Rhode Island health and environmental officials are lifting recreational advisories that have been in place for a number of bodies of water because of a blue-green algae known as cyanobacteria.
The Rhode Island Department of Health and the state Department of Environmental Management announced earlier this week that seasonal cooling and declining daylight have signaled a great reduction in risk. But that doesn't guarantee the toxins are absent.
Officials warn that a warm spell could trigger an algae bloom during the winter or spring.
The advisories are lifted in ponds and reservoirs in six communities. One warning remains in Little Compton.
