ßSeasonal versus year round
As I mentioned, residential land is a potential nutrient contributor to lake water.  Nutrients may be added through the use of lawn and garden fertilizers and pesticides, house hold wastes, and septic systems.  Residential areas also increase run from impervious surfaces such as driveways and rooftops.

CEAT conducted house count where the number of shoreline and non-shoreline homes in the watersheds was determine.  We used 200 ft as the cut off.  Homes within 200 ft of the shore were considered shoreline, all others, non-shoreline.
At the same time, we also determined the number of seasonal versus year round homes by examining particular features such as  the foundation of the house, the presence of a chimney, and other evidence of winterization.

It is important to note that shoreline and year round homes often contribute higher levels of nutrients and pollutants to to close proximity to the shore (shoreline) and increased amount of use (year round).
Pollutants generated close to a water body have less time to be absorbed into the soil and vegetation before entering the lake than pollutants generated further away from the water.
