Water Quality Monitoring &

Citizen science Programs

Stream Monitoring 

We routinely collect water samples from the six main tributaries that supply over 60% of the water flowing into the lake.  The water samples are analyzed by the Community Science Institute (SCI), a NYS certified laboratory and the results are made public on our website. 


Lake Monitoring

In partnership with the NYS DEC and NYS Federation of Lakes Associations, we participate in the Citizen Statewide Lake Assessment Program (CSLAP) to evaluate both deep and shallow lake locations for key water quality indices throughout the year. 


Shoreline Monitoring for

Cyanobacteria (HABs)

Working in partnership with the Finger Lakes Institute (FLI) and the NYS DEC, our 100+ team of volunteers monitor over 56 miles of shoreline to locate Cyanobacteria (Harmful Algal)  blooms, which can be a health threat for humans and animals.  Regular notifications are sent out to the public to keep everyone aware and safe. 


Nutrient Pollution is a Problem

Nutrient pollution is one of America’s most widespread, costly and challenging environmental problems, and is caused by excess nitrogen and phosphorus in the air and water. Excessive nitrogen and phosphorus that washes into water bodies and is released into the air are often the direct result of human activities. The primary sources of nutrient pollution are:

      • Agriculture: Animal manure, excess fertilizer applied to crops and fields, and soil erosion make agriculture one of the largest sources of nitrogen and phosphorus pollution in the country.
      • Stormwater: When precipitation falls on our cities and towns, it runs across hard surfaces – like rooftops, sidewalks and roads – and carries pollutants, including nitrogen and phosphorus, into local waterways.
      • Wastewater: Our sewer and septic systems are responsible for treating large quantities of waste, and these systems do not always operate properly or remove enough nitrogen and phosphorus before discharging into waterways.
      • In and Around the Home: Fertilizers, yard and pet waste, and certain soaps and detergents contain nitrogen and phosphorus, and can contribute to nutrient pollution if not properly used or disposed of appropriately.  The amount of hard surfaces and type of landscaping can also increase the runoff of nitrogen and phosphorus during wet weather.
