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
