Public Health Advisory for Pontoosuc Lake

Print Story | Email Story
PITTSFIELD, Mass. Be advised that recent observations results have confirmed the presence of a blue-green algae bloom at Pontoosuc Lake that may present harmful health effects for users of the lake.
 
This public health advisory impacts all access points to the lake in Pittsfield and Lanesborough. Accordingly, and as recommended by the Massachusetts Department of Public Health, a public health advisory is being issued. Waterbody poses risk for people and pets.
  • Do not swim.
  • Do not swallow water.
  • Keep animals away.
  • Rinse off after contact with water.
Warning signs are being posted around the lake.
 
Blue-green algae, also known as Cyanobacteria, occur naturally in lakes and ponds throughout Massachusetts. These microscopic organisms are components of the aquatic food chain. In ordinary circumstances, Cyanobacteria cause no apparent harm. However, warmer water temperatures and high nutrient concentrations may induce a rapid increase in their abundance. This response is commonly called a "bloom" because algal biomass increases to the extent that normally clear water becomes markedly turbid.
 
Harmful health effects from the bloom can result through skin contact with the algae tainted water, swallowing the water, and when airborne droplets are inhaled. Pets are especially prone to the health effects not only through skin contact, but also by ingesting significant amounts of the toxin by licking their wet fur after leaving the water.
 
To protect yourself and your family from any harmful effects of this blue-green algae bloom, residents and visitors are advised to avoid contacting water that has a noxious odor, appears green throughout (sometimes referred to as looking like pea soup), or that has mats, films or scums accumulating on the surface.
 
Until further notice, avoid these high-risk activities:
  • Any contact with the water including swimming, diving, playing, or wading
  • Drinking, or allowing animals to drink the water
  • Water sports, e.g. water skiing, wake boarding, wind surfing, jet skiing, tubing
Other activities that pose a moderate risk to health include:
  • Fish consumption
  • Canoeing
  • Rowing
  • Sailing
  • Kayaking
  • Paddle boarding
  • Motor boating
The health outcomes of concern are:
  • Irritations of the skin, eyes or ears
  • GI problems like vomiting and diarrhea
  • Muscle cramps
  • In extreme cases nerve or liver problems
If you or your pet accidentally come in contact with algae tainted water, then thoroughly rinse off with clean water.
If you experience any of the symptoms of blue-green algae exposure (listed above) contact your health care provider or call Poison Control at 1-800-222-1222. If your pet experiences symptoms, contact your veterinarian immediately.
 
Regular monitoring of lake conditions will occur moving forward until bloom dissipates. The community will be notified of the bloom dissipation at that time. The rescinding of the public health advisory will only occur after two successive samples, collected a week apart, demonstrate cell counts or toxin levels below the state guideline values.
 
For more information or questions, please contact the Pittsfield Health Department at 413-499-9411

Possible Measles Exposure at Boston, Logan

BOSTON — The Massachusetts Department of Public Health confirmed Wednesday that an out-of-state adult visitor who spent time in Boston and Westborough earlier this month was diagnosed with measles and was present in a number of locations.
 
This could have resulted in other people being exposed to measles virus.
 
The visitor arrived at Logan International Airport on American Airlines flight 2384 from Dallas-Fort Worth, Texas, on Dec. 11 at 2:39 p.m. They stayed at the DoubleTree by Hilton Hotel Boston-Westborough in Westborough and departed the state on Dec. 12 via Logan at 9:19 p.m. on JetBlue flight 117 to Las Vegas.
 
DPH is working with the U.S. Centers for Disease Control and Prevention and local partners to identify and notify those who may have been exposed to measles from this individual.
 
"Measles is a highly contagious, airborne disease, which has increased significantly in the United States because of the unfortunate decrease in vaccination rates. It is also a preventable disease," said Public Health Commissioner Dr. Robbie Goldstein. "This current situation serves as an important reminder of the critical role vaccination plays in protecting our communities. While Massachusetts has not had a measles case this year, 2025 saw the highest number of nationwide cases in more than a decade — nearly 2,000 in 44 jurisdictions, and sadly, three deaths. 
 
"Fifteen years ago, measles had been considered eliminated in the United States, but that tremendous progress is at risk. Vaccines are one of the most important public health interventions ever — they are safe, effective, and lifesaving."
 
Measles is very contagious. However, the risk to most people in Massachusetts is low because the vaccination rate in the state is high. People who are not immune and visited any of the locations on the following dates and times may be at risk for developing measles.
