Montgomery Parks Reports Elevated Microcystin Levels at Lake Needwood; Visitors Asked to Use Caution

Pet owners urged to keep dogs out of the lake; boating and fishing remain open.

SILVER SPRING, MDMontgomery Parks, part of the Maryland-National Capital Park and Planning Commission is asking residents to use caution when recreating on or near Lake Needwood 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 the 75-acre lake. Microcystin, hepatoxin, can cause harm to the liver of humans and pets. 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:

 

  • Keep dogs on leash (as is regularly required at the park), and do not allow them to drink or go in the water
  • Swimming is prohibited in the lake at all times
  • Wash hands thoroughly if they come in contact with the water
  • Only eat properly cooked muscle meat of fish that are caught in the lake

Boating and fishing will remain open at the lake.

 

“We have posted signs around Lake Needwood and urge visitors to please pay attention to these precautions to avoid any harm from microcystin,” said Jai Cole, Natural Resources Manager for Montgomery Parks. “Portions of the lake may be contaminated for the rest of the season. We will continue to monitor and update signs when the warning is lifted.”
