (POINT)
	Atmospheric input at 17% is from particulate matter in the atmosphere such as from industry and wood stoves that may occur far from the LPN watershed.
	The other factors are based on conditions in our watershed.
	Many of the septic systems around the lake have been recently updated due new development and conversion from seasonal to year round residency.  However, even properly functioning shoreline septic systems still have the potential to contribute large quantities of phosphorus based on their proximity to the lake as we see that it contributes 23% of our phosphorus loading.
	Runoff from camp roads at 15% is also a problem because they are mostly unpaved, located close to the shore, and often lacking proper drainage or crowning.
	Shoreline residential at 12% has to do with increased development and reduction of buffering systems.
	These are the areas that should be continued to be monitored and improved in terms of phosphorus retention.
