A handful of harmful algae blooms have struck the Adirondacks this summer, according to state environmental regulators.
Many blooms are inconvenient and ugly, but some are the product of toxic cyanobacteria that are often called and mistaken for algae. Without lab results, it’s impossible to know which is which, but officials tend to err on the side of caution now.
Inside the park’s boundaries, the state has identified five blooms it labels harmful, meaning not just icky but risky for people swimming in or drinking from the water. That figure, though, is sort of an undercount because it doesn’t include other blooms along Lake Champlain that are tracked by officials in Vermont.
A separate bloom tracker for Lake Champlain shows a series of blooms along the edge of the Adirondacks and the lake, though the ones happening now have been labeled “generally safe.”
