BURLINGTON, Vt. (WCAX) You can now check online to find out whether blue-green algae is affecting beaches and state parks around Lake Champlain.
Several Vermont and Lake Champlain protection groups teamed up to develop a cyanobacteria tracker.
You can learn how to identify algae blooms, check beach conditions and find out how to report blooms to the state.
The lake stewardship manager at the Echo Leahy Center for Lake Champlain, Barry Lampke, says high levels of phosphorus can be harmful.
"Nutrients in the right amount are great for growing things. Nutrients in excess capacities are a problem, particularly for feeding the algae blooms in Lake Champlain," Lampke said.
According to the tracker site, widespread monitoring usually ends in September. But you can always call the agency or town responsible for the beach or park to ask about conditions.
