Rhode Island lifts algae advisory at Lake Mishnock, warns off two other reservoirs

State health and environmental officials say a harmful algae bloom has cleared at the West Greenwich lake, but are urging people to stay out of Wenscott Reservoir in North Providence and Oak Swamp Reservoir in Johnston.

State officials have lifted their recommendation that people avoid swimming, boating and other recreation at Lake Mishnock in West Greenwich, saying a harmful algae bloom there has cleared.

At the same time, the Rhode Island Department of Health and the Department of Environmental Management said Friday that people should avoid contact with Wenscott Reservoir in North Providence and Oak Swamp Reservoir in Johnston, where blooms of blue-green algae, also known as cyanobacteria, have been found. Water samples were collected by the environmental agency and tested at the state health laboratories, the departments said.

All recreation at the two reservoirs, including swimming, fishing, boating and kayaking, is high risk and should be avoided, the agencies said. They said people should be careful in all parts of both reservoirs, because blooms can shift position within a pond or lake. People should not drink untreated water or eat fish from the affected waters, and pets should not be allowed to drink or swim in them, the agencies said.

Blue-green algae occur naturally in bodies of water and can produce toxins harmful to people and animals, according to the health department. Skin contact can cause rashes, a sore throat and irritation of the eyes and nose, and swallowing the water can cause stomach pain, diarrhea, vomiting and nausea. More serious effects, which the agencies described as less common, can involve the liver and nervous system, an irregular heartbeat, dizziness or seizures.

The advisory will remain in place until testing shows the blooms have cleared, the agencies said. Suspected blooms can be reported to the environmental agency's Office of Water Resources.
