Lake Phosphorus Levels after period of rain (above) and after dry period (below):

Notice: Each pixel is 30 square meters (roughly 100ft x 100ft).


  • Candlewood Lake as little phosphorus (P) in the main body after a large rain event.
  • P levels are high at the lake borders.
  • P levels are high for the Housatonic River feeding Lake Lillinonah even during a high flow wet period.


  • Candlewood Lake has high P levels after a prolonged period of no rain.
  • With no storm waters in a dry period, water infiltration to Candlewood Lake is dominated by septic effluent.
  • P can also be diffusing in to the water from P laden sediment. Which P source dominates?
