News Summary
The Rhode Island Department of Health and Department of Environmental Management have lifted harmful algae bloom advisories for three reservoirs including JL Curran, Smith and Sayles, and Wilson Reservoirs.

Advisories remain in place for Almy Pond and a new alert has been issued for Johnson’s Pond. Continuous monitoring for water safety is essential.
Cranston, RI – The Rhode Island Department of Health (RIDOH) and the Rhode Island Department of Environmental Management (DEM) have lifted harmful algae bloom advisories for three reservoirs in the state. These advisories have been rescinded for the JL Curran Reservoir in Cranston, the Smith and Sayles Reservoir in Glocester, and the Wilson Reservoir in Burrillville. Recent laboratory tests have shown that the levels of blue-green algae in these reservoirs are now low and no toxins have been detected.
Residents are reminded that contact with blue-green algae can cause various health issues. Skin contact may result in irritation to the skin, nose, eyes, and throat. Ingesting blue-green algae can lead to more severe symptoms, including stomachaches, diarrhea, vomiting, nausea, dizziness, headaches, fever, and potential liver and nervous system damage. Additionally, animals that come into contact with contaminated water may exhibit signs of poisoning, such as loss of energy, loss of appetite, vomiting, diarrhea, or any unexplained illness.
Following contact with any water that may be contaminated, both individuals and pets should wash their skin with clean water as soon as possible. It is also important to bathe and wash any contaminated clothing. Those experiencing symptoms after contact with affected water are advised to seek guidance from a healthcare provider.
Current Advisories for Other Water Bodies
While advisories have been lifted for the three reservoirs mentioned, an advisement remains in effect for Almy Pond in Newport due to the ongoing presence of harmful algae blooms. Officials warn against swimming, fishing, boating, and other recreational activities at this location. Furthermore, a new warning has been issued for Johnson’s Pond in Coventry, where blue-green algae blooms have been detected, urging residents to avoid any contact with the water.
Understanding Blue-Green Algae
Blue-green algae, also known as cyanobacteria, can produce harmful toxins that affect both humans and pets. Public health officials emphasize the importance of being cautious around waters known to be contaminated. Residents are specifically advised not to drink untreated water or consume fish from affected water bodies. Advisories will remain in effect for all areas with identified harmful algae blooms until further notice.
Conditions that lead to algae blooms can change rapidly, and visibility of blooms may not reliably indicate safety. Therefore, ongoing vigilance is crucial. Pet owners are particularly encouraged to refrain from allowing their pets to drink or swim in waters that have been reported as contaminated.
Reporting Algae Blooms
Residents who suspect the presence of harmful algae blooms are encouraged to report their observations to DEM’s Office of Water Resources. This serves to ensure community safety and improve monitoring of water quality across the state.
For further information, residents can access resources provided by the health department regarding blue-green algae and associated health risks.
