Health officials lift algae advisory at Lake Tiogue and Oak Swamp Reservoir

Rhode Island health and environmental officials said testing showed the blue-green algae bloom has cleared at the Coventry and Johnston waterbodies, with low algae levels and no toxins detected.

Rhode Island officials have lifted their recommendation that people avoid swimming, boating and other recreation at Lake Tiogue in Coventry and Oak Swamp Reservoir in Johnston, saying a harmful algae bloom at both waterbodies has cleared.

The state Department of Health and the Department of Environmental Management said Friday that recent laboratory testing of water samples found algae levels were low and that no toxins were detected, meeting state safety guidelines.

The advisories had been issued because of a bloom of blue-green algae, also known as cyanobacteria, which can produce toxins harmful to people and animals.

The two agencies cautioned that conditions can change quickly. Water affected by a bloom may show bright to dark green scum along the shoreline and thick floating mats on the surface, and can look like green paint, pea soup or green cottage cheese, the agencies said. People and pets should stay out of water that looks that way, according to the agencies, which said toxins can remain in the water after a bloom is no longer visible.

The environmental agency's Office of Water Resources takes reports of suspected blue-green algae blooms, and asks that a photograph be included when possible. The department also maintains an online dashboard listing current advisories and water testing data.
