Lake phycocyanin levels after period of rain (above) and after dry period (below):

Phycocyanins are found in Cyanobacteria (previously called blue-green algae).

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

Above:

  • Candlewood Lake as sparse phycocyanin levels in the main body after a large rain event. 
  • Phycocyanin levels are low at the borders and higher in the center of Candlewood Lake. 
  • Phycocyanin levels arel ow for the Housatonic River feeding Lake Lillinonah following a high flow wet period. 

Below:

  • Candlewood Lake has elevated Phycocyanin 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. 
  • Lake Lillinonah as low levels of phycocyanin (blue-green algae) in the dry period, problably because it has stream flow, unlike Candlewood Lake that has only septic flow entering the lake.
