Toxic Algae Bloom Prompts Testing at Centennial Park's Lake Watauga
Photo: AI-generated imageState environmental officials have flagged a cyanobacterial bloom in the lake at Centennial Park, one of Nashville's most-visited green spaces near the Parthenon and Vanderbilt.
The Tennessee Department of Environment and Conservation notified Metro Parks this week that a cyanobacterial bloom had been observed in Lake Watauga, the lake at the heart of Centennial Park.
Visitors strolling past the Parthenon or picnicking in the park should avoid contact with the water and keep pets away until testing confirms it's safe; the rest of the park, including the Parthenon and greenway paths, remains open as usual.
