Pet owners urged to keep dogs out of the lake; boating and fishing remain open.
SILVER SPRING, MD—Montgomery Parks, part of the Maryland-National Capital Park and Planning Commission is asking residents to use caution when recreating on or near Lake Needwood and Lake Frank located within Rock Creek Regional Park. Testing has shown there are elevated levels of microcystin, a toxic substance produced by some species of blue-green algae (cyanobacteria), in both lakes. Microcystin, a hepatotoxin, can cause harm to the liver of humans and pets if ingested. Of particular concern are dogs that are off-leash and may swim and/or drink from the lake, despite park regulations. Montgomery Parks urges visitors to take the following precautions:
Recreational activities including boating and fishing will remain open at the lake.
Signs have been posted around Lake Needwood and Lake Frank indicating that elevated levels of microcystin have been found, and to urge visitors to take precautions. Portions of both lakes may be contaminated for the rest of the season. Montgomery Parks will continue to monitor the lakes and update signs when the warning is lifted.
