Update: North Pond Algae
Purpose of This Update
This communication is intended to provide residents with factual information regarding a suspected cyanobacteria (blue-green algae) bloom in North Pond and to share information received from public health authorities. QQLA has no authority regarding management of algae bloom, however we feel that it inherently important to facilitate communication and provide updates as information becomes available.
Current Situation
On June 29, 2026, a resident reported a suspected cyanobacteria bloom in North Pond and provided photographs and observations this information was relayed along to the Brookfield Board of Health (BBOH). The Brookfield Board of Health has taken the appropriate actions and had informed and consulted with the Massachusetts Department of Public Health (MDPH) and it is anticipated that the BBOH will be posting precautionary advisories at public access points in accordance with the MDPH guidelines.
At this time, no closure of the pond or boat ramps has been announced.
Sampling and Evaluation Process
The Brookfield Board of Health has advised that water samples are expected to be collected and analyzed in accordance with procedures established by the Massachusetts Department of Public Health. Any public health advisories, recommendations, restrictions, or decisions regarding their removal will be determined by the Brookfield Board of Health and the Massachusetts Department of Public Health based upon the available scientific information and laboratory results.
Because each cyanobacteria event is unique, it is not possible at this time to predict the duration of any advisory or the outcome of laboratory testing.
Public Health Information
Public health authorities have previously advised that when cyanobacteria blooms are suspected or confirmed, residents may be encouraged to:
• Avoid swimming or other direct contact with affected water.
• Avoid swallowing lake water.
• Keep pets and other animals away from affected areas.
• Rinse thoroughly if contact with affected water occurs.
• Avoid consuming fish taken from affected waters.
Residents should follow any specific guidance issued by the Brookfield Board of Health and the Massachusetts Department of Public Health regarding this event.
About Cyanobacteria Blooms
According to information published by environmental and public health agencies, cyanobacteria blooms may be influenced by several environmental conditions, including:
• Elevated phosphorus levels, which may increase following heavy rainfall and watershed runoff.
• Warm water temperatures.
• Extended periods of sunlight.
• Low water turbulence.
• Longer water residence times.
• Thermal stratification of lakes and ponds.
• Limited natural grazing by aquatic organisms.
Role of QQLA
QQLA's role is to communicate publicly available information, share updates received from governmental agencies, and support informed awareness among residents. QQLA does not determine whether advisories are issued, what recommendations or restrictions may be implemented, or when advisories are lifted. Those decisions are the responsibility of the Brookfield Board of Health and the Massachusetts Department of Public Health.
QQLA understands that any advisory concerning North Pond is of significant concern to residents. We are committed to providing timely updates as additional information becomes available from the appropriate public health authorities.
Flow Barrier
The Flow Barrier was reopened at 6pm on July 3rd when the lake levels reached equilibrium per the order of conditions.
