Cedar Lake algae appear nutrient‑driven, East Shore says; bacterial counts currently meet guidance
Summary
East Shore Health District reported that Cedar Lake shows increasing algae likely driven by nutrients rather than bacteria; early sampling found bacterial levels meeting the guidance thresholds, and the district is coordinating further analysis with partners.
East Shore Health District staff told the commission that ongoing monitoring at Cedar Lake shows recurring algal increases that appear more likely tied to nutrient inputs than bacterial contamination.
Sarah Esenter summarized recent sampling at Cedar Lake and said bacterial measures are within the guidance thresholds at sampled locations: "This points more towards a nutrient cause," she said, noting nitrogen and phosphorus can contribute to algal growth. The district is working with the Granite Bay Association and CTDEEP to identify sources; potential contributors discussed at the meeting included a nearby golf course, a horse farm, a quarry and residential fertilizers.
The district completed a sanitary survey in fall 2025 and has so far observed relatively low nutrient measurements since May 2026; staff will continue sampling and coordinate with the town and stakeholders to design interventions if needed.
