The Great Amenities

Candlewood Lake Since 1928

Stormwater Runoff

Bacteria Growth at Candlewood

Healthy Toxic

Hypothesis

The health of Candlewood Lake is determined by each municipality’s

regulations to limit negative influences of the lake ecosystem.

Impervious Surfaces

Septic Systems

Soil Erosion

Buffer

PredictionsNew Fairfield and Sherman does not have enough

policies to influence the lake’s health in a positive way.

New Milford has strong policies that would influence the lake in a positive way.

As for Brookfield and Danbury, I knew they had decent policies in place but I was unsure how influential they were.

Temperature and the amount of rainfall will influence the amount of beach closings
