The state departments of Health and Environmental Management say Watson Reservoir in Little Compton and Gardiner Pond in Middletown should be avoided because of blue-green algae, or cyanobacteria, blooms that can harm humans and animals.
People should avoid recreational activities around these waters, and shouldn't drink or eat fish from them. Pets also shouldn't be allowed to drink or swim in the affected water.
Contact can cause irritation of the skin, nose, eyes, and throat. Drinking the water can cause diarrhea, vomiting and nausea.
Although both Watson Reservoir and Gardiner Pond are drinking water sources, neither is currently being used to deliver drinking water to residents.
