PowerPoint Presentation

�Total external load (direct watershed): 410 kg/yr

1.Forest: 107 kg/yr or 25-26% of total P load

2.Shoreline septic tanks: 96 kg/yr or 23%

3.Shoreline development: 56 kg/yr or 14%

� Sediment release contributed the most phosphorus:

328 kg/yr

Total Phosphorus Loading Results


	Talk about the 3 largest contributors
	Forest: small P load, but large area

	Shoreline septic: shoreline septic systems have more impact on the lake because of proximity to the water
	Contribution was high due to houses close to shore and possibility for leakage and overflow from flooding

	Shoreline development: increases amount of impervious surface, increases erosion and amount of sediment and other P into lake
