Oxford's Jackson Cove Beach will be closed to swimming through Labor Day Weekend while officials test the water for blue-green algae.
The park and playground will remain open, but the water is off-limits to swimmers, according to an announcement posted on the Oxford Parks and Recreation website. Kayaking and boating is still permitted as long as residents avoid touching the water.
"Stay away from dried algae on the sand near the water," officials wrote. "It is toxic."
Town officials are also warning beach-goers to keep pets out of the water. Dogs are especially at risk, according to the Department of Energy and Environmental Protection.
Blue-green algae, which is also known as cyanobacteria, occurs naturally in lakes and ponds throughout the state. While the microscopic organisms cause no harm, blue-green algae blooms can release toxins and people and animals using the water for recreation can be affected.
Swimming areas at two Connecticut state parks are also closed because of blue-green algae blooms.
